Your ability to perform an online backup is critical to the smooth operation of Exchange. An online backup requests the database page by page and verifies the checksum of each page as it requests it. This enables you to back up the database while it's in use, and it ensures the integrity of the database's pages. If your backup software isn't capable of backing up the Exchange Information Store online, you must dismount the stores in order to get a backup.
Several vendors sell backup solutions that include an Exchange agent:
