Re: [Veritas-bu] Duplications running very slow
Hi Duplication is a restore + backup; if your duplication is slow, it´s very likely that the restore operation is the culprit (maybe because the MPX). If possible, try to backup to a disk. Restores (and dups) are so much faster using this kind of media. hth On 11/13/06, Delgado, Jess J CIV <[EMAIL PROTECTED]> wrote: Hi everyone, I've got a problem with our dupe's running very slowly.

Re: [Veritas-bu] Duplications running very slow
There was a known problem in 5.1 with duplication within the same storage unit. Just to see if this is hurting you (I have done this at my 18 different NB sites), create a new storage unit in your library called "duplication". Make it 1 drive, on demand only. (you don't have to lessen the number of concurrent drives in you other storage unit). Try a duplication (manual or vault) and pick "duplication" as the destination storage unit. See if things speed up.

I'm not sure how to check the MPX value, but I will look. The dupes are slow manual or vault. All the dest drives are superdlt. I've tried dupes from dlt700 to superdlt and superdlt to superdlt. The drives are direct connect (HVD SCSI) to the media server. When vaulting is going on or manual dupes, we don't see any slowdown or change in backups. Mostly it seems to just sit there, move a little data, then just sit there. Even if it's the only job running. Strange. Thanks for answering!
