Commands Reference, Volume 3
Lists or restores the contents of a volume group backup on a specified
media.
listvgbackup [ -b
blocks ] [ -f
device ] [ -r ] [ -a ] [ -s ] [ -d path ] [ -D ] [ file_list ]
The listvgbackup command lists the contents of a volume group
backup from tape, file, CD-ROM, or other source and can be used to restore
files from a valid backup source. The listvgbackup command
also works for multi-volume backups such as multiple CDs, DVDs, or
tapes.
The listvgbackup -r and restorevgfiles commands
perform identical operations and should be considered interchangeable.
-b blocks
| Specifies the number of 512-byte blocks to read in a single input
operation, as defined by the blocks parameter. If the
blocks parameter is not specified, the number of blocks read will
default to 100.
|
-f device
| Specifies the type of device containing the backup (file, tape, CD-ROM,
or other source) as defined by the device parameter. When
-f is not specified, device will default to
/dev/rmt0.
|
-r
| Specifies to restore the backup files, as defined by the
file-list parameter. If the file-list parameter
is not specified, then all files in the backup will be restored. If the
-r flag is not used, then executing the listvgbackup
command only lists the files in the specified backup.
|
-a
| Verifies the physical block size of the tape backup, as specified by the
-b block flag. You may need to alter the block
size if necessary to read the backup. The -a flag is valid
only when a tape backup is used.
|
-s
| Specifies that the backup source is a user volume group and not
rootvg.
|
-d path
| Specifies the directory path to which the files will be restored, as
defined by the path parameter. If the -d
parameter is not used, the current working directory is used. This can
be a problem if the current working directory is root. We recommend
writing to a temporary folder instead of to root.
|
-D
| Produces debug output.
|
file_list
| Identifies the list of files to be restored. This parameter is
used only when the -r flag is specified. The full path of
the files relative to the current directory should be specified in the
space-separated list. All files in the specified directory will be
restored unless otherwise directed. If you are restoring all files in a
directory, we recommend writing to a temporary folder instead of to
root.
