Hello Wanda,

The current version of Data Protection for Exchange
does not manage the backups from different servers together.
The best practice in the book says:

   "Backups for a given database should be run from the
    same Exchange server, if possible. Backups performed from
    different Exchange servers are managed separately."


This is not ideal, we understand and have taken steps to make it better.

In the Data Protection for Exchange version 6.4 that will
be generally available this Friday (11/16), we have enhanced
the Exchange 2010 DAG support. We have resolved this limitation.
You will be able to back up your Exchange 2010 DAG databases
from any server and they will be managed as a single entity
on the TSM Server.

Thanks,

Del
