Unitrends data protection for Exchange 2007 and 2003 enables you to backup multiple storage groups or an individual storage group.
Unitrends does not allow the selection for protection of individual databases within a storage group. The reason for this is the transaction logs for the entire storage group are backed up for each database selected. Thus a full backup must be run on every database in a storage group in order for the transaction logs to be properly handled for full/differential backups.
