This is some benchmarks that I had run.

TSM / ArcServer Backup-Restore Comparison

Test server:    Compaq 7000
                Pentium Pro 200
                Ram 1703 Meg.
                Test volume on the ESS (Shark)


Original restore from FHNW108 to FHNW950 12.4 gig 7 hours 1.77 gig/hour. I
restored this to 2 different locations. For a total of 24.8 gigs plus
another volume for a total of 26.2 gigs.

The Backup test used both ArcServe and TSM.

TSM results 338,961 files 25.4 gig in 5 hours 15 minutes, 4.83 gig/hour.

ArcServe results 313,058 26.2 gig in 8 hours, 3.27 gig/hour



The Restore test used both ArcServe and TSM.

TSM results from recent backup 329,721 files 25.36 gig in 4 hours 25
minutes, 5.74 gig/hr
TSM results from old backup 166,084 files 11.78 gig in 4 hours 45 minutes,
2.48 gig/hr

ArcServer results 313058 files 26.229 meg of data restored in 8 hour 36
minutes, 3.05 gig/hour.

Subject:        Restore Throughput

I'm just looking for any guesstimates anyone might have for the throughput
we might "expect" to see restoring a Netware 3.1.08 client with a TSM
3.7.3.0 OS/390 server.  This is over a 100M ethernet with 3490 tape robot on
the server.  We have split the restore up over 4 sessions and have disabled
any other TSM processing while we run the restore.

We are seeing about 1.2G an hour actual data being restored.  Can anyone say
whether this is about what we should expect?  I have been in contact with
Tivoli and tuned the client and server options per their instructions.  I
was wondering if anyone had any idea if this seems a reasonable rate.

Thanks for any input.
