 5.6 Using the Restore Script
 ============================
 
 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' ( BACKUP_DIRS
 General-Purpose Variables.).
 
    You may select the file systems (and/or files) to restore by giving
 `restore' a list of "patterns" in its command line.  For example,
 running
 
      restore 'albert:*'
 
 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.
 
    By default `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:
 
      restore --level=1
 
    The full list of options accepted by `restore' follows:
 
 `-a'
 `--all'
      Restore all file systems and files specified in `backup-specs'.
 
 `-l LEVEL'
 `--level=LEVEL'
      Start restoring from the given backup level, instead of the
      default 0.
 
 `-v[LEVEL]'
 `--verbose[=LEVEL]'
      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.
 
 `-h'
 `--help'
      Display short help message and exit.
 
 `-V'
 `--version'
      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.   Tape Positioning, 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.
 
     Incremental Dumps, for an explanation of how the script makes
 that determination.
