Just to recap, 

Network = 1G that means max 80GB/s towards the server. 
San to S-AIT(234?) what is the max speed there both comressed and uncompressed 
(can be tested with a local large file)
What kind of clients also 1G net, what kind of data (large files, many small) 

All those factors influence the client speed and therefore the backup speed.

In my environment  Sol9 E450 2x400Mhz CPU 1 GB mem, I see the highest 
throughput on cloning as that does not use any network at all. LTO-2 on 
LSi320 scsi gives me 40M/sec on average while normal backups vary strongly 
according to the data on the client but (as my network is basically 100M full 
duplex) never more than 10M/sec.

Hope this helps a bit,

Maarten
