Paul,
I know it's been a while since you posted this but I wanted to share my
insights. We've received the same complaints.
The problem is not TSM per se, but the fact that I/O is interrupt-based
and the interrupt service routines run at high-priority. This also
affects any scan process, includ
thnx!!

Paul,
If the tsm clients are running under linux, you could use CBQ (Class
Based Queueing) to perform traffic shapping on the output traffic of
the nic. This works pretty well.
Google for CBQ Linux. .

Thanks Richard, et al,
I thought the default RESOURCEUTIL was also the minimal value, so I
don't think we could lower that any more than it already is. Using
MEMORYEFFICIENTBACKUP is a good idea, as is using 'nice' to deprioritize.

Turn on client-side compression so you monopolize their cpu instead?
Sorry, couldn't resist. You have a problem some of us wish we had.
Usually the filesystem scanning takes long enough that it creates pauses
in the use of the nic (at least here). You might be able to

Certainly, "de-tuning" the TSM backups will reduce the impact, where
the most obvious tactic is to minimize RESOURceutilization. And you
can get more drastic via MEMORYEFficientbackup Yes. Depending upon

We have a small number of users here who are complaining that when a
TSM backup runs on their client system, it monopolizes use of their
network card. They are looking for a way to throttle back TSM's use
of the network. Has anyone else run into this? Any ideas? The only
