       backup_savedb - Creates a saved copy of the Backup Database


       backup savedb [-portoffset <TC port offset>]
           [-archive <date time>+] [-localauth]
           [-cell <cell name>] [-help]

       backup sa [-p <TC port offset>] [-a <date time>+]
           [-l] [-c <cell name>] [-h]


       The backup savedb command creates a backup copy of the entire Backup
       Database and writes it to the tape in the device controlled by the Tape
       Coordinator indicated with the -portoffset argument. If the database is
       damaged (as reported by the backup dbverify command), this command
       repairs as much of the corruption as possible as it creates the saved
       copy. The Backup Server creates a dump record for the saved database in
       the Backup Database (but in the disk version of the database only, not
       in the version written to tape).

       If the "FILE YES" instruction appears in the
       /var/lib/openafs/backup/CFG_device_name file associated with the
       specified port offset, then the backup savedb command dumps the
       database copy to the backup data file listed for that port offset in
       the Tape Coordinator’s /var/lib/openafs/backup/tapeconfig file, instead
       of to tape. For the sake of clarity, the following text refers to tapes
       only, but the Backup System handles backup data files in much the same

       If the -archive flag is provided, after writing the saved copy of the
       database the Backup System truncates the copy of the database on disk
       by deleting volume dump records with timestamps prior to the specified
       date and time (it does not delete the dump records created by previous
       backup savedb commands, however).

       If the tape to which the database copy is written has an AFS tape name,
       it must be "Ubik_db_dump.1" or "<NULL>". Any permanent name is

       The Tape Coordinator’s default response to this command is to access
       the first tape by invoking the "MOUNT" instruction in the local
       /var/lib/openafs/backup/CFG_device_name file, or by prompting the
       backup operator to insert the tape if there is no "MOUNT" instruction.
       However, if the "AUTOQUERY NO" instruction appears in the
       CFG_device_name file, or if the issuer of the butc command included the
       -noautoquery flag, the Tape Coordinator instead expects the tape to be
       in the device already.  If it is not, the Tape Coordinator invokes the
       "MOUNT" instruction or prompts the operator. It also invokes the
       "MOUNT" instruction or prompts for any additional tapes needed to
       complete the operation; the backup operator must arrange to provide


       -portoffset <TC port offset>
           Specifies the port offset number of the Tape Coordinator handling
           the tapes for this operation.

       -archive <date time>+
           Specifies a date and time; volume dump records with earlier
           timestamps are deleted from the disk copy of the Backup Database
           after the Backup System dumps the database (a dump’s timestamp
           appears in the "created" field of the output from the backup
           dumpinfo command). However, if a dump set contains any dump created
           after the specified date, none of the dump records associated with
           the dump set are deleted. Dump records for previous dumps of the
           database (created with the backup savedb command) are never
           deleted; use the backup deletedump command to remove them.

           Provide one of two values:

           ·   The string "NOW" to indicate the current date and time, in
               which case the Backup System deletes all dump records except
               those for dumps of the Backup Database itself.

           ·   A date value in the format mm/dd/yyyy [hh:MM]. The month (mm),
               day (dd), and year (yyyy) are required, and 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 Backup System
               automatically reduces any later date to the maximum value.

               The hour and minutes (hh:MM) are optional, but if provided must
               be in 24-hour format (for example, the value "14:36" represents
               2:36 p.m.). If omitted, the time defaults to 59 seconds after
               midnight (00:00:59 hours). Similarly, the backup command
               interpreter automatically adds 59 seconds to any time value
               provided. In both cases, adding 59 seconds compensates for how
               the Backup Database and backup dumpinfo command represent dump
               creation times in hours and minutes only. That is, the Database
               records a creation timestamp of "20:55" for any dump created
               between 20:55:00 and 20:55:59. Automatically adding 59 seconds
               to a time thus includes the records for all dumps created
               during that minute.

           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 example writes a copy of the Backup Database to the tape
       device controlled by the Tape Coordinator with port offset 1:

          % backup savedb -portoffset 1


       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.
