NAME

       backup_volinfo - Displays a volume's dump history from the Backup Database

SYNOPSIS

       backup volinfo -volume <volume name> [-localauth]
           [-cell <cell name>] [-help]

       backup voli -v <volume name>
           [-l] [-c <cell name>] [-h]

DESCRIPTION

       The backup volinfo command displays a dump history of the specified volume, reporting
       information such as the date on which the volume was dumped and the tapes that contain it.
       Include the ".backup" extension on the volume name if the backup version of the volume was
       dumped.

OPTIONS

       -volume <volume name>
           Names the volume for which to display the dump history. Include the ".backup" or
           ".readonly" extension if the backup or read-only version of the volume was dumped.

       -localauth
           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).

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

OUTPUT

       The output includes a line for each Backup Database dump record that mentions the
       specified volume, order from most to least recent. The output for each record appears in a
       table with six columns:

       dumpID
           The dump ID of the dump that includes the volume.

       lvl The depth in the dump hierarchy of the dump level at which the volume was dumped. A
           value of 0 indicates a full dump. A value of 1 or greater indicates an incremental
           dump made at the specified depth in the dump hierarchy.

       parentid
           The dump ID of the dump's parent dump. A value of 0 indicates a full dump, which has
           no parent; in this case, the value in the "lvl" column is also 0.

       creation date
           The date and time at which the Backup System started the dump operation that created
           the dump.

       clone date
           For a backup or read-only volume, the time at which it was cloned from its read/write
           source. For a read/write volume, the same as the value in the "creation date" field.

       tape name
           The name of the tape containing the dump: either the permanent tape name, or an AFS
           tape name in the format volume_set_name.dump_level_name.tape_index where
           volume_set_name is the name of the volume set associated with the initial dump in the
           dump set of which this tape is a part; dump_level_name is the name of the dump level
           at which the initial dump was backed up; tape_index is the ordinal of the tape in the
           dump set. Either type of name can be followed by a dump ID in parentheses; if it
           appears, it is the dump ID of the initial dump in the dump set to which this appended
           dump belongs.

EXAMPLES

       The following example shows part of the dump history of the Backup volume
       "user.smith.backup":

          % backup volinfo -volume user.smith.backup
          DumpID    lvl parentID  creation date    clone date       tape name
          924600000 1   924427600 04/20/1999 05:20 04/20/1999 05:01 user_incr_2 (924514392)
