Logical volume logical volumes
File/Directory directories, files
When restoring a volume group, all logical volume and filesystem data within the
volume group is restored. When restoring directories, all files within the directories
are restored as well, even if the files are contained in different filesystems.
The data argument can be a list of either volume groups, filesystems, logical
volumes, directories, or files, depending on the type of data to be listed, verified,
or restored (as indicated by the -t flag).
The -t option must be specified to indicate the type of data to verify or restore. For
instance, a volume group backup can contain multiple volume groups, filesystems,
and raw logical volumes. To restore two specific filesystems from the backup, you
must specify the -tF option, and the data argument at the end of the backup must
contain the mount points of the filesystems to restore. To restore only a specific
directory from a backup, regardless of the backup type, you must specify the -tD
option, and the data argument must be the directory or directories to restore.
To verify the backup by reading the data, specify the -V flag. When specified, the
data on the backup is read but no data is restored. You still need to specify the
type and data you want to verify. For example, to verify only a couple of raw
logical volumes on a volume group backup, specify the -V flag, the -tL option, and
the names of the logical volumes to verify as the data argument. To verify the
entire contents of a System backup, you must specify the -V flag, the -tV flag, and
the names of all volume groups to verify.
The -L flag is used to list the contents of the backup, depending on the type
specified with the -t flag. The following table indicates the data list that is created
with the -L flag, based on the type:
type (-t) Produces list of:
V Volume groups
L Logical volumes
F Filesystems
D Directories
R Regular files
f Directories and regular files
l Filesystems and logical volumes
The -T flag queries the type of backup and returns a single character as follows:
S System backup
P Power system backup
V Volume group backup
F Filesystem backup
L Logical volume backup
D File/directory Backup
