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)

8.3 Backing Up 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 ...

Once your computer system is ready for use, you should make a backup

copy of the software. This backup allows you to restore the software

quickly, in case of any unplanned change.

Perform the following to back up 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 tape on which you want to save the

software and data from the hard disk. This tape must not be

write protected. When the tape is ready, enter the following

command (leave single spaces after noassist and

systemdisk:):

$ BACKUP/IMAGE/VERIFY/NOASSIST systemdisk: tapedrive:saveset.BCK/SAVE/REWIND/IGNORE=LABEL

where systemdisk is the n ame of the drive holding the system

disk and tapedrive is the name of the drive which will hold the

backup files. For saveset, substitute a valid (1 3 characters

maximum) name for the saved data.
