If you are using TDP for Exchange to perform your backups,
you can either run with "TSM" compression ON or OFF.
(That is the "COMPRESSION" option in the DSM.OPT file.)

If you run a backup with COMPRESSION ON, you have the typical
scenario of less data sent across the network and less
data stored on the storage device but more CPU for
the compression and usually longer backup elapsed
times due to the additional time for software compression.

But the bottom line to your question is that you
can run with COMRPESSION on or off.  It will work
both ways.

Thanks,
