How to Restore a Microsoft Exchange 2010 Server by Overwriting an Existing Database

  • Last updated on

This article refers to Barracuda Backup Legacy Release firmware or newer, and Microsoft Exchange Server 2010.

This article assumes the Microsoft Exchange Server is installed and configured. This article describes how to restore an Exchange 2010 Server by overwriting an existing database or to an original location. You can also restore to a Recovery Storage Group (RSG).

This option overwrites all existing data. If you do not want to overwrite the database, see Restore to a Recovery Storage Group.

Take caution when overwriting an existing database; Barracuda Networks highly recommends restoring to a separate recovery database except in cases of extreme data loss or when performing disaster recovery.

If you do not want to restore your Exchange Server by overwriting the existing database, you can select a different option:

  • Restore Exchange 2010 to Recovery Database 

  • Restore Single Exchange 2010 Mailbox
  • Restore All Exchange 2010 Mailboxes

See Restore to a Recovery Storage Group for more information on these options.

Step 1. Allow Database Restore

  1. Log in to your Exchange Server as the administrator, and open the Exchange Management Console (EMC) from Start > All Programs > Microsoft Exchange Server > Exchange Management Console.
  2. In the left pane, expand Microsoft Exchange > Microsoft Exchange On-Premises > Organization Configuration, and click Mailbox:
  3. In the center pane, right-click the mailbox database you want to overwrite with the restore, and click Properties.
  4. In the Mailbox Database dialog box, click the Maintenance tab, and select This database can be overwritten by a restore:
  5. Click Apply, and then click OK to close the dialog box.
  6. Right-click the database, and click Unmount.

Step 2. Specify Barracuda Backup Restore Settings

  1. Log in to Barracuda Backup web interface, and select the associated Barracuda Backup Server in the left pane.
  2. Go to Restore > Restore Browser. Locate the Exchange 2010 Server, and click Restore.
  3. In the Restore dialog box, choose the Restore to location:
    • Original Location
    • Select an IP Address from the available servers
    • Enter an IP Address or FQDN
  4. Choose the Restore method as Restore normally, and click Start Restore.
  5. Go to the Reports > Restore page to monitor the restore progress.

Step 3. Mount the Database

Once the restore is complete, use the following steps to mount the database.

  1. Log in to the target Exchange 2010 Server as the Administrator, and open the EMC.
  2. In the left pane, expand Microsoft Exchange > Microsoft Exchange On-Premises > Organization Configuration, and click Mailbox.
  3. In the center pane, click the Mailbox Database that was restored, and in the right pane, click Mount Database.
  4. The database should now be ready to use; ensure users can access their mailboxes.
