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.
