Just a heads-up for those of you running NBU 6 who have backup jobs that mysteriously do not run: There is apparently a known issue with checkpoint-enabled backups and the "pempersist" file.
The scenario is this: If you have a backup policy with checkpoints enabled, and a job in that policy fails for any reason (even if it retries successfully), that job will be listed in the pempersist file as "active", and it will never again run automatically. Manual starts will work fine.
Two work-arounds:
1. Turn off checkpoints. Or,
2. Delete the pempersist file every day: Make sure no jobs are running (i.e., all jobs are "Done"), stop all NBU services, delete %INSTALLPATH%\VERITAS\NetBackup\bin\bpsched.d\pempersist, then restart all NBU services. Do this every day (or at least every day you had a backup failure).
My ticket with Symantec is still open; we're collecting logs (including the output of "nbpemreq -tables screen" - another undocumented command), and we may eventually get a fix from engineering (or will have to wait until MP3).
FYI.
