virtual copies either through Recovery Manager or via Windows’ automatic scheduled task
application. For more information, see
“Using the Recovery Manager GUI” (page 31) or
“Running Recovery Manager as a Scheduled Job” (page 77) .
•
With Recovery Manager’s optional policy settings, you can maintain a specified number of
the latest virtual copies to stay online. These online virtual copies can then be mounted to the
staging Exchange server for point-in-time recovery, thus eliminating the need to restore from
tape, which can take hours.
•
After the virtual copy has been mounted to the backup server, you can perform a backup to
tape of the virtual copy using Recovery Manager.
•
You can easily recover data using Recovery Manager's file copy and volume promote restore
features.
NOTE: Backup to tape can be performed in one easy command with a quick backup. For more
information, see “RMExch backup” (page 51) .
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 whether 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
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. Microsoft does not support restoring to the
passive copy. Note that you must reseed the passive copy 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.
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
mailbox database you want to recover and select Dismount Database.
NOTE: If in a cluster, go to the Cluster Administrator and take the Exchange Information
Store Instance resource offline. If not in a cluster, go to the services menu and stop the Exchange
Information Store Service.
5. Mount the desired virtual copy to the staging Exchange server either from the Recovery Manager
GUI or from the command line using the RMExch mount command. For more information,
see
“Using the Recovery Manager GUI” (page 31) or “Using the Recovery Manager CLI”
(page 49) .
