Under certain conditions, when deleting and adding schedules to an existing synthetic backup policy, the file list for the newly added schedule may be incomplete. This can lead to the appearance of successful backups (status code 0 reported in the Activity Monitor) but upon attempt to restore, the backup is found to be incomplete.
The formal resolution for this issue (Etrack 3383898) is included in the following release:
- NetBackup 7.6 Maintenance Release 2 (22.214.171.124)
This release is now available - more information can be found in the Related Article linked below.
If this issue is experienced, please contact Symantec technical support, referencing this document ID and one of the following Etracks to obtain an Emergency Engineering Binary (EEB) replacement for nbjm which contains a fix for this issue:
- 126.96.36.199: 3387635
- 188.8.131.52: 3387634
Note that while this EEB will prevent future occurrences of this issue, any previously affected backups will remain incomplete.
