NAME

       amanda.conf - Main configuration file for Amanda, the Advanced Maryland
       Automatic Network Disk Archiver

DESCRIPTION

       amanda.conf(5) is the main configuration file for Amanda. This manpage
       lists the relevant sections and parameters of this file for quick
       reference.

       The file <CONFIG_DIR>/<config>/amanda.conf is loaded.

SYNTAX

       There are a number of configuration parameters that control the
       behavior of the Amanda programs. All have default values, so you need
       not specify the parameter in amanda.conf if the default is suitable.

   COMMENTS
       Lines starting with # are ignored, as are blank lines. Comments may be
       placed on a line with a directive by starting the comment with a #. The
       remainder of the line is ignored.

   KEYWORDS AND IDENTIFIERS
       Keywords are case insensitive, i.e.  mailto and MailTo are treated the
       same. Also, the characters ´-´ and ´_´ are interchangeable in all
       predefined Amanda keywords: device_property and device-property have
       the same meaning.

       Identifiers are names which are defined in the configuration itself,
       such as dumptypes or interfaces. Identifiers are are case-insensitive,
       but sensitive to ´-´ vs. ´_´. Identifiers should be quoted in the
       configuration file, although For historical reasons, the quotes are
       optional.

       Strings are always quoted with double quotes ("), and any double quotes
       or backslashes within the string are escaped with a backslash:

       tapelist "/path/to/tapelist"
       property "escaped-string" "escaping: \\ (backslash) and \" (double-quote)"

       To summarize, then:

                                 # QUOTES        CASE            -/_
       logdir "logs"             # required      sensitive       sensitive
       send-amreport-on strange  # prohibited    insensitive     insensitive
       tapetype "EXABYTE"        # optional      insensitive     sensitive

       define dumptype "dt" {    # optional      insensitive     sensitive
         "dumptype-common"       # optional      insensitive     sensitive
         strategy noincr         # prohibited    insensitive     insensitive
       }

   VALUE SUFFIXES
       Integer arguments may have one of the following (case insensitive)
       suffixes, some of which have a multiplier effect:

       b byte bytes
           Some number of bytes.

       bps
           Some number of bytes per second.

       k kb kbyte kbytes kilobyte kilobytes
           Some number of kilobytes (bytes*1024).

       kps kbps
           Some number of kilobytes per second (bytes*1024).

           It is the default multiplier for all size options.

       m mb meg mbyte mbytes megabyte megabytes
           Some number of megabytes (bytes*1024*1024).

       mps mbps
           Some number of megabytes per second (bytes*1024*1024).

       g gb gbyte gbytes gigabyte gigabytes
           Some number of gigabytes (bytes*1024*1024*1024).

       t tb tbyte tbytes terabyte terabytes
           Some number of terabytes (bytes*1024*1024*1024*1024).

       tape tapes
           Some number of tapes.

       day days
           Some number of days.

       week weeks
           Some number of weeks (days*7).

               Note
               The value inf may be used in most places where an integer is
               expected to mean an infinite amount.

               Boolean arguments may have any of the values 1, y, yes, t, true
               or on to indicate a true state, or 0, n, no, f, false or off to
               indicate a false state. If no argument is given, true is
               assumed.

   PARAMETER ORDER
       In general, the order in which parameters occur in the configuration
       file does not matter, with the exception of subsection inheritance. For
       example, if dumptype "normal-encrypt" which inherits from dumptype
       "normal", then "normal" must appear first in the configuration file.

   STRINGS
       Quoted strings in Amanda follow a common, C-like syntax. Printable
       characters and whitespace are kept as-is, except that the backslash
       character (\) is used as an escape character, and a double-quote ends
       the string. The allowed escape sequences are

           ESCAPE SEQUENCE     BECOMES
           \\                  \
           \"                  "
           \n                  (newline)
           \t                  (tab)
           \r                  (carriage return)
           \f                  (form-feed)
           \1 - \7
           \01 - \77
           \001 - \377         (character specified in octal)
       Illegally quoted strings are handled on a "best-effort" basis, which
       may lead to unexpected results.

       Examples:

       finserver "/data/finance/XYZ Corp´s \"real\" finances" finance-high eth0 -1
       property "syspath" "C:\\WINDOWS\\SYSTEM"

   SUBSECTIONS AND INHERITANCE
       Amanda configuration files may include various subsections, each
       defining a set of configuration directives. Each type of subsection is
       described below. Note that all types of subsections can inherit from
       other subsections of the same type by naming the "parent" section in
       the "child" subsection. For example:

       define dumptype global {
           record yes
           index yes
       }

       define dumptype nocomp {
           global      # inherit the parameters in dumptype ´global´
           compress none
       }

       Note that multiple inheritance is also supported by simply naming
       multiple parent sections in a child. Parents are implicitly expanded in
       place in a child, and the last occurrence of each parameter takes
       precedence. For example,

       define tapetype par1 {
           comment "Parent 1"
           filemark 8k
           speed 300bps
           length 200M
       }
       define tapetype par2 {
           comment "Parent 2"
           filemark 16k
           speed 400bps
       }
       define tapetype child {
           par1
           par2
           filemark 32k
       }
       In this example, ´child´ will have a filemark of 32k, a speed of
       400bps, and a length of 200M.

GLOBAL PARAMETERS

       org string
           Default: "daily". A descriptive name for the configuration. This
           string appears in the Subject line of mail reports. Each Amanda
           configuration should have a different string to keep mail reports
           distinct.

       mailer string
           Default found by configure. A mail program that can send mail with
           ´MAILER -s "subject" user < message_file´.

       mailto string
           Default: none. A space separated list of recipients for mail
           reports. If not specified, amdump will not send any mail.

       send-amreport-on [ all | strange | error | never ]
           Default: all. Specify which types of messages will trigger an email
           from amreport. amreport is used by amdump and amflush.

           all
               Send an email on any message.

           strange
               Send an email on strange or error message. A strange message
               occurs when the dump succeeded, but returned one or more errors
               unknown to Amanda.

           error
               Send an email only on error messages.

           never
               Never send an email.

       dumpcycle int
           Default: 10 days. The number of days in the backup cycle. Each disk
           will get a full backup at least this often. Setting this to zero
           tries to do a full backup each run.

               Note
               This parameter may also be set in a specific dumptype (see
               below). This value sets the default for all dumptypes so must
               appear in amanda.conf before any dumptypes are defined.

       runspercycle int
           Default: same as dumpcycle. The number of amdump runs in dumpcycle
           days. A value of 0 means the same value as dumpcycle. A value of -1
           means guess the number of runs from the tapelist(5) file, which is
           the number of tapes used in the last dumpcycle days / runtapes.

       tapecycle int
           Default: 15 tapes. Typically tapes are used by Amanda in an ordered
           rotation. The tapecycle parameter defines the size of that
           rotation. This parameter must be be larger than the number of tapes
           used in a dumpcycle.

           The number of tapes per dumpcycle is calculated by multiplying the
           number of amdump runs per dump cycle runspercycle (the number of
           amdump runs per dump cycle) and runtapes (the number of tapes used
           per run). Typically tapecycle is set to two or four times the tapes
           per dumpcycle.

               Note
               Amanda is commonly misconfigured with tapecycle equal to the
               number of tapes per dumpcycle.  In this misconfiguration,
               amanda may erase a full dump before a new one is completed, the
               recovery is then impossible. tapecycle must be at least one
               tape larger than the number of tapes per dumpcycle.
           While Amanda is always willing to use a new tape in its rotation,
           it refuses to reuse a tape until at least ´tapecycle -1´ number of
           other tapes have been used.

           It is considered good administrative practice to set the tapecycle
           parameter slightly lower than the actual number of tapes in
           rotation. This allows the administrator to more easily cope with
           damaged or misplaced tapes or schedule adjustments that call for
           slight adjustments in the rotation order.

       usetimestamps bool
           Default: Yes. This option allows Amanda to track multiple runs per
           calendar day. The only reason one might disable it is that Amanda
           versions before 2.5.1 can´t read logfiles written when this option
           was enabled.

       label_new_tapes string
           Deprecated, use autolabel option.

           Default: not set. When set, this directive will cause Amanda to
           automatically write an Amanda tape label to any blank tape she
           encounters. This option is DANGEROUS because when set, Amanda will
           ERASE any non-Amanda tapes you may have, and may also ERASE any
           near-failing tapes. Use with caution.

           When using this directive, specify the template for new tape
           labels. The template should contain some number of contiguous ´%´
           characters, which will be replaced with a generated number. Be sure
           to specify enough ´%´ characters that you do not run out of tape
           labels. Example: label_new_tapes "DailySet1-%%%"

       autolabel string [any] [other_config] [non_amanda] [volume_error]
       [empty]
           Default: not set. When set, this directive will cause Amanda to
           automatically write an Amanda tape label to most volume she
           encounters. This option is DANGEROUS because when set, Amanda may
           erase near-failing tapes or tapes accidentally loaded in the wrong
           slot.

           When using this directive, specify the template for new tape
           labels. The template should contain some number of contiguous ´%´
           characters, which will be replaced with a generated number. Be sure
           to specify enough ´%´ characters that you do not run out of tape
           labels. Example: autolabel "DailySet1-%%%" empty

           any
               equivalent to ´other_config non_amanda volume_error empty´

           other_config
               Label volumes with a valid Amanda label that do not match our
               labelstr. Danger: this may erase volumes from other Amanda
               configurations without warning!

           non_amanda
               Label volumes which do not start with data that resembles an
               Amanda header. Danger: this may erase volumes from other backup
               applications without warning!

           volume_error
               Label volumes where an error occurs while trying to read the
               label.  Danger: this may erase arbitrary volumes due to
               transient errors.

           empty
               Label volumes where a read returns 0 bytes.

       dumpuser string
           Default: "amanda". The login name Amanda uses to run the backups.
           The backup client hosts must allow access from the tape server host
           as this user via .rhosts or .amandahosts, depending on how the
           Amanda software was built.

       printer string
           Printer to use when doing tape labels. See the lbl-templ tapetype
           option.

       tapedev string
           Default: "null:". The device name, referencing the name of a
           "device" section in the configuration file. See amanda-devices(7)
           for more information on device names.

           If a tape changer is configured (see the tpchanger option), this
           option might not be used.

           If tapedev is null:, programs such as amdump will run normally but
           all images will be thrown away. This should only be used for
           debugging and testing, and probably only with the record option set
           to no.

       device_property string string
           These options can set various device properties. See amanda-
           devices(7) for more information on device properties and their
           syntax. Both strings are always quoted; the first string contains
           the name of the property to set, and the second contains its value.
           For example, to set a fixed block size of 128k, write:
           device_property "BLOCK_SIZE" "128k"

       property [append] string string+
           These options can set various properties, they can be used by third
           party software to store information in the configuration file. Both
           strings are quoted; the first string contains the name of the
           property to set, and the others contains its values.  append
           keyword append the values to the list of values for that property.

       tpchanger string
           Default: not set. The name of the tape changer. If a tape changer
           is not configured, this option is not used and should be commented
           out of the configuration file.

           If a tape changer is configured, choose one of the changer scripts
           (e.g.  chg-scsi) and enter that here.

       changerdev string
           Default: "dev/null". A tape changer configuration parameter. Usage
           depends on the particular changer defined with the tpchanger
           option.

       changerfile string
           Default: "usr/adm/amanda/log/changer-status". A tape changer
           configuration parameter. Usage depends on the particular changer
           defined with the tpchanger option.

       runtapes int
           Default: 1. The maximum number of tapes used in a single run. If a
           tape changer is not configured, this option is not used and should
           be commented out of the configuration file.

           If a tape changer is configured, this may be set larger than one to
           let Amanda write to more than one tape.

           Note that this is an upper bound on the number of tapes, and Amanda
           may use less.

           Also note that as of this release, Amanda does not support true
           tape overflow. When it reaches the end of one tape, the backup
           image Amanda was processing starts over again on the next tape.

       maxdumpsize int
           Default: runtapes*tape_length. Maximum number of bytes the planner
           will schedule for a run.

           The default unit is Kbytes if it is not specified.

       taperalgo [ first | firstfit | largest | largestfit | smallest | last ]
           Default: first. The algorithm used to choose which dump image to
           send to the taper.

           first
               First in, first out.

           firstfit
               The first dump image that will fit on the current tape.

           largest
               The largest dump image.

           largestfit
               The largest dump image that will fit on the current tape.

           smallest
               The smallest dump image.

           last
               Last in, first out.

       labelstr string
           Default: ".*". The tape label constraint regular expression. All
           tape labels generated (see amlabel(8)) and used by this
           configuration must match the regular expression. If multiple
           configurations are run from the same tape server host, it is
           helpful to set their labels to different strings (for example,
           "DAILY[0-9][0-9]*" vs. "ARCHIVE[0-9][0-9]*") to avoid overwriting
           each other´s tapes.

       tapetype string
           Default: no default. The type of tape drive associated with tapedev
           or tpchanger. This refers to one of the defined tapetypes in the
           config file (see below), which specify various tape parameters,
           like the length, filemark size, and speed of the tape media and
           device.

       ctimeout int
           Default: 30 seconds. Maximum amount of time that amcheck will wait
           for each client host.

       dtimeout int
           Default: 1800 seconds. Amount of idle time per disk on a given
           client that a dumper running from within amdump will wait before it
           fails with a data timeout error.

       etimeout int
           Default: 300 seconds. Amount of time per estimate on a given client
           that the planner step of amdump will wait to get the dump size
           estimates (note: Amanda runs up to 3 estimates for each DLE). For
           instance, with the default of 300 seconds and four DLE´s, each
           estimating level 0 and level 1 on client A, planner will wait up to
           40 minutes for that machine. A negative value will be interpreted
           as a total amount of time to wait per client instead of per disk.

       connect_tries int
           Default: 3. How many times the server will try a connection.

       req_tries int
           Default: 3. How many times the server will resend a REQ packet if
           it doesn´t get the ACK packet.

       netusage int
           Default: 8000 Kbps. The maximum network bandwidth allocated to
           Amanda, in Kbytes per second. See also the interface section.

       inparallel int
           Default: 10. The maximum number of backups that Amanda will attempt
           to run in parallel. Amanda will stay within the constraints of
           network bandwidth and holding disk space available, so it doesn´t
           hurt to set this number a bit high. Some contention can occur with
           larger numbers of backups, but this effect is relatively small on
           most systems.

       displayunit "k|m|g|t"
           Default: "k". The unit used to print many numbers, k=kilo, m=mega,
           g=giga, t=tera.

       dumporder string
           Default: "tttTTTTTTT". The priority order of each dumper:

           s: smallest size
           S: largest size
           t: smallest time
           T: largest time
           b: smallest bandwidth
           B: largest bandwidth

       maxdumps int
           Default: 1. The maximum number of backups from a single host that
           Amanda will attempt to run in parallel. See also the inparallel
           option.

           Note that this parameter may also be set in a specific dumptype
           (see below). This value sets the default for all dumptypes so must
           appear in amanda.conf before any dumptypes are defined.

       bumpsize int
           Default: 10 Mbytes. The minimum savings required to trigger an
           automatic bump from one incremental level to the next, expressed as
           size. If Amanda determines that the next higher backup level will
           be this much smaller than the current level, it will do the next
           level. The value of this parameter is used only if the parameter
           bumppercent is set to 0.

           The default unit is Kbytes if it is not specified.

           The global setting of this parameter can be overwritten inside of a
           dumptype-definition.

           See also the options bumppercent, bumpmult and bumpdays.

       bumppercent int
           Default: 0. The minimum savings required to trigger an automatic
           bump from one incremental level to the next, expressed as
           percentage of the current size of the DLE (size of current level
           0). If Amanda determines that the next higher backup level will be
           this much smaller than the current level, it will do the next
           level.

           If this parameter is set to 0, the value of the parameter bumpsize
           is used to trigger bumping.

           The global setting of this parameter can be overwritten inside of a
           dumptype-definition.

           See also the options bumpsize, bumpmult and bumpdays.

       bumpmult float
           Default: 1.5. The bump size multiplier. Amanda multiplies bumpsize
           by this factor for each level. This prevents active filesystems
           from bumping too much by making it harder to bump to the next
           level. For example, with the default bumpsize and bumpmult set to
           2.0, the bump threshold will be 10 Mbytes for level one, 20 Mbytes
           for level two, 40 Mbytes for level three, and so on.

           The global setting of this parameter can be overwritten inside of a
           dumptype-definition.

       bumpdays int
           Default: 2 days. To insure redundancy in the dumps, Amanda keeps
           filesystems at the same incremental level for at least bumpdays
           days, even if the other bump threshold criteria are met.

           The global setting of this parameter can be overwritten inside of a
           dumptype-definition.

       diskfile string
           Default: "disklist". The file name for the disklist file holding
           client hosts, disks and other client dumping information.

       infofile string
           Default: "/usr/adm/amanda/curinfo". The file or directory name for
           the historical information database. If Amanda was configured to
           use DBM databases, this is the base file name for them. If it was
           configured to use text formated databases (the default), this is
           the base directory and within here will be a directory per client,
           then a directory per disk, then a text file of data.

       logdir string
           Default: "/usr/adm/amanda". The directory for the amdump and log
           files.

       indexdir string
           Default "/usr/adm/amanda/index". The directory where index files
           (backup image catalogues) are stored. Index files are only
           generated for filesystems whose dumptype has the index option
           enabled.

       tapelist string
           Default: "tapelist". The file name for the active tapelist(5).
           Amanda maintains this file with information about the active set of
           tapes.

       device_output_buffer_size int
           Default: 1280k. Controls the amount of memory used by Amanda to
           hold data as it is read from the network or disk before it is
           written to the output device. Higher values may be useful on fast
           tape drives and optical media.

           The default unit is bytes if it is not specified.

       tapebufs int
           Default: 20. This option is deprecated; use the
           device_output_buffer_size directive instead.  tapebufs works the
           same way, but the number specified is multiplied by the device
           blocksize prior to use.

       reserve int
           Default: 100. The part of holding-disk space that should be
           reserved for incremental backups if no tape is available, expressed
           as a percentage of the available holding-disk space (0-100). By
           default, when there is no tape to write to, degraded mode
           (incremental) backups will be performed to the holding disk. If
           full backups should also be allowed in this case, the amount of
           holding disk space reserved for incrementals should be lowered.

       autoflush bool
           Default: off. Whether an amdump run will flush the dumps from
           holding disk to tape.

       amrecover_do_fsf bool
           Default: on. Amrecover will call amrestore with the -f flag for
           faster positioning of the tape.

       amrecover_check_label bool
           Default: on. Amrecover will call amrestore with the -l flag to
           check the label.

       amrecover_changer string
           Default: not set. Amrecover will use the changer if you use
           ´settape <string>´ and that string is the same as the
           amrecover_changer setting.

       columnspec string
           default:
           "HostName=0:12:12,Disk=1:11:11,Level=1:1:1,OrigKB=1:-7:0,OutKB=1:-7:0,Compress=1:-6:1,DumpTime=1:-7:7,Dumprate=1:-6:1,TapeTime=1:-6:6,TapeRate=1:-6:1"

           Defines the width of columns amreport should use.  String is a
           comma (´,´) separated list of triples. Each triple consists of
           three parts which are separated by a equal sign (´=´) and a colon
           (´:´) (see the example). These four parts specify:

            1. the name of the column, which may be:

                    Compress (compression ratio)
                    Disk (client disk name)
                    DumpRate (dump rate in KBytes/sec)
                    DumpTime (total dump time in hours:minutes)
                    HostName (client host name)
                    Level (dump level)
                    OrigKB (original image size in KBytes)
                    OutKB (output image size in KBytes)
                    TapeRate (tape writing rate in KBytes/sec)
                    TapeTime (total tape time in hours:minutes)

            2. the amount of space to display before the column (used to get
               whitespace between columns).

            3. the width of the column itself. If set to a negative value, the
               width will be calculated on demand to fit the largest entry in
               this column.

            4. the precision of the column, number of digit after the decimal
               point for number.

           Here is an example:

           columnspec "Disk=1:18,HostName=0:10,OrigKB=::2,OutKB=1:7"

           The above will display the disk information in 18 characters and
           put one space before it. The hostname column will be 10 characters
           wide with no space to the left. The Original KBytes print 2 decimal
           digit. The output KBytes column is seven characters wide with one
           space before it.

       includefile string
           Default: no default. The name of an Amanda configuration file to
           include within the current file. Useful for sharing dumptypes,
           tapetypes and interface definitions among several configurations.
           Relative pathnames are relative to the configuration directory.

       debug_days int
           Default: 3. The number of days the debug files are kept.

       debug_auth int
           Default: 0. Debug level of the auth module

       debug_event int
           Default: 0. Debug level of the event module

       debug_holding int
           Default: 0. Debug level of the holdingdisk module

       debug_protocol int
           Default: 0. Debug level of the protocol module

       debug_planner int
           Default: 0. Debug level of the planner process

       debug_driver int
           Default: 0. Debug level of the driver process

       debug_dumper int
           Default: 0. Debug level of the dumper process

       debug_chunker int
           Default: 0. Debug level of the chunker process

       debug_taper int
           Default: 0. Debug level of the taper process

       flush-threshold-dumped int
           Default: 0. Amanda will not begin writing data to a new volume
           until the amount of data on the holding disk is at least this
           percentage of the volume size. In other words, Amanda will not
           begin until the amount of data on the holding disk is greater than
           the tape length times this parameter. This parameter may be larger
           than 100%, for example to keep more recent dumps on the holding
           disk for faster recovery.

           Needless to say, your holding disk must be big enough that this
           criterion could be satisfied. If the holding disk cannot be used
           for a particular dump (because, for example, there is no remaining
           holding space) then Amanda will disregard the constraint specified
           by this setting and start a new volume anyway. Once writing to a
           volume has begun, this constraint is not applied unless and until a
           new volume is needed.

           The value of this parameter may not exceed than that of the
           flush-threshold-scheduled parameter.

       flush-threshold-scheduled int
           Default: 0. Amanda will not begin writing data to a new volume
           until the sum of the amount of data on the holding disk and the
           estimated amount of data remaining to be dumped during this run is
           at least this percentage of the volume size. In other words, Amanda
           will not begin until the inequality h + s > t × d is satisfied,
           where h is the amount of data on the holding disk, s is the total
           amount of data scheduled for this run but not dumped yet, t is the
           capacity of a volume, and d is this parameter, expressed as a
           percentage. This parameter may be larger than 100%.

           Needless to say, your holding disk must be big enough that this
           criterion could be satisfied. If the holding disk cannot be used
           for a particular dump (because, for example, there is no remaining
           holding space) then Amanda will disregard the constraint specified
           by this setting and start a new volume anyway. Once writing to a
           volume has begun, this constraint is not applied unless and until a
           new volume is needed.

           The value of this parameter may not be less than that of the
           flush-threshold-dumped or taperflush parameters.

       taperflush int
           Default: 0. At the end of a run, Amanda will start a new tape to
           flush remaining data if there is more data on the holding disk at
           the end of a run than this setting allows; the amount is specified
           as a percentage of the capacity of a single volume. In other words,
           at the end of a run, Amanda will begin a new tape if the inequality
           h > t × f is satisfied, where h is the amount of data remaining on
           the holding disk from this or previous runs, t is the capacity of a
           volume, and f is this parameter, expressed as a percentage. This
           parameter may be greater than 100%.

           The value of this parameter may not exceed that of the
           flush-threshold-scheduled parameter.; autoflush must be set to
           ´yes´ if taperflush is greater than 0.

       reserved-udp-port int,int
           Default: --with-udpportrange or 512,1023. Reserved udp port that
           will be used (bsd, bsdudp). Range is inclusive.

       reserved-tcp-port int,int
           Default: --with-low-tcpportrange or 512,1023. Reserved tcp port
           that will be used (bsdtcp). Range is inclusive.

       unreserved-tcp-port int,int
           Default: --with-tcpportrange or 1024,65535. Unreserved tcp port
           that will be used (bsd, bsdudp). Range is inclusive.

HOLDINGDISK SECTION

       The amanda.conf file may define one or more holding disks used as
       buffers to hold backup images before they are written to tape. The
       syntax is:
       define holdingdisk name {
           holdingdisk-option holdingdisk-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       Name is a logical name for this holding disk.

       The options and values are:

       comment string
           Default: not set. A comment string describing this holding disk.

       directory string
           Default: "/dumps/amanda". The path to this holding area.

       use int
           Default: 0 Gb. Amount of space that can be used in this holding
           disk area. If the value is zero, all available space on the file
           system is used. If the value is negative, Amanda will use all
           available space minus that value.

       chunksize int
           Default: 1 Gb. Holding disk chunk size. Dumps larger than the
           specified size will be stored in multiple holding disk files. The
           size of each chunk will not exceed the specified value. However,
           even though dump images are split in the holding disk, they are
           concatenated as they are written to tape, so each dump image still
           corresponds to a single continuous tape section.

           The default unit is Kbytes if it is not specified.

           If 0 is specified, Amanda will create holding disk chunks as large
           as ((INT_MAX/1024)-64) Kbytes.

           Each holding disk chunk includes a 32 Kbyte header, so the minimum
           chunk size is 64 Kbytes (but that would be really silly).

           Operating systems that are limited to a maximum file size of 2
           Gbytes actually cannot handle files that large. They must be at
           least one byte less than 2 Gbytes. Since Amanda works with 32 Kbyte
           blocks, and to handle the final read at the end of the chunk, the
           chunk size should be at least 64 Kbytes (2 * 32 Kbytes) smaller
           than the maximum file size, e.g. 2047 Mbytes.

DUMPTYPE SECTION

       The amanda.conf(5) file may define multiple sets of backup options and
       refer to them by name from the disklist(5) file. For instance, one set
       of options might be defined for file systems that can benefit from high
       compression, another set that does not compress well, another set for
       file systems that should always get a full backup and so on.

       A set of backup options are entered in a dumptype section, which looks
       like this:
       define dumptype "name" {
           dumptype-option dumptype-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       Name is the name of this set of backup options. It is referenced from
       the disklist(5) file.

       Some of the options in a dumptype section are the same as those in the
       main part of amanda.conf(5). The main option value is used to set the
       default for all dumptype sections. For instance, setting dumpcycle to
       50 in the main part of the config file causes all following dumptype
       sections to start with that value, but the value may be changed on a
       section by section basis. Changes to variables in the main part of the
       config file must be done before (earlier in the file) any dumptypes are
       defined.

       The dumptype options and values are:

       auth string
           Default: "bsd". Type of authorization to perform between tape
           server and backup client hosts. See amanda-auth(7) for more detail.

       amandad_path string
           Default: "$libexec/amandad". Specify the amandad path of the
           client, only use with rsh/ssh authentification.

       client_username string
           Default: CLIENT_LOGIN. Specify the username to connect on the
           client, only use with rsh/ssh authentification.

       client_port [ int | string ]
           Default: "amanda". Specifies the port to connect to on the client.
           It can be a service name or a numeric port number.

       bumpsize int
           Default: 10 Mbytes. The minimum savings required to trigger an
           automatic bump from one incremental level to the next, expressed as
           size. If Amanda determines that the next higher backup level will
           be this much smaller than the current level, it will do the next
           level. The value of this parameter is used only if the parameter
           bumppercent is set to 0.

           The default unit is Kbytes if it is not specified.

           See also the options bumppercent, bumpmult and bumpdays.

       bumppercent int
           Default: 0. The minimum savings required to trigger an automatic
           bump from one incremental level to the next, expressed as
           percentage of the current size of the DLE (size of current level
           0). If Amanda determines that the next higher backup level will be
           this much smaller than the current level, it will do the next
           level.

           If this parameter is set to 0, the value of the parameter bumpsize
           is used to trigger bumping.

           See also the options bumpsize, bumpmult and bumpdays.

       bumpmult float
           Default: 1.5. The bump size multiplier. Amanda multiplies bumpsize
           by this factor for each level. This prevents active filesystems
           from bumping too much by making it harder to bump to the next
           level. For example, with the default bumpsize and bumpmult set to
           2.0, the bump threshold will be 10 Mbytes for level one, 20 Mbytes
           for level two, 40 Mbytes for level three, and so on.

       bumpdays int
           Default: 2 days. To insure redundancy in the dumps, Amanda keeps
           filesystems at the same incremental level for at least bumpdays
           days, even if the other bump threshold criteria are met.

       comment string
           Default: not set. A comment string describing this set of backup
           options.

       comprate float [, float ]
           Default: 0.50, 0.50. The expected full and incremental compression
           factor for dumps. It is only used if Amanda does not have any
           history information on compression rates for a filesystem, so
           should not usually need to be set. However, it may be useful for
           the first time a very large filesystem that compresses very little
           is backed up.

       compress [ none | client | server ] [ best | fast | custom ]
           Default: client fast. If Amanda does compression of the backup
           images, it can do so either on the backup client host before it
           crosses the network or on the tape server host as it goes from the
           network into the holding disk or to tape. Which place to do
           compression (if at all) depends on how well the dump image usually
           compresses, the speed and load on the client or server, network
           capacity, holding disk capacity, availability of tape hardware
           compression, etc.

           For either type of compression, Amanda also allows the selection of
           three styles of compression.  best is the best compression
           available, often at the expense of CPU overhead.  fast is often not
           as good a compression as best, but usually less CPU overhead. Or to
           specify custom to use your own compression method. (See dumptype
           custom-compress in example/amanda.conf for reference)

           So the compress options line may be one of:

           compress none

           compress client fast

           compress client best

           compress client custom
               Specify client_custom_compress "PROG"

               PROG must not contain white space and it must accept -d for
               uncompress.

           compress server fast

           compress server best

           compress server custom
               Specify server_custom_compress "PROG"

               PROG must not contain white space and it must accept -d for
               uncompress.

           Note that some tape devices do compression and this option has
           nothing to do with whether that is used. If hardware compression is
           used (usually via a particular tape device name or mt option),
           Amanda (software) compression should be disabled.

       client_custom_compress string
           Default: none. The program to use to perform
           compression/decompression on the client; used with "compress client
           custom". Must not contain whitespace. Must accept -d to uncompress.

       server_custom_compress string
           Default: none. The program to use to perform
           compression/decompression on the server; used with "compress server
           custom". Must not contain whitespace. Must accept -d to uncompress.

       dumpcycle int
           Default: 10 days. The number of days in the backup cycle. Each disk
           using this set of options will get a full backup at least this of
           ten. Setting this to zero tries to do a full backup each run.

       encrypt [ none | client | server ]
           Default: not set. To encrypt backup images, it can do so either on
           the backup client host before it crosses the network or on the tape
           server host as it goes from the network into the holding disk or to
           tape.

           So the encrypt options line may be one of:

           encrypt none

           encrypt client
               Specify client_encrypt "PROG"

               PROG must not contain white space.

               Specify client_decrypt_option "decryption-parameter" Default:
               "-d"

               decryption-parameter must not contain white space.

               (See dumptype client-encrypt-nocomp in example/amanda.conf for
               reference)

           encrypt server
               Specify server_encrypt "PROG"

               PROG must not contain white space.

               Specify server_decrypt_option "decryption-parameter" Default:
               "-d"

               decryption-parameter must not contain white space.

               (See dumptype server-encrypt-fast in example/amanda.conf for
               reference)

           Note that current logic assumes compression then encryption during
           backup(thus decrypt then uncompress during restore). So specifying
           client-encryption AND server-compression is not supported.  amcrypt
           which is a wrapper of aespipe is provided as a reference symmetric
           encryption program.

       client_encrypt string
           Default: none. The program to use to perform encryption/decryption
           on the client; used with "encrypt client". Must not contain
           whitespace.

       client_decrypt_option string
           Default: -d. The option that can be passed to client_encrypt to
           make it decrypt instead. Must not contain whitespace.

       server_encrypt string
           Default: none. The program to use to perform encryption/decryption
           on the server; used with "encrypt server". Must not contain
           whitespace.

       server_decrypt_option string
           Default: -d. The option that can be passed to server_encrypt to
           make it decrypt instead. Must not contain whitespace.

       estimate [ client | calcsize | server ]+
           Default: client. Determine the way Amanda estimates the size of
           each DLE before beginning a backup. This is a list of acceptable
           estimate methods, and Amanda applies the first method supported by
           the application. The methods are:

           client
               Use the same program as the dumping program. This is the most
               accurate method to do estimates, but it can take a long time.

           calcsize
               Use a faster program to do estimates, but the result is less
               accurate.

           server
               Use only statistics from the previous few runs to give an
               estimate. This very quick, but the result is not accurate if
               your disk usage changes from day to day. If this method is
               specified, but the server does not have enough data to make an
               estimate, then the option is internally moved to the end of the
               list, thereby preferring ´client´ or ´calcsize´ in this case.

       exclude [ list | file ][[optional][append][ string ]+]
           Default: file. Exclude is the opposite of include and specifies
           files that will be excluded from the backup. The format of the
           exclude expressions depends on the application, and some
           applications do not support excluding files at all.

           There are two exclude parameters, exclude file and exclude list.
           With exclude file, the string is an exclude expression. With
           exclude list , the string is a file name on the client containing
           GNU-tar exclude expressions. The path to the specified exclude list
           file, if present (see description of ´optional´ below), must be
           readable by the Amanda user.

           All exclude expressions are concatenated in one file and passed to
           the application as an --exclude-from argument.

           For GNU-tar, exclude expressions must always be specified as
           relative to the top-level directory of the DLE, and must start with
           "./". See the manpages for individual applications for more
           information on supported exclude expressions.

           With the append keyword, the string is appended to the current
           list, without it, the string overwrites the list.

           If optional is specified for exclude list, then amcheck will not
           complain if the file doesn´t exist or is not readable.

           For exclude list, if the file name is relative, the disk name being
           backed up is prepended. So if this is entered:
               exclude list ".amanda.excludes"
           the actual file used would be /var/.amanda.excludes for a backup of
           /var, /usr/local/.amanda.excludes for a backup of /usr/local, and
           so on.

       holdingdisk [ never | auto | required ]
           Default: auto. Whether a holding disk should be used for these
           backups or whether they should go directly to tape. If the holding
           disk is a portion of another file system that Amanda is backing up,
           that file system should refer to a dumptype with holdingdisk set to
           never to avoid backing up the holding disk into itself.

           never|no|false|off
               Never use a holdingdisk, the dump will always go directly to
               tape. There will be no dump if you have a tape error.

           auto|yes|true|on
               Use the holding disk, unless there is a problem with the
               holding disk, the dump won´t fit there or the medium doesn´t
               require spooling (e.g., VFS device)

           required
               Always dump to holdingdisk, never directly to tape. There will
               be no dump if it doesn´t fit on holdingdisk

       ignore boolean
           Default: no. Whether disks associated with this backup type should
           be backed up or not. This option is useful when the disklist file
           is shared among several configurations, some of which should not
           back up all the listed file systems.

       include [ list | file ][[optional][append][ string ]+]
           Default: file ".". There are two include lists, include file and
           include list.  With include file , the string is a glob expression.
           With include list , the string is a file name on the client
           containing glob expressions.

           All include expressions are expanded by Amanda, concatenated in one
           file and passed to GNU-tar as a --files-from argument. They must
           start with "./" and contain no other "/".

           Include expressions must always be specified as relative to the
           head directory of the DLE.

               Note
               For globbing to work at all, even the limited single level, the
               top level directory of the DLE must be readable by the Amanda
               user.
           With the append keyword, the string is appended to the current
           list, without it, the string overwrites the list.

           If optional is specified for include list, then amcheck will not
           complain if the file doesn´t exist or is not readable.

           For include list, If the file name is relative, the disk name being
           backed up is prepended.

       index boolean
           Default: no. Whether an index (catalogue) of the backup should be
           generated and saved in indexdir. These catalogues are used by the
           amrecover utility.

       kencrypt boolean
           Default: no. Whether the backup image should be encrypted by
           Kerberos as it is sent across the network from the backup client
           host to the tape server host.

       maxdumps int
           Default: 1. The maximum number of backups from a single host that
           Amanda will attempt to run in parallel. See also the main section
           parameter inparallel.

       maxpromoteday int
           Default: 10000. The maximum number of day for a promotion, set it 0
           if you don´t want promotion, set it to 1 or 2 if your disks get
           overpromoted.

       priority [ low | medium | high ]
           Default: medium. When there is no tape to write to, Amanda will do
           incremental backups in priority order to the holding disk. The
           priority may be high (2), medium (1), low (0) or a number of your
           choice.

       program [ "DUMP" | "GNUTAR" | "APPLICATION" ]
           Default: "DUMP". The type of backup to perform. Valid values are:

           "DUMP"
               The native operating system backup program.

           "GNUTAR"
               To use GNU-tar or to do PC backups using Samba.

           "APPLICATION"
               To use an application, see the application option.

       application string
           No default. Must be the name of an application if program is set to
           APPLICATION. See APPLICATION SECTION below.

       script string
           No default. Must be the name of a script. You can have many script.
           See SCRIPT SECTION below.

       property [append] string string+
           These options can set various properties, they can be used by third
           party software to store information in the configuration file. Both
           strings are quoted; the first string contains the name of the
           property to set, and the others contains its values.  append
           keyword append the values to the list of values for that property.

       record boolean
           Default: yes. Whether to ask the backup program to update its
           database (e.g.  /var/lib/dumpdates for DUMP or
           /usr/local/var/amanda/gnutar-lists for GNUTAR) of time stamps. This
           is normally enabled for daily backups and turned off for periodic
           archival runs.

       skip-full boolean
           Default: no. If true and planner has scheduled a full backup, these
           disks will be skipped, and full backups should be run off-line on
           these days. It was reported that Amanda only schedules level 1
           incrementals in this configuration; this is probably a bug.

       skip-incr boolean
           Default: no. If true and planner has scheduled an incremental
           backup, these disks will be skipped.

       ssh_keys string
           Default: not set. The key file the ssh auth will use, it must be
           the private key. If this parameter is not specified, then the
           default ssh key will be used.

       starttime int
           Default: not set. Backup of these disks will not start until after
           this time of day. The value should be hh*100+mm, e.g. 6:30PM
           (18:30) would be entered as 1830.

       strategy [ standard | nofull | noinc | skip | incronly ]
           Default: standard. Strategy to use when planning what level of
           backup to run next. Values are:

           standard
               The standard Amanda schedule.

           nofull
               Never do full backups, only level 1 incrementals.

           noinc
               Never do incremental backups, only full dumps.

           skip
               Treat this DLE as if it doesn´t exist (useful to disable DLEs
               when sharing the disklist file between multiple
               configurations). Skipped DLEs will not be checked or dumped,
               and will not be matched by disklist expressions.

           incronly
               Only do incremental dumps.  amadmin force should be used to
               tell Amanda that a full dump has been performed off-line, so
               that it resets to level 1.

       tape_splitsize int
           Default: not set. Split dump file on tape into pieces of a
           specified size. This allows dumps to be spread across multiple
           tapes, and can potentially make more efficient use of tape space.
           Note that if this value is too large (more than half the size of
           the average dump being split), substantial tape space can be
           wasted. If too small, large dumps will be split into innumerable
           tiny dumpfiles, adding to restoration complexity. A good rule of
           thumb, usually, is 1/10 of the size of your tape.

           The default unit is Kbytes if it is not specified.

       split_diskbuffer string
           Default: not set. When dumping a split dump in PORT-WRITE mode
           (usually meaning "no holding disk"), buffer the split chunks to a
           file in the directory specified by this option.

       fallback_splitsize int
           Default: 10M. When dumping a split dump in PORT-WRITE mode, if no
           split_diskbuffer is specified (or if we somehow fail to use our
           split_diskbuffer), we must buffer split chunks in memory. This
           specifies the maximum size split chunks can be in this scenario,
           and thus the maximum amount of memory consumed for in-memory
           splitting. The size of this buffer can be changed from its (very
           conservative) default to a value reflecting the amount of memory
           that each taper process on the dump server may reasonably consume.

           The default unit is Kbytes if it is not specified.

       The following dumptype entries are predefined by Amanda:
       define dumptype "no-compress" {
           compress none
       }
       define dumptype "compress-fast" {
           compress client fast
       }
       define dumptype "compress-best" {
           compress client best
       }
       define dumptype "srvcompress" {
           compress server fast
       }
       define dumptype "bsd-auth" {
           auth bsd
       }
       define dumptype "no-record" {
           record no
       }
       define dumptype "no-hold" {
           holdingdisk no
       }
       define dumptype "no-full" {
           skip-full yes
       }

       In addition to options in a dumptype section, one or more other
       dumptype names may be supplied as identifiers, which make this dumptype
       inherit options from other previously defined dumptypes. For instance,
       two sections might be the same except for the record option:
       define dumptype "normal" {
           comment "Normal backup, no compression, do indexing"
           no-compress
           index yes
           maxdumps 2
       }
       define dumptype "testing" {
           comment "Test backup, no compression, do indexing, no recording"
           "normal"
           record no
       }

       Amanda provides a dumptype named global in the sample amanda.conf file
       that all dumptypes should reference. This provides an easy place to
       make changes that will affect every dumptype, although you must be
       careful that every dumptype explicitly inherits from the global
       dumptype - Amanda does not do so automatically.

TAPETYPE SECTION

       The amanda.conf file may define multiple types of tape media and
       devices. The information is entered in a tapetype section, which looks
       like this in the config file:
       define tapetype "name" {
           tapetype-option tapetype-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       Name is the name of this type of tape medium/device. It is referenced
       from the tapetype option in the main part of the config file.

       The tapetype options and values are:

       comment string
           Default: not set. A comment string describing this set of tape
           information.

       filemark int
           Default: 1 kbytes. How large a file mark (tape mark) is, measured
           in kbytes. If the size is only known in some linear measurement
           (e.g. inches), convert it to kbytes using the device density.

       length int
           Default: 2000 kbytes. How much data will fit on a tape, expressed
           in kbytes.

           Note that this value is only used by Amanda to schedule which
           backups will be run. Once the backups start, Amanda will continue
           to write to a tape until it gets an error, regardless of what value
           is entered for length (but see amanda-devices(7) for exceptions).

       blocksize int
           Default: 32 kbytes. How much data will be written in each tape
           record, expressed in kbytes. This is similar to the BLOCK_SIZE
           device property, but if the blocksize is not a multiple of 1024
           bytes, then this parameter cannot be used to specify it, and the
           property must be used instead.

       readblocksize int
           Default: 32 kytes How much data will be read in each tape record.
           This can be used to override a device´s block size for reads only.
           This may be useful, for example, in reading a tape written with a
           256k block size when Amanda is configured to use 128k blocks. This
           unusual feature is not supported by all operating systems and tape
           devices.

           The default unit is Kbytes if it is not specified.

       speed int
           Default: 200 bps. How fast the drive will accept data, in bytes per
           second. This parameter is NOT currently used by Amanda.

       lbl-templ string
           Default: not set. A PostScript template file used by amreport to
           generate labels. Several sample files are provided with the Amanda
           sources in the example directory. See the amreport(8) man page for
           more information.

       In addition to options, another tapetype name may be supplie as an
       identifier, which makes this tapetype inherit options from another
       tapetype. For instance, the only difference between a DLT4000 tape
       drive using Compact-III tapes and one using Compact-IV tapes is the
       length of the tape. So they could be entered as:
       define tapetype "DLT4000-III" {
           comment "DLT4000 tape drives with Compact-III tapes"
           length 12500 mbytes         # 10 Gig tapes with some compression
           filemark 2000 kbytes
           speed 1536 kps
       }
       define tapetype "DLT4000-IV" {
           "DLT4000-III"
           comment "DLT4000 tape drives with Compact-IV tapes"
           length 25000 mbytes         # 20 Gig tapes with some compression
       }

INTERFACE SECTION

       The amanda.conf file may define multiple types of network interfaces.
       The information is entered in an interface section, which looks like
       this:
       define interface "name" {
           interface-option interface-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       name is the name of this type of network interface. It is referenced
       from the disklist file.

       Note that these sections define network interface characteristics, not
       the actual interface that will be used. Nor do they impose limits on
       the bandwidth that will actually be taken up by Amanda. Amanda computes
       the estimated bandwidth each file system backup will take based on the
       estimated size and time, then compares that plus any other running
       backups with the limit as another of the criteria when deciding whether
       to start the backup. Once a backup starts, Amanda will use as much of
       the network as it can leaving throttling up to the operating system and
       network hardware.

       The interface options and values are:

       comment string
           Default: not set. A comment string describing this set of network
           information.

       use int
           Default: 8000 Kbps. The speed of the interface in Kbytes per
           second.

       In addition to options, another interface name may be supplied as an
       identifier, which makes this interface inherit options from another
       interface. At the moment, this is of little use.

APPLICATION SECTION

       The amanda.conf file may define multiple types of application. The
       information is entered in a application section, which looks like this:
       define application "name" {
           application-option application-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       name is the name of this type of application. It is referenced from the
       dumptype

       The application options and values are:

       comment string
           Default: not set. A comment string describing this application.

SCRIPT SECTION

       The amanda.conf file may define multiple types of script. The
       information is entered in a script section, which looks like this:
       define script "name" {
           script-option script-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       name is the name of this type of script. It is referenced from the
       dumptype

       The script options and values are:

       comment string
           Default: not set. A comment string describing this script.

       plugin string

           must be in the $libexecdir/amanda/application directory on the
           client and/or server.

       order int
           Default: 5000. Scripts are executed in that order, it is useful if
           you have many scripts and they must be executed in a spefific
           order.

           script --pre-level-recover --level 0
           #recovering level 0
           script --post-level-recover --level 0
           script --inter-level-recover --level 0 --level 2
           script --pre-level-recover --level 2

DEVICE SECTION

       Backend storage devices are specified in amanda.conf in the form of
       "device" sections, which look like this:
       define device name {
           commend "comment (optional)"
           tapedev "device-specifier"
           device_property "prop-name" "prop-value"
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       name is the user-specified name of this device. It is referenced from
       the global tapedev parameter. The device-specifier specifies the device
       name to use; see amanda-devices(7). As with most sections, the comment
       parmeter is optional and only for the user´s convenience.

       An arbitrary number of device_property parameters can be specified.
       Again, see amanda-devices(7) for information on device properties.

CHANGER SECTION

       Changers are described in amanda.conf in the form of "changer"
       sections, which look like this:
       define changer name {
           comment "comment (optional)"
           tpchanger "changer-spec"
           changerdev "device-name"
           changerfile "state-file"
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       name is the user-specified name of this device. The remaining
       parameters are specific to the changer type selected.

       See amanda-changers(7) for more information on configuring changers.
