Error Reported By Registry - HP Data Protector A.06.11 Integration Manual

Figure 120 Error reported by registry
it means that the Windows registry is out of space.
If there are too many entries in the Windows system registry, the registry runs out of
space and consequently backup fails. Although Data Protector does not write anything
to registry directly, the registry contains entries about all volumes and disks ever
presented on the system recorded by the volume storage driver.
Action
The registry should be cleaned up. For information on how to clean the registry, see
the web page http://support.microsoft.com/kb/277222/en-us.
In case of problems with the installation of the Scrubber utility provided by Microsoft,
contact Microsoft Product Support Services.
It is recommended to perform registry management tasks periodically to prevent the
registry from filling.
Problem
Data Protector reports that a volume was not removed
During a backup session, the following error is reported:
Volume 'StorageID', which is part of backup 'backupID', was not removed.
This error may appear if a replica on the disk array is removed, but its entry in the
VSS database (VSSDB) remains intact.
This may happen when a backup session fails without creating a replica, but the
reference that was created for it could not be removed due to network problems.
Action
To remove the false entry from the VSSDB:
1. In the error messages, find the ID of the session which could not remove the
target volume.
