Slow tape backup BE2008 R3 to Quantum SuperLoader3
Something has degraded on the new Windows 2008 R3 media server that I've built recently. We've just had the Quantum SuperLoader 3A replaced by Quantum as it was generating errors. But I wonder if that is just coincidence as the new unit is hobbling along at ~100MB/min whereas this same tape unit has managed over 800MB/min before.
Considering this is a new unit, I wanted to remove the hardware from the equation so I've taken an image of the Windows 2008 media server and just installed plain-vanilla Windows 2003 R2 x64 with Quantum drivers. The reason I installed Windows 2003 so I could try a raw backup with NT Backup (which has been removed from Windows 2008).
On this plain system, the tape drive backed up 15GB (from local hard drive) in 8 minutes 4 seconds which is 1,917MB/min which a) shows the drive is working fine and b) gives a good indication what speed the LTO-3 drive is capabable of.
I'm just back to put the original media server image back on there (so we can do monthly backup) but just wondered if anyone has any ideas in the meatime why we're only getting 20th of the speed of NT Backup?
