You should know when to use SnapManager to recover an Exchange 2010 mailbox from database failure or data corruption.
The database switchover to a different server in the Database Availability Group (DAG) can be done using the EMC or the Exchange management shell.
Use SnapManager in the following situations:
- When using Exchange Server 2010 and DAG cannot recover the failed database.
- When using Exchange Server 2010 and DAG to recover database will cause data loss.
- When using Exchange Server 2010 and DAG cannot recover the database to a particular point in time: for example, when a virus has spread to all copies of databases.
- When using Exchange Server 2010 and DAG is confusing to the administrator, and using SnapManager Restore is simple, fast and reliable.
