Sal,

The level of granularity for Exchange backups is at the
Storage Group level. That means you can run backups
of separate Storage Groups simultaneously.
For example:
   start tdpexcc backup SG1 full
   start tdpexcc backup SG2 full
   start tdpexcc backup SG3 full
   start tdpexcc backup SG4 full

However, I am guessing that a single instance backup over a
WAN is probably more than enough to saturate the available bandwidth.

FWIW, running a full backup to a TSM Server that takes over a week
is something you want to avoid since it probably wreaks havoc on
the TSM Server transaction log. You may want to look at alternatives
like getting a higher bandwidth connection or creating a
TSM Server local to the Exchange server itself.

Thanks,

Del
