I setup deduplication (2010 R3 all updates) no problem, and a backup job ran for about 50 hours and failed because on one server, the backup exec media server (Final error: 0xe000fed1 - A failure occurred querying the Writer status.Final error category: Resource Errors).

So 50 hours and failed because one server out of many.

The real problem is though that when I reran the job I get an error:

(failed Final error: 0xe000810c - Physical Volume Library Drive not available.Final error category: Backup Device Errors

How can it be not available and if I right click on the online is checked but greyed out. I restarted the server, havent changed anything.

(btw, anyone know of any good alternatives to backupexec, too many bugs).

Thanks.
