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).

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 0 indicates a full dump. A value of 1 or greater
indicates an incremental dump made at the specified depth in the dump
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
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
"creation 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 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.
