HP Data Protector IDB Purge User Manual

Automated IDB purging done by the Daily Maintenance
What is the Daily Maintenance?
Daily Maintenance runs a series of commands that purge obsolete data from many sections of the DP
IDB. By default, the Daily Maintenance takes place at midday (12:00 Hrs.) each day. It does not
purge all parts of the IDB, just the parts that can be done without exclusive access to the IDB. (For
more information about this, see the Appendix A.)
Setting the time Daily Maintenance runs
The time the Daily Maintenance runs can be changed by the setting Daily Maintenance Time in the
global file.
The Daily Maintenance can be disabled by setting Daily Maintenance Time = 99:99 or None in the
global file.
Note:
Disabling daily maintenance is not recommended by Hewlett Packard,
unless alternative arrangements to maintain the DP IDB have been made.
Methods to confirm if, and when, Daily Maintenance is being run
Method 1
Look at the global file for the values of Daily Maintenance Time:
On Windows the file is (default) C:\Program Files\OmniBack\Config\Server\Options\global
On HP-UX the file is /etc/opt/omni/server/options/global
For example if you only see
# DailyMaintenanceTime=HH:MM daily maintenance is running at 12:00
If you see
DailyMaintenanceTime=99:99 daily maintenance is disabled
DailyMaintenanceTime=None daily maintenance is disabled
DailyMaintenanceTime=08:30 daily maintenance is running at 08:30
Method 2
Run the command omnicc -debug 20 CHECK.txt, and look at the output debug file which will:
• Be in (default)/tmp on HP-UX
• Be in (default) C:\Program Files\OmniBack\tmp on Windows
• Have file name ending with CHECK.txt.
