11Using BACKUP  



You can guard against data loss or corruption by using the OpenVMS Backup utility (BACKUP) to create copies of your files, directories, and disks. In case of a problem--for example, a disk drive failure--you can restore the backup copy and continue your work with minimal disruption.
