I have tried the ftp and can transfer 500 meg in 45 seconds which is 9.7
MB/sec. So it does appear to be TSM that is responding slowly.

Test FTP throughput from client to server. Compare to backup speed. What
are the number of files backing up?
Is the 2 Meg/sec network transfer of aggregate?
You can get up to 131 Gigs/hour using client compression. It all depends
on
what the client, server, and network design are.

In the first place, drop the compression. Compression is only
intended for
slow links where the amount of data sent over the wire is impotant.
It is a
huge CPU burden for the client to compress the data, so high
transfer rates
are not possible with it enabled.
Personaly I would say that any line above 2Mbits/s should not use
compression.
Just MHO,
