Your original post of actlog stats didn't include how many objects
inspected/backed up.  If you have a LOT of small files that would
account for some of it.

What type of network do you have?

I just looked at some of my stats and I have on the clients I checked
a Network to Aggregate data transfer time of 2 -1 to 3 -1.

How many sessions does the client use?  You can set 
RESOURCEUTILIZATION in dsm.sys on client to increase number
 of sessions - see docs for info.  Experiment to see best for you.

I would think you can get better than 8 hours for 70GB.  I imagine
4 -6 hours is as good as you can  do.

Have TSM 3.7.4.0 server on AIX 4.3.3 on F50 with 4x 332Mhz CPU
and 2 GB RAM.  IBM 3575 library.  Using 155MB ATM network.  (Some clients have 
100MB Ethernet.)

The only client we have is where the server is located.  We are running TSM
to backup one RS/6000 F50 server.  And backing up 70 GB in 8 hours doesn't
seem right.  Is there anything that I can do to speed this up.  We run a
Magstar 3570 connected to the F50 server through SCSI.

TSM Version 4.1.2.0
AIX Version 4.3.3.0
