Hi everyone, Andy Nadarewistsch here. While the restore process for System Center Data Protection Manager 2007 (DPM 2007) and System Center Data Protection Manager 2010 (DPM 2010) is the same for all versions of Exchange, the procedure on the Exchange side has gone through some changes. Detailed instructions for dealing with Exchange 2010 recovery databases can be found here.
One of the most common restore methods used in DPM is to a recovery database. Let’s do a basic step-by-step process here.
Some general information:
Changing the status of a database from active to passive or vice versa may affect the recovery process. If the database is passive, DPM cannot perform a Volume Shadow Copy Service (VSS) recovery. For further information please refer to Restoring a Database Availability Group Copy
Recovering to the active database is the same as recovering to an Exchange Server 2010 standalone node. The Exchange Server administrator must synchronize the passive copy from the recovered active copy by running the Resume-MailboxDatabaseCopy cmdlet on the Exchange server. You can recover a database only on the node that was protected.
DPM supports the following five types of recovery for Exchange Server 2010 mailbox databases:
As stated, this topic will look at this process in the form of restoring to an Exchange RDB and then restoring a user mailbox. The Exchange page above lists specifics of doing other broader types of recoveries.
The biggest thing that DPM administrators should be concerned with is that there is a recovery database (RDB) created on one of the Exchange servers.
Step 1: Creating an Exchange RDB for restore
The process to do this is through Exchange PowerShell Management.
NOTE You can't use the Exchange Management Console to restore data using an RDB. The only way to do this with Exchange 2010 is using the Exchange Management Shell.
1. On one of the Exchange 2010 servers, open the Exchange Management Shell.
2. Once connected, run the following command:
New-MailboxDatabase -Recovery -Name %RDBName% -Server %ExchangeServerName%
RDBName will be the name of the recovery database and ExchangeServerName will be the name of the exchange server where the RCB will be created
You can also set the location for your RDB using the following commands
New-MailboxDatabase -Recovery -Name %RDBName% -Server %ExchangeServerName% -EdbFilePath %targetDBPath% -logFolderPath %targetlogPath%
IMPORTANT Make sure to create the RDB on an Exchange server that has the protection agent installed from the DPM server where you will be doing the restore from as you can only recover to servers with the agent installed.
To be sure the mailbox database was created, you can run the following command to list all of the mailbox databases in the Exchange organization (or you can pare that down using the –Server %ServerName% to list only mailbox databases on a specific server)
Let’s stop for a second and take a look at what is seen on the Exchange server side.
Open the Exchange Management console >Organization Configuration >Mailbox. If it’s already open click refresh. The first thing is by default the RDB is dismounted and is set to allow to be overwritten.
Right-click on RDB, select Properties. The general should show “dismounted” and maintenance tab will have the “This database can be overwritten by a restore” checked.
There are some restrictions of an RDB due to its purpose. If these are not adhered to, it could cause problems restoring from DPM. Some examples are:
For a complete list reference see Recovery Databases
Step 2: Doing Restore through the DPM console
1. Once the creation of the recovery mailbox database has been confirmed, open the DPM console and navigate to the Recovery tab.
2. Find the mailbox database with the user’s mailbox you wish to recover and then find the user and the point in time you wish to recover. With the user highlighted, in the Actions menu on the right, click Recover.
3. You will be presented with a Recovery Wizard which will have you confirm the information that you have chosen to restore. Confirm the user mailbox and time/date stamp for the recovered items and click Next.
4. On the Select recovery type page, there are three of recoveries that can be chosen:
a. Recover mailbox to an Exchange server database: Use this option when restoring to an Exchange server where a recovery database mailbox has been set up. This will allow Exchange administrators to recover information from it. b. Copy to a network folder: This will make the database and its log files available to an Exchange administrator for advanced recovery options if so requested. c. Copy to tape: This copies the files to a tape to allow you to move the files to an alternate location for recovery. This will be disabled if there is no tape drive/libraries or there are not enough tape drives.
a. Recover mailbox to an Exchange server database:
Use this option when restoring to an Exchange server where a recovery database mailbox has been set up. This will allow Exchange administrators to recover information from it.
b. Copy to a network folder:
This will make the database and its log files available to an Exchange administrator for advanced recovery options if so requested.
c. Copy to tape:
This copies the files to a tape to allow you to move the files to an alternate location for recovery. This will be disabled if there is no tape drive/libraries or there are not enough tape drives.
For our example, we will choose the first option and click Next.
5. The Specify Destination screen will now prompt you for the Exchange server and database name. The server will need to be one that has the DPM agent installed from this DPM server. The Exchange server and database name will be the ones specified in Step 2 above. Once confirmed, click Next.
6. For the Specify Recovery Options page, you can select to mount the database after it’s recovered among other settings. Verify you have the selections you want and click Next.
7. For the Summary page, review the selections you have made to make sure everything is correct.
8. Once the restore has completed on the DPM server, the Exchange administrators can now do the restore of the mailbox from the Exchange Management Shell.
9. To restore, use the following command:
Restore-Mailbox –Identity %Username% -RecoveryDatabase %RDBName%
Username will be the email username of the user mailbox being recovered and RDBName will be the name of the recovery database (from Step 2 above)
If we had looked at the Exchange RDB before we did the restore the follow items would be noticed. The RDB would have been mounted and the “This database can be overwritten by a restore” box unchecked.
Remember: Only one RDB can be mounted at a time and the overwrite flag must be set to do a restore. If I tried to do a recovery to the same RDB I would have received the following error:
If I tried to recover to another RDB2 while RDB1 was mounted I would have gotten the following error:
After the failure, the Exchange RDB2 will go into a dismounted state.
To get back to square one just right-click > dismount for all RDBs and ensure the flag for “This database can be overwritten by a restore” is checked.
NOTE You can also dismount an RDB via Exchange PowerShell:

Thanks for the detailed explanation!! Recently, we encountered server failure problem in Exchange 2010 server due to power outage issue. After running eseutil tools , we had lost approx 40% data due to the severe corruption in Exchange databases. Then,
we decided to go for a third party application and picked this one: http://www.recover-computerdata.com/exchange-server-recovery.html It helped us to easily recover and restore the complete Exchange 2010 server data.
Thanks for sharing the useful information !. Corruption in Exchange databases is really very serious concern and sometimes leads to data loss situations. In order to fix the corrupted items in MS Exchange server. In case of severe corruption or when inbuilt tools do not work, then it is good to use a third party tool. One such popular application that helped us in repairing and rebuilding the corrupted databases in our Exchange 2010 Server, is here: http://www.serversdatarecovery.com/exchange.htmlOne of the best aspects of this software that we liked is that we mounted the repaired database directly to production server without any issue. A free trial version is also available on its official website !Good Luck !Jimmy
Well described, I found good information related to restore exchange mailbox database by using SCDPM but I found a helpful resource from
http://www.lepide.com/exchange-manager/ for restoring mailbox database. This tool allows to export or import mailboxes/pst/ost files. In order to fix the exchange server corruption issues and migrate single
or multiple mailboxes from offline edb, live exchange public folder or a live exchange server to another live exchange server, public folder, office 365 mailboxes and hosted exchange server.
For an easy and quick conversion of edb to pst format, I can suggest you to go in for a utility tool which does such operations quickly.
The software has been designed with many advance features like repairing, rebuilding and converting EDB to PST files. The company also offers demo version at free of cost to check its efficiency.
Recovering Exchange using System Center Data Protection no doubt provides Admin more power with enhanced virtualization capabilities and cloud backup support. But this solution may not be applicable in all situations such as when backup is not taken using
DPM . In those situations for secure and quick solutions to Restore inaccessible/Deleted Exchange 2010 Mailboxes you may have great help from this thread:
