I've been working on resolving some troubles with Symantec Backup Exec 2010 R3 but haven't had much success. Our system is configured to backup to disk (Data Domain 630) then duplicate to LTO4 tape. Most jobs work, however I have the same couple of jobs that continue to fail on the duplicate job. We are 100% on our B2D process, but the duplicate jobs are a different story.
One server in particular backup job started at 7:14 PM and finished at 10:04 PM (~3 hours). Total size was 181 GB at a rate of 2.2 GB/min. This duplicate job started at 1:57 AM (following the backup) and failed at 2:02 AM (~5min). Before failing it backed up 4 GB at a rate of 1.8 GB/min. All jobs are created off a policy and I've located an article that tells me Symantec doesn't have a clue and there is no ETA on a resolution. I'm posting here to see if anyone has had success?
