To restore files that were archived using a scripted backup, use the
restore script. Its usage is quite straightforward. In the
simplest form, invoke
restore --all, it will
then restore all the file systems and files specified in
‘backup-specs’ (see section BACKUP_DIRS).
You may select the file systems (and/or files) to restore by
restore a list of patterns in its command
line. For example, running
will restore all file systems on the machine ‘albert’. A more complicated example:
restore 'albert:*' '*:/var'
This command will restore all file systems on the machine ‘albert’ as well as ‘/var’ file system on all machines.
restore will start restoring files from the lowest
available dump level (usually zero) and will continue through
all available dump levels. There may be situations where such a
thorough restore is not necessary. For example, you may wish to
restore only files from the recent level one backup. To do so,
use ‘--level’ option, as shown in the example below:
The full list of options accepted by
Restore all file systems and files specified in ‘backup-specs’.
Start restoring from the given backup level, instead of the default 0.
Set verbosity level. The higher the level is, the more debugging information will be output during execution. Default level is 100, which means the highest debugging level.
Display short help message and exit.
Display information about the program’s name, version, origin and legal status, all on standard output, and then exit successfully.
You should start the restore script with the media containing the first volume of the archive mounted. The script will prompt for other volumes as they are needed. If the archive is on tape, you don’t need to rewind the tape to to its beginning—if the tape head is positioned past the beginning of the archive, the script will rewind the tape as needed. See section Tape Positions and Tape Marks, for a discussion of tape positioning.
Warning: The script will delete files from the active file system if they were not in the file system when the archive was made.
See section Using
tar to Perform Incremental Dumps, for an explanation of how the script makes
