Commands Reference, Volume 4
restorevgfiles Command
Purpose
Restores files from a backup source.
Syntax
restorevgfiles [ -b blocks ] [ -f device ] [ -a ] [ -s ] [ -d path ] [ -D ] [ file_list ]
Description
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.
Flags
-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. |
Parameters
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. |
Examples
- To read the backup stored at /dev/cd1 and restore
all files to the /data/myfiles directory, enter:
restorevgfiles -f /dev/cd1 -s -d /data/myfiles
- To read the user vg backup from the default device at 20 512-byte blocks
at a time and restore the /myapp/app.h file to the current
directory, enter:
restorevgfiles -b 20 -s .myapp/app.h
- To read the backup stored at /dev/cd1 and restore
the /myapp/app.c file to the /data/testcode directory, enter:
restorevgfiles -f /dev/cd1 -s -d /data/testcode ./myapp/app.c
