Section 8 F Backing Up, Restoring, and De-Installing Software

Installing and Upgrading ENVOX

Configuration Software on DEC VAX and DEC AXP Systems (Revision B — May 1998)

8.4 Restoring the System

Always backup and restore together all disks which contain

ENVOX logical devices; do not reboot the system or allow the

SYBASE SQL Server to restart during a backup or restore

period. The logical device files contain information which must

always be kept in step. If they are not, the ENVOX database

can lose data. When you perform a backup or restore, always

make sure that you have a tape or tapes for each disk, and

keep the tapes together as a matched set.

Caution ...

For many reasons, you may need to restore your software system. You

should make backup copies of your system any time you make a change

to the database or a change to any other system software parameters.

Refer to subsection 8.3 for backup procedures.

Perform the following to restore the system:

Step 1: Boot standalone backup as described in subsection 8.1 for

VAX systems or subsection 8 .2 for AXP systems.

Step 2: Insert and load the first tape that holds your system b ackup.

When the tape is ready, enter the following command,

substituting the appropriate system device name for tapedrive

and the appropriate disk drive name for diskdrive (leave single

spaces after verify and rewind):

$ BACKUP/IMAGE/VERIFY tapedrive:saveset.BCK/REWIND diskdrive:

The following message is displayed:

%BACKUP-I-STARTVERIFY, starting verification pass

If you have only one tape to restore, go to Step 4; otherwise

continue with Step 3.
