8.4 Recovery Procedures
In many cases, the Exchange server is able to quietly recover when a server crashes and the
contents of the database buffer in the memory are lost. Exchange automatically recovers when
you start the information store after the failure using the checkpoint file to identify the oldest
transaction not flushed to disk and then replaying log files forward. If the checkpoint file is
missing, all the log files are scanned to determine if any committed transactions have not been
written to the database. At the end, the database is consistent and can start normally. Most of
the time, recovering an Email or a user's Email is all that is needed.
Recovery Manager provides several options for a full mailbox database recovery:
■ point-in-time recovery
■ volume promote point-in-time recovery
■ point-of-failure recovery
■ single mailbox recovery
8.4.1 Point-In-Time Recovery
Recovery procedures for Exchange 2010 Database Availability Group (DAG) configurations
should be run on the active copy of the Mailbox Database. Restores to the passive copy is
not supported by Microsoft. The passive copy will need to be reseeded after a restore is
performed on the active copy.
To perform a point-in-time recovery for Exchange 2010:
1 In the Exchange Management Console, right-click the desired database you want to
recover and select Properties.
Result: The Properties dialog box appears.
2 Under the General tab, select This database can be overwritten by a restore.
3 Click OK.
4 On the Database Management tab in the Exchange Management Console, right-click
the storage group you want to recover and select Dismount Database.
