BACKUP

   Invokes the Backup utility (BACKUP) to perform the following
   BACKUP operations:

   o  Make copies of disk files.

   o  Save disk files to a BACKUP save set.

   o  Restore files from a BACKUP save set to disk.

   o  Compare disk files with other disk files or files in a BACKUP
      save set.

   o  List information about the files in a BACKUP save set.

   o  Create and list BACKUP journal files.

   The two ways to back up your system disk are:

   o  If you have access to the CD-ROM for the current version of
      OpenVMS Alpha, Integrity servers, or VAX, you can use the menu
      system supplied on the CD-ROM to back up your system disk.

   o  If you do not have access to the CD-ROM for the current
      version of OpenVMS VAX, you must use standalone BACKUP to
      back up your system disk (VAX only). Standalone BACKUP is
      a form of the Backup utility (VAX only) that you boot into
      main memory (instead of executing under the control of the
      operating system).

   For more information about BACKUP and standalone BACKUP tasks,
   see the VSI OpenVMS System Manager's Manual.
