Hi Curtis,

what is the value of the TCPWINDOWSIZE parameter in the dsm.opt? According
to Tivoli for Windows NT it shouldn't be greater than 63 (KB). Other values
aren't supported by NT and would cause the TSM client to use the default
value of 32.

And another thing you can look for (in the dsmsched.log): Do you have set
serialization (in the backup copy groups) set to Shared Static or Shared
Dynamic? If you have and there are many retries during the backup that
could explain the poor backup performance.

My last tip: look for the network data transfer rate of the scheduled
client backup. If it is low and the network transfer time is high it could
mean that you have some network problems (and not necesseraly with TSM). On
the other hand a high network data transfer rate would rather indicate a
local client problem.

Mit freundlichen Grüßen,
Met vriendelijke groeten,
With best regards,
Bien amicalement,

CU/2,
