A suggestion for a workaround:

Put a managed TSM server in the same LAN as your Exchange boxes. Give
the new TSM server enough diskpool to back up the information store
and database for the Exchange servers without the immediate use of a
tape pool spillover. 

Set an administrative scheduled event to flush the diskpool to the
library attached to your local TSM server for a time which will have
less business impact (i.e., 0130 local time).
