You can use Windows Server Backup to back up and restore your Exchange databases. During the backup operation, a consistency check o f the Exchange data files is run to make sure that the files are in a good state and can be used for recovery . If the consistency check succeeds, Exchange data is available for recovery from that backup. If the consistency check fails, the Exchange data isn't available for recovery.

  Backup issues and limitations with Exchange 2010 and DAG http://blogs.technet.com/b/ehlro/archive/2010/02/13/backup-issues-and-limitations-with-exchange-2010-and-dag.aspx   13 Feb 2010 12:14 AM   · I have come up with the following conclusions after testing some backup functionalities with Windows Server Backup and Exchange 2010 with DAG. There are some limitations that we'll have to be aware of: 1. Windows Server Backup (WSB) When using Windows Server Backup to backup an Exchange 2010 database the backup fails under the following conditions: - Each database and associated logs are stored on a dedicated LUN (these are presented by the SAN software to the OS as separate volumes as expected in Disk Management) - The database LUN is presented via a mount point - Some database copies on the server are not active For example, two mailbox servers that are DAG members (SERVER1 & SERVER2), and two mailbox databases (MBX1 & MBX2). If both mailboxes databas
