Backing Up (Unattended)
The unattended backup contains all of the information necessary to bring the
system back to an operational state after a service affecting event. However, the
unattended backup alone cannot completely restore the system to its previous
state. The unattended backup can only bring the system back to an operational
state. Employ the disaster recovery procedures outlined in Appendix D, ‘‘Disaster
Recovery Checklists’’, to restore a system to the previous state.
Unattended backups do not require supervision and occur automatically.
However, for the backup to be successful you must ensure that a cartridge tape
is in the tape drive.
Unattended backups occur nightly at 3:00 a.m. and may take up to four hours.
Unattended backups do not degrade service.
After verifying that the unattended backup was successful, remove the tape.
Label it (with date and backup data type, for example, System Data), and store it.
A second tape should then be inserted into the tape drive. See “Verifying the
Unattended Backup” below for backup verification procedures.
How to Manage Tapes
!
CAUTION:
Do not leave the same tape in the tape drive day after day. Once the
unattended backup begins, the previous day’s data is overwritten and
unretrievable. Should today’s unattended backup fail, neither today’s nor
yesterday’s data will be available.
In order to better manage the backed up data it is recommended that two tapes
be used.
These two tapes can be alternated daily or additional tapes may be used to
implement a longer cycle (for example, seven tapes labeled with the days of the
week).
What Data Is Backed Up
An unattended backup saves:
■ Detailed system data on shared memory, speech filesystem pointers, etc.
■ Alarm management information
■ A list of enabled features
■ A list of installed software
