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
theDVD.
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,
see the HP OpenVMS System Manager's Manual, Volume 1: Essentials.
