Commands Reference, Volume 4
Restores files from a backup source.
restorevgfiles [ -b
blocks ] [ -f
device ] [ -a ] [ -s ] [ -d path ] [ -D ] [ file_list ]
The restorevgfiles command restores files from tape, file,
CD-ROM, or their volume group backup source. The
restorevgfiles command also works for multi-volume backups such as
multiple CDs, DVDs, or tapes.
The restorevgfiles and listvgbackup -r commands
perform identical operations and should be considered interchangeable.
The restorevgfiles command automatically applies the -r
flag. The -r flag, while redundant, is retained for
compatibility purposes and will cause no unusual behavior if specified.
For a complete description of the -r flag, see the listvgbackup command.
-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.
|
-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. 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.
