This appendix describes how to perform backup and restore
operations on the system disk. You perform these tasks by entering
commands from a specialized backup environment. You access this
environment through the menu that is displayed when you boot the
OpenVMS I64 OE DVD, or through an alternative method that does not
require the DVD.
This specialized backup environment is required because it
allows you to create an exact copy of the system disk. You cannot
create an exact copy in a standard operating system environment
because the OpenVMS Backup utility saves only what is on the disk
at the moment the BACKUP command is executing, excluding portions
of open files contained in memory or data about files not yet written
back to the disk (cache).
For more information
about backup operations, including procedures for backing up and
restoring files and directories, refer to the HP OpenVMS System Manager's Manual, Volume 1: Essentials.
