A catalog backup consists of two parts:

  • Backup of the NetBackup database (NBDB)
  • Backup of data stored in files outside NBDB, such as a part of the image database, policy configuration, vault sessions, and various other configuration files.

An issue which was recently discovered affects the backup of data stored outside the NBDB (with the exception of image database files).  Files which have been newly created or modified since the last catalog backup may not be included in a differential incremental catalog backup.  Consequently, they would not be included in any restores taken from those backups.  This can lead to a restored environment which has a configuration which is not up to date; some configuration changes made after the previous full catalog backup may not be reflected after a restore.


The formal resolution for this issue (Etrack 2817226) is included in the following release:

Note: NetBackup 52x0 Appliances 2.5.1 is equivalent to NetBackup and includes the same resolution.  Information on this patch release is also available in a Related Article linked below.

A hotfix is now available for NetBackup in the Related Article linked below.

Do not use a differential incremental schedule for catalog backups.  Instead, use only full (and optionally, cumulative incremental) backup schedules with the NBU-Catalog policy type:

For NetBackup 5200/5220 Appliances 2.5, if the workaround above is unfeasible, please contact Veritas technical support, referencing this case and Etrack 2825685 to obtain a fix for this issue.

Fix availability may change.
