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.
See Guidelines for OpenVMS Cluster Configurations
for
information about using BACKUP when your backup medium is connected
to a Fibre Channel interconnect.
