I've recently built a new media server and attached our Quantum Superloader 3 (LTO3) via an Adaptec SCSI card. I'm pretty sure it's starting to fail as I'm sure we got much better throughput when we first re-attached it. It's also throwing up worrying "clean me" reports more often than it should.
However, before I call Quantum support, just wanted to check what's the rough throughput one would expect from a LTO3 tape drive. The test backup is writing a B2D BKF 4GB file to tape where the BKF is local (so no network involved). It's struggling at 78MB/min when I'm sure it should be a factor of 10 times faster. This is basically streaming a 4GB compressed file straight to tape.
We've lost old catalog/job logs so cannot check back.
Cheers, Rob.
PS. Can one use Windows backup on the same server as a test?
