Wait until TSM version 5 is available (end of April) as that will allow you
to do LAN free to disk as well as Tape under the same licence.  Therefore
you will be getting SANErgy for cheap.  This will allow you to backup your
SAN attached nodes to disk and then migrate the data to tape when the
drives are free.

No, we don't have a SAN now.  IBM is trying to sell us one.  I am just
looking
into ways to incorporate it into our existing configuration before making
a recommendation to my boss.  Our Exchange database is about
40G.  It is being backed up directly to tapes through the LAN to FC 3590E
tape drives in a 3494 and runs for 2 hours.
