HP Data Protector IDB Purge Best Practices

Appendix D

Failed_copies purge

Note:

This purge is available by default on DP 6.1 and 6.11, but for DP 6.0 it

requires one of the following patches, or their successor.

Table 5.

Windows HP-UX PA Risc HP-UX IA 64

In certain circumstances a DP IDB may hold multiple copies of failed objects made during a backup.

These multiple copies of failed objects may overload an IDB. A special purge, omnidbutil -

purge_failed_copies, removes any failed objects that are not the original from the IDB.

DP 6.1 and 6.11 by default, and DP 6.0 with one of the patches above, have two additional

functions with respect to these multiple unrequired copies of objects. They allow the running of

omnidbutil -purge_failed_copies and they correct the behavior that caused the multiple

copies of objects. For these reasons once this command has been run it should rarely need repeating.

The command requires exclusive access to the IDB so can only be run when no backups are running

and all GUIs are closed.

When run, this purge updates the RDS.log file.

• On Windows the RDS.log file is, by default,

C:\Program Files\OmniBack\db40\datafiles\catalog

• On HP-UX the debug.log file is: /var/opt/omni/log

Example of messages seen at the command line
