Hi all. I test NDMP backup performance for a particular storage appliance, which involves writing and running scripts that perform backup and restorations, using up to ten tape drives across two different tape libraries at a time. These scripts use...

cruisen, the tape libraries are directly connected to our storage appliance via Fibre Channel, which is seen in NBU as an NDMP host. In this circumstance, I'm backing up from the appliance to tape, then trying to restore back to the same storage app...

Hmmm, thanks, Marianne. I wouldn't say the jobs are "stuck at" media needed, as the first job immediately gets its tape, and when its done, the second job gets its tape. The pointer to the bprd log seems helpful - here's what I see when I run my t...

Michal, the jobs are each kicked off with a separate command. Each job runs a different policy for a different mountpoint. I'm testing for a storage appliance manufacturer, so I know there are no restrictions from that end, either as a disk target,...

I created 10 new volume pools, assigned a tape to each pool (paying attention to what tapes are in which library) and kicked off my test again. Once again, all 10 tape drives got used for writing the backup, but the restore jobs are happening serial...

Will, I've had multiple restore jobs running to the same client simultaneously before on other installations, so I don't think there are any design constraints that I'm running into. The jobs back up completely different filesystems, so limiting the...
