       backup_volinfo - Displays a volume’s dump history from the Backup


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

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


       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.


       -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.

           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 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:

           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.

           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.


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

          % backup volinfo -volume user.smith.backup
