If a backup policy is configured to use the TIR (True Image Restoration) feature, NetBackup saves additional file and directory metadata from each client in all incremental backup images that are created by the policy.
Image cleanup will remove ("prune") the additional metadata from older incremental backup image files in the catalog after the policy has run a new full backup of the client and after the number of days indicated by the Keep true image restoration (TIR) information setting in the Clean-Up section of the master server Host Properties have elapsed.
Under NetBackup 220.127.116.11, this data "pruning" operation fails. It normally fails silently, but on some master servers the failure may also result in error messages being logged in the NetBackup error report.
The consequence of this failure is that the amount of data in the catalog will grow faster than expected. The rate of growth depends on the number of backup policies that are configured to use TIR, and the number of files that are protected by the policies configured to use TIR. In some situations, the failure to remove this additional data may result in the disk that holds the image catalog becoming full.
The following error message MAY be logged in the NetBackup All Log Entries report:
08/07/2013 13:06:04 nbmaster.mydomain.com - can not decompress file -
events out of sequence - image inconsistency (229)
Note: The absence of this error message does NOT mean that the problem does not exist.
An incorrect SQL query performed by bpdbm's TIR data pruning operation returns invalid data.

NetBackup 52x0 Appliances 2.5.3:
Please download the RPM attached below and access the Related Article linked below for instructions on applying the hotfix on an Appliance.
Note: After this hotfix is applied, the first image cleanup job may run for a much longer time than normal. This would be expected due to the large number of backup images which need to have old TIR data pruned from their image files in the catalog on disk.
Any master server running NetBackup 126.96.36.199 which has one or more backup policies configured to use the TIR option (either with or without move detection). No other versions of NetBackup are affected by this problem.
