> Hello list. I have a brand new database that is around 200 GB in

> company is only giving me bewteen 6 and 7 MB per second . A full cold
> backup can take 8 to 10 hours at this rate.

> I looked at the specs for the tape library they sold us and it says
> 15MB/sec or up to 30 MB/sec compressed. What gives? The storage is
> SCSI 3 and also some Fibre channel so I don't think the drives are the
> bottleneck.

> What kind of numbers are other people getting?

> The system
> NT 4
> 4GB RAM
> 400 GB storage (mix of SCSI 3 and fibre)
> Oracle 8.1.6.3.0
