Wanda, it looks like this is fixed in the TSM 6.4 TDP-E. This is from the IUG.
You can back up Exchange Server Database Availability Group (DAG) servers by using a common policy. By coordinating backups between DAG servers, you can prevent duplicate or redundant backups. The following features are available for DAG environments. - Back up DAG databases to a common node. The backups can be managed by a single policy regardless of which DAG member (server) performed the backup. - Coordinate backups between DAG members so only one copy is backed up per backup cycle. - Reduce the load on the production Exchange server in a DAG by setting a preference for backing up a healthy passive database copy unless no healthy passive copy is available. If no healthy passive copy is available, the backup is taken from the active database copy. Whether the backup is taken from the active or the passive copy, the backup is managed as a single entity.
