Standalone Backup Qualifiers - DEC MicroVAX 3100 Owner's Manual

DIGITAL recommends that you use standalone BACKUP, which uses a
subset of Backup Utility qualifiers, to back up and restore the system
disk. It is especially important that you understand the functions of the
!IMAGE and /PHYSICAL qualifiers to the BACKUP command before using

G.2.1 Backing Up the System Disk
To back up the system disk, use the following procedure:
1. Decide whether you want to back up the system to another fixed disk or
to a tape cartridge. If you are using a tape cartridge, obtain a scratch
tape that you can use for the backup copy. A scratch tape cartridge is a
tape cartridge that is either blank or contains files that you no longer
need.
2. If you are using a tape cartridge, write-enable it. To write-enable
a tape-cartridge, slide the write-protect switch away from the tape
cartridge label. Insert the tape cartridge in the tape cartridge drive.
3. Determine the device name of the drive holding the system disk and
the drive holding the backup disk or tape cartridge. Enter the show
device command at the console prompt (»».
4. Boot standalone BACKUP as described in Section G.1.2 or
Section G.1.4.
