Paul -

In Unix, at least, a less important process (the backup, in this case)
can be "reniced" to reduce its impact, giving the more important
processes a higher relative priority in accessing resources. There may
be a similar mechanism for Windows.

Incremental backups have a considerable impact because of the Active
Files list they have to juggle. You could evaluate whether a
-INCRBYDate type backup would be viable for the involved systems, where
there is no list overhead.

Thanks for the suggestions so far.  I should have mentioned that this
is
for an application server who's performance is important 24x7.  We do
already schedule during off-peak, but even so the performance
degradation
caused by the TSM backup is noticed and is perceived as a problem.
