Duplicate B2D to tape is VERY slow

I am testing the B2D functionality and the duplicate to tape so I can use backup to disk rather than backup to tape.

Backping up to tape directly from disk though a backup job --> Very fast.

But if I set up a policy to backup to disk then duplicate to tape --> The speed from disk to tape using the policy method backs up at less that 10% of the speed of backup straight to tape.

I even did a backup of the .bkf (regular backup) and it runs very fast.

Has anyone else experienced this bad performance and has anyone been able to solve it? I have not called symantec yet, but was curious if others had the same issue.

Thanks in advance for any info

  • Is the tape device on it's own SCSI controller? or at the very least it's own channel?

    or is it sharing a channel with the disk drive?

  • Hi David, did you resolve this issue? I have always had similar problems with duplicate jobs - they're very slow.
