Here are the steps for performing the restore:
1. Create the Recovery Exchange Database in Exchange
2. Restore the Database from backup in CommVault
3. Restore the contents of the mailbox in the recovery database to a place holder mailbox in Exchange.
4. Create a PST of the of the mailbox content of the place holder mailbox in Exchange.
Create a Recovery Database in Exchange 2013:
The server MBX1 has a dedicated mount point for restoring databases in Exchange. The mountpoint is C:RecoveryDB on MBX1. Run the following powershell command:
New-MailboxDatabase -Recovery -Name RDB_DB01 -Server MBX1 -EdbFilePath “C:RecoveryDBRDBDB01.edb” -LogFolderPath “C:RecoveryDBRDB logs”
Restore to the Recovery Database in CommVault:
1. Ensure the database you want to restore is dismounted and marked for overwrite.
2. From the CommCell Console, navigate to Client Computers | <Exchange CommVault Client>. Right-click Exchange Database and then click All Tasks | Browse Backup Data.
3. Select your Browse option for when to Restore From. Select the date of the last known good backup of the data that needs to be restored.
4. In the left pane of the Client Browse window, navigate to Exchange Database | Microsoft Information Store | <Storage Group>. Select the database to be restored in the right pane and click Recover All Selected.
5. In the Restore Destination section, select the destination client that holds the Recovery Database; MBX1. In the Destination DB, select the new recovery database that was created; RDB_DB01. Click OK. You can monitor the restore in the Job Controller so you know when it is 100%.
Extract Content from Recovery Database:
1. Mount the Recovery Database so we can access the content by running the following in Exchange PowerShell:
2. The following PowerShell command we can use to extract content of the mailboxes. The content can be extracted and placed into another mailbox. We will use a place holder mailbox called r_steve2010 and put all of the content into a recovery folder which will be created during the mailbox restore.
Exchange 2013 command:
New-MailboxRestoreRequest -SourceDatabase “RDB_DB01” -SourceStoreMailbox “<DisplayName of User on RDB Database>” -TargetMailbox “r_steve2010” -TargetRootFolder Recovery -AllowLegacyDNMismatch
Exchange 2010 Command:
Restore-Mailbox -Identity “R_Steve2010” -RecoveryDatabase “RDB_DB01” -RecoveryMailbox ‘steve2010’ -TargetFolder Recovery
3. From here we can either provide access the dummy account, or export the content from the dummy mailbox to a PST and give it to the customer. To export it to a pst, run the following Powershell Command:
New-MailboxExportRequest R_steve2010 –FilePath “\servernamesharenamefilename.pst” -acceptlargedataloss -baditemlimit 999
Now we have successfully restored and recovered content from a Commvault backup.
