When we've encountered these issues and the logs were no help, we had to narrow down the problem by creating multiple backups or streams. This approach allowed us to narrow down the culprit by eventually closing in on a bad file during the backup.

Here is where it gets strange. I've also tried creating a storage unit that uses /dev/null as it's basic disk pool. I've then set the backup policy to use this storage unit. This backup fails with the same error as if I use a storage unit and disk pool pointing to our data domain.

See if there is any storage (volume manager or disk I/O) related error/fault reported at the time of bpbkar failure. Also, you can try bpbkar null test - just to ensure that data can be read without any random read failures: bpbkar -nocont <failed_to_backup_path> > /dev/null Hope that helps, /Girish --- On Fri, 5/6/11, jim.ca...@mylan.com <jim.ca...@mylan.com> wrote: > From: jim.ca...@mylan.com <jim.ca...@mylan.com> > Subject: [Veritas-bu] NetBackup 7.1 media server backup issue > To: veritas-bu@mailman.eng.auburn.edu > Date: Friday, May 6, 2011, 6:45 AM > > Hi All, > > We're having a strange problem when the media server (AIX > 6.1) is backing > up itself.
