|
|
|
|
|

|
|
|
The B<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 C<.backup> extension on
|
|
|
|
the volume name if the backup version of the volume was dumped.

2005-12-13 19:21:13 +00:00
|
|
|
F</usr/afs/etc/KeyFile> file. The B<backup> command interpreter presents

it to the Backup Server, Volume Server and VL Server during mutual

|
|
authentication. Do not combine this flag with the B<-cell> argument. For

=head1 OUTPUT
|
|
|
|
|
|
|
|
The output includes a line for each Backup Database dump record that
|
2005-12-13 19:21:13 +00:00
|
|
|
mentions the specified volume, order from most to least recent. The output
|
|
|
|
for each record appears in a table with six columns:
|

|
|
=item dumpID
|
2005-12-08 12:14:33 +00:00
|
|
|
|
|
|
|
The dump ID of the dump that includes the volume.
|
|
|
|
|
2005-12-13 19:21:13 +00:00
|
|
|
=item lvl
|
2005-12-08 12:14:33 +00:00
|
|
|
|
|
|
|
The depth in the dump hierarchy of the dump level at which the volume was
|
2005-12-13 19:21:13 +00:00
|
|
|
dumped. A value of C<0> indicates a full dump. A value of C<1> or greater
|
|
|
|
indicates an incremental dump made at the specified depth in the dump
|
|
|
|
hierarchy.

|
|
|
|
2005-12-13 19:21:13 +00:00
|
|
|
The dump ID of the dump's parent dump. A value of C<0> indicates a full
|
|
|
|
dump, which has no parent; in this case, the value in the C<lvl> column is
|
|
|
|
also C<0>.

=item creation date
|
2005-12-08 12:14:33 +00:00
|
|
|
|
|
|
|
The date and time at which the Backup System started the dump operation
|
|
|
|
that created the dump.
|
|
|
|
|
2005-12-13 19:21:13 +00:00
|
|
|
=item clone date
|
2005-12-08 12:14:33 +00:00
|
|
|
|
|
|
|
For a backup or read-only volume, the time at which it was cloned from its
|
2005-12-13 19:21:13 +00:00
|
|
|
read/write source. For a read/write volume, the same as the value in the
|
|
|
|
C<creation date> field.
|
|
|
|
|
|
|
|
=item tape name
|
|
|
|
|
|
|
|
The name of the tape containing the dump: either the permanent tape name,
|
|
|
|
or an AFS tape name in the format
|
|
|
|
I<volume_set_name>.I<dump_level_name>.I<tape_index> where
|
|
|
|
I<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;
|
|
|
|
I<dump_level_name> is the name of the dump level at which the initial dump
|
|
|
|
was backed up; I<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.
