Basic system procedures 4-9
Installation and Maintenance Standard 3.0 March 1994
Once you have entered a schedule, backups proceed automatically. You may
choose to leave the same tape in the drive at all times. New backup data will
overwrite the old backup data.
Note: A backup tape will wear out over time. Please ensure that you re-
place it regularly with a new tape, according to the manufacturer’s rec-
ommendations.
Scheduled backups are useful in the event of emergencies, but you should still
perform an immediate full system backup before proceeding with any signif-
icant hardware or software procedures to ensure that no data is lost.
Restoring the system
Should the system fail, a recent backup tape allows you to restore the system
to the point at which the backup was made.
1
Run the System Installation and Modification Utility from the Meridian
Mail software tape. (Refer to Chapter 2.)
Note: Always use the same software release that was used to create the backup.
Do not, for example, attempt to restore an MM8 system using an MM9 software
tape.
2 From the System Installation and Modification Menu, choose
“8 More Utilities” → “2 Restore System from Backup”.
3 At the prompt, insert the most recent full system backup tape you have
into the tape drive and press .
Note: The restore process takes approximately 40-80 minutes to complete.
4 At the prompt:
The operation successfully completed.
Please remove the tape and boot into service.
a. Remove the tape from the drive. (Refer to page 1-16.)
b. Turn off the power to Meridian Mail.
c. Wait ten seconds.
5 Start Meridian Mail. (Refer to page 4-6.)
The system starts up in full service as it was when the backup was creat-
ed.
