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

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 CW.backup extension on the volume name if the backup version of the volume was dumped.

Names the volume for which to display the dump history. Include the CW.backup or CW.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 the backup(8) manpage. Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see the backup(8) manpage. 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. The depth in the dump hierarchy of the dump level at which the volume was dumped. A value of CW0 indicates a full dump. A value of CW1 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 CW0 indicates a full dump, which has no parent; in this case, the value in the CWlvl column is also CW0. The date and time at which the Backup System started the dump operation that created the dump. 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 CWcreation date field. 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 CWuser.smith.backup:

   % backup volinfo -volume user.smith.backup
