How to restore Exchange 2010 Database to Recovery Database (RDB)

November 25, 2011

The following guide summaries the mail steps How to restore Exchange 2010 Database to Recovery Database (RDB).


Step 1 – Create a new Recovery Database (RDB):

New-MailboxDatabase -Recovery -Name RDB-For-Mailbox1-Database -Server ExchangeServerName -EdbFilePath "D:\DataRecovery\RDB-For-Mailbox1-Database.edb" -LogFolderPath "D:\DataRecovery"”

Step 2: Restore the EDB/Logs files by using your backup software.

Step 3: Mounting the recovered  EDB/Logs

a. Copy the EDB/Logs to the "D:\DataRecovery\” folder.

b. Rename the old EDB file to “RDB-For-Mailbox1-Database.edb”.

c. Mount the database with the command “Mount-Database "RDB-For-Mailbox1-Database"”.

and review the database status by using the command:

Get-MailboxDatabase "RDB-For-Mailbox1-Database"” | fl

* Some third party providers allow you to recovery the data directly to the Recovery Database (RDB).

Step 3: Review the Recovery Database (RDB) content:

Get-MailboxStatistics -Database"RDB-For-Mailbox1-Database”

Step 4: Recovered the date:

Overwrite the user mailbox:

Restore-Mailbox -Identity ‘Yuval Sinay’ –RecoveryDatabase “RDB-For-Mailbox1-Database

* Please note that the step above may delete user data. Due this, I would recommended to use the next option.

Copy the data to recovery mailbox:

Restore-Mailbox –Identity  ‘Yuval Sinay’ –RecoveryDatabase “RDB-For-Mailbox1-Database”  -RecoveryMailbox “RecoveryMailboxName

Then you can you extract the data by using “New-MailboxExportRequest“ command, Outlook etc.
Step 5: Remove the Recovery Database (RDB) from the Exchange server:

Remove-MailboxDatabase –Identity “RDB-For-Mailbox1-Database”"



If the recovered database wouldn’t mount, please use the following commands:

“eseutil /mh” – to verify that the database is a clean state.
