       backup_adddump - Defines a dump level in the dump hierarchy


       backup adddump -dump <dump level name>+
           [-expires <expiration date>+]
           [-localauth] [-cell <cell name>] [-help]

       backup addd -d <dump level name>+
           [-e <expiration date>+]
           [-l] [-c <cell name>] [-h]


       The backup adddump command creates one or more dump levels in the dump
       hierarchy stored in the Backup Database, and optionally assigns an
       expiration date to each one. All of the dump levels in the Backup
       Database collectively constitute the dump hierarchy.

       Use the -expires argument to associate an expiration date with each
       dump level. When the Backup System subsequently creates a dump at the
       dump level, it uses the specified value to derive the dump’s expiration
       date, which it records on the label of the tape (or backup data file).
       The Backup System refuses to overwrite a tape until after the latest
       expiration date of any dump that the tape contains, unless the backup
       labeltape command is used to relabel the tape. If a dump level does not
       have an expiration date, the Backup System treats dumps created at the
       level as expired as soon as it creates them.

       (Note that the Backup System does not automatically remove a dump’s
       record from the Backup Database when the dump reaches its expiration
       date, but only if the tape that contains the dump is recycled or
       relabeled. To remove expired and other obsolete dump records, use the
       backup deletedump command.)

       Define either an absolute or relative expiration date:

       ·   An absolute expiration date defines the month/day/year (and,
           optionally, hour and minutes) at which a dump expires. If the
           expiration date predates the dump creation time, the Backup System
           immediately treats the dump as expired.

       ·   A relative date defines the number of years, months, or days (or a
           combination of the three) after the dump’s creation that it
           expires. When the Backup System creates a dump at the dump level,
           it calculates an actual expiration date by adding the relative date
           to the start time of the dump operation.


       -dump <dump level name>+
           Names each dump level to add to the dump hierarchy. Precede full
           dump level names with a slash (for example, "/full"). Indicate an
           incremental dump level by preceding it with an ordered list of the
           dump levels directly above it in the hierarchy (its parent dump
           levels); use the slash as a separator. The parent dump levels must
           already exist. For example, the dump levels "/full" and
           "/full/incremental1" must exist when the incremental dump level
           "/full/incremental1/incremental2" is created.

           Dump level names can have any number of levels, but cannot exceed
           256 characters in length, including the slashes. The maximum length
           for any single level (the text between slashes) is 28 characters,
           not including the preceding slash.

           All alphanumeric characters are allowed in dump level names. Do not
           use the period ("."), however, because it is the separator between
           the volume set name and dump level name in the dump name assigned
           automatically by the backup dump command. It is best not to include
           other metacharacters either; if using them, enclose them in double
           quotes (" ") when issuing the backup adddump command outside
           interactive mode.

       -expires <expiration date>+
           Defines the absolute or relative expiration date to associate with
           each dump level named by the -dump argument. Absolute expiration
           dates have the following format:

              [at] {NEVER | <mm>/<dd>/<yyyy> [<hh>:<MM>] }

           where the optional word at is followed either by the string
           "NEVER", which indicates that dumps created at the dump level never
           expire, or by a date value with a required portion (<mm> for month,
           <dd> for day, and <yyyy> for year) and an optional portion (<hh>
           for hours and <MM> for minutes).

           Omit the hh:MM portion to use the default of midnight (00:00
           hours), or provide a value in 24-hour format (for example, "20:30"
           is 8:30 p.m.).  Valid values for the year range from 1970 to 2037;
           higher values are not valid because the latest possible date in the
           standard UNIX representation is in February 2038. The command
           interpreter automatically reduces later dates to the maximum value.

           Relative expiration dates have the following format:

              [in] [<years>y] [<months>m] [<days>d]

           where the optional word in is followed by at least one of a number
           of years (maximum 9999) followed by the letter "y", a number of
           months (maximum 12) followed by the letter "m", or a number of days
           (maximum 31) followed by the letter "d". If providing more than one
           of the three, list them in the indicated order. If the date that
           results from adding the relative expiration value to a dump’s
           creation time is later than the latest possible date in the UNIX
           time representation, the Backup System automatically reduces it to
           that date.

           Constructs a server ticket using a key from the local
           /etc/openafs/server/KeyFile file. The backup command interpreter
           presents it to the Backup Server, Volume Server and VL Server
           during mutual authentication. Do not combine this flag with the
           -cell argument. For more details, see backup(8).

       -cell <cell name>
           Names the cell in which to run the command. Do not combine this
           argument with the -localauth flag. For more details, see backup(8).

           Prints the online help for this command. All other valid options
           are ignored.


       The following command defines a full dump called "/1999" with a
       relative expiration date of one year:

          % backup adddump -dump /1999 -expires in 1y

       The following command defines an incremental dump called
       "/sunday1/monday"1 with a relative expiration date of 13 days:

          % backup adddump -dump /sunday1/monday1 -expires in 13d

       The following command defines two dump incremental dump levels,
       "/Monthly/Week1" and "/Monthly/Week2". Their parent, the full dump
       level "/Monthly", must already exist. The expiration date for both
       levels is 12:00 a.m. on 1 January 2000.

          % backup adddump -dump /Monthly/Week1 /Monthly/Week2 -expires at 01/01/2000


       The issuer must be listed in the /etc/openafs/server/UserList file on
       every machine where the Backup Server is running, or must be logged
       onto a server machine as the local superuser "root" if the -localauth
       flag is included.
