9. Remount the database(s) to continue.
The Exchange server performs a soft recovery and automatically replays the log. After the
store is mounted, Recovery Manager confirms the restore.
Point-of-Failure Recovery for Volume Restore
To perform a point-of-failure recovery for volume restore:
1.
Move the currently existing log files on your mailbox database volumes that you want to roll
forward.
NOTE: If Windows does not allow you to move, or even copy, Exchange .LOG files because
the files are being used by another program, part of Exchange is still live. If this is the case,
move on to
the next step .
2. Perform a point-in-time recovery for volume restore: step 1 to step 4 .
3. With the Exchange database(s) dismounted, preserve the current log files on your mailbox
database volumes if you were not able to do so for
step 1 .
4. After you have taken all the disk(s) out of maintenance mode, perform the following:
a.
Copy the .LOG files that you preserved and overwrite the logs recovered, including the
extra logs not covered by the virtual copy. This process makes the recovery more
forward-in-time.
b. Delete the checkpoint file (.CHK).
c. Remount the database(s) to continue.
The Exchange server performs a soft recovery and automatically replays the log. After
the store is mounted, Recovery Manager confirms the restore.
Data Restoration Using a Recovery Database
A recovery database is a mailbox database that allows Recovery Manager to mounting a restored
mailbox database and extract data from the restored database as part of the recovery operation.
Recovery databases allow you to recover data from a backup or a copy of a database without
disrupting access to current data. Use the Restore-Mailbox cmdlet to extract mailbox content from
a restored database.
The following are required to restore data using a recovery database:
•
A recovery database must be created.
•
Recovery databases can only be used for Exchange 2010 mailbox databases.
•
The target mailbox used for data merges and extraction must be in the same Active Directory
forest as the database mounted in the recovery database.
•
The database and .LOG files containing the recovered data must be restored or copied into
the recovery database folder structure that was created when the recovery database was
created.
•
The database must be in a clean shutdown state. Use the Eseutil.exe tool to put the
database into a clean shutdown state.
Creating a Recovery Database
To create a recovery database:
1.
Start the Exchange Management Shell by clicking Start
→Program Files→Exchange→Exchange
Management Shell.
2. In the Exchange Management Shell window, enter the following:
New-MailboxDatabase -Recovery -Name <rec_database> -Server <servername>
