The preferred method for performing
system disk backup and restore operations is to boot the operating system CD, choose
the DCL option from menu, and then enter the appropriate backup
commands. The detailed procedures are described in
Backing Up the System Disk and
Restoring the System Disk.
If you have an OpenVMS Cluster environment with
more than one system disk, be sure the volume label on each system
disk and backup copies of system disks are unique. Use the SET VOLUME/LABEL command
to change a volume label, if necessary.
