And what kind of files?  Average file size?  Just as a point of reference, I
can back up >1 GB per minute with a similar master server and STK9840B tape
drives.  This is for very large compacted files, of course.  For normal
generic server backups, I usually see 600-1200KB/sec.

How many streams are you running simultaneously and to what kind/model of
tape drive?

I was just wondering how long backup times are taking for everybody. It is
currently taking us about 10 hours to back up 50GB of data which seems to be
a very long time. The servers are dual PII 450 processors with over 2GB of
memory running Windows 2000 Advanced Server. Nics are locked down at
100/full and I have increased the size and number of data buffers so I am
just curious as to if this is normal.

If anyone has any benchmarks it would be appreciated.
