Windows Server Backup is included with Windows Server 2008 R2 and can be a great quick-and-dirty way to back up an Exchange server. Scott Lowe explains how to use this tool.


No matter how small the Exchange implementation, the data needs to be backed up. Many Exchange shops (particularly smaller ones) have relied on the ubiquitous Windows Server Backup utility to protect their Exchange environments against disaster. Although there was a period of time when Exchange and Windows Server Backup didn’t work together, with Windows Server 2008 R2 and Exchange 2010, this is not the case, and the backup and recovery of Exchange using this tool is a relatively simple process.

For the demonstration in this tutorial, I’ll back up a single Exchange 2010 mailbox database that exists on a server named MAIL3. At Westminster College, we’re currently in a pilot phase for an Exchange 2010 rollout, and we’re using Windows Server Backup during this phase. Once we’re in full production, we’ll move to our normal enterprise backup application.

This blog post is also available as a TechRepublic gallery.

How to use Windows Server Backup with Exchange 2010 Figure A gives you a look at the Exchange Management Console view of this database. The other two databases you see reside on a different Exchange server.

Figure A

We’ll back up the default mailbox database on MAIL3. Start the Windows Server Backup tool by going to Start | All Programs | Accessories | System Tools | Windows Server Backup. More than likely, you’ll end up with a screen like the one in Figure B that tells you the backup tool is not yet installed on your server.

Figure B

Windows Server Backup is not yet installed. To add the Windows Server Backup bits to your Windows Server 2008 R2 server, open Server Manager, navigate to the Features item, and click the Add Features link (Figure C).

Figure C

Click Add Features to add a new server feature. On the Select Features page, locate the Windows Server Backup Features option and select it (Figure D). Although it’s not required, it’s also recommended that you install the Command-Line Tools so that you can script backup jobs if you like.

Figure D

Choose to add the backup tool. When you get to the Confirm Installation Selections page (Figure E), look over your selections and click the Install button to add the features. At the end of the process, you will receive the results screen shown in Figure F.

Figure E

Review your selections and click Install. Figure F

The backup tool has been installed. Now that Windows Server Backup is installed, when you restart the utility, you’ll be greeted with a screen like the one in Figure G. At the top of the window, Windows Server Backup will tell you that there are no current backups configured, and all of the informational areas of the window will be blank since there is no detail to share until after an initial backup is run.

Figure G

The Windows Server Backup window is mostly blank to start. I’ll jump right into creating a backup schedule in order to schedule a regular backup of this Exchange Server database. To start the process, go to the Action menu and choose Backup Schedule (Figure H).

Figure H

Schedule a server backup Starting the backup schedule kicks off a wizard that begins with a welcome screen that outlines what decisions you need to make (Figure I). For the purposes of this article, I’ll stick mostly with defaults.

Figure I

Backup Schedule Wizard Getting Started page On the next page of the wizard, you’re asked to decide what you’d like to back up. You can choose to back up the entire server (this includes all data, applications, and system state), or you can choose to perform a custom backup, which allows you to make granular options about what to back up. You see in Figure J that I’m performing a full server backup that will use 17.52 GB of space.

Figure J

Choose what to back up Although the backup default is to run every day at 9:00 P.M., you can choose to run the backup at a different time (Figure K) or, if you need a shorter recovery period, can choose to run multiple backups each day. To add additional daily backups, select the button next to More Than Once A Day, specify the times you’d like, and click the Add button. After you make your choices, click the Next button.

Figure K

Decide at what time(s) each day you’d like to run backups. With the “what” and the “when” out of the way, it’s time to consider the “where” (Figure L); specifically, you need to make sure to back up your information to a location that can survive a server failure. You can choose to back data up to a hard drive that you’ve dedicated to this purpose. Ideally, this would be a removable drive of some kind that you can store away from the server. If you can’t do this, you can back data up to an existing server volume, although you may take a performance hit and, if the server is lost in a disaster, recovery won’t be possible. The option that I prefer is to back data up to a volume on a separate server. In my case, this second server resides in a different building.

Figure L

Where do you want to save backups? When you choose the remote location option, you’re told that each backup will overwrite previous backups and only the latest backup will be available (Figure M). If you need multiple backups to be available, consider other backup options.

Figure M

Heed the warning When you choose the remote backup option, you need to specify where the backup should be saved. On the screen shown in Figure N, you’ll note that backups are being written to a server named Backup and to a folder named MAIL3 on a share named Exchange10. In the Access Control section of the window, the Inherit option is selected, indicating that anyone who has access to the shared folder also has access to the backup file. As such, set carefully controlled share and NTFS permissions on the resource.

Figure N

Specify where the backup should be saved For a remote share, you need to provide a user name and a password that has access to the backup destination (Figure O).

Figure O

Provide credentials for the remote backup location Finally, the confirmation page appears, providing you with an opportunity to review your backup selections (Figure P). When you’re done, click the Finish button.

Figure P

Review your backup selections When you get back to the backup console, you can click the View Details link under Next Backup to see details about your pending backup. Figure Q shows this detail window for the backup we just created.

Figure Q

Details about the next scheduled backup If you’d like to kick off a manual backup before the next scheduled backup, go to Action | Backup Once. On the first page of the Backup Once Wizard (Figure R), you’re asked how you want to run the backup. Do you want to use the same options you used for your scheduled backup, or do you want to choose different backup options?

Figure R

Backup Once options The Backup Once Wizard provides you with a summary page. Click the Backup button to begin the backup process (Figure S). During the backup process, the window in Figure T will display on the screen so that you can watch backup progress. At the end of the process, you’ll see a final completion page (Figure U).

Figure S

Backup summary page Figure T

Backup status page Figure U

The backup is complete. Proof How do you actually know that Exchange was appropriately backed up? That’s revealed during the restore process. Although I’m not covering restores here, I will share the screen in Figure V; this shows that the Exchange application was backed up and that, specifically, the database on the server named MAIL3 was the one that was saved.

Figure V

The restore process reveals that the Exchange database exists in the backup. Summary While suitable mostly for small organizations and those running pilots, the Windows Server Backup utility can be a great way to back up your Exchange 2010 server without having to invest more dollars in software.

Restaurando un buzón de Exchange 2010 usando una Recovery Database y Symantec Backup Exec 2010 5 10 2010

Los grupos de restauración de almacenamiento que podíamos ver en las antiguas versiones de Exchange 2003/2007 han desaparecido con la aparición de la nueva versión de Exchange Server 2010. En este documento podremos ver cómo crear una base de datos de recovery así como realizar una restauración de un buzón de Exchange 2010 utilizando Symantec Backup Exec 2010 y un par de comandos desde la poderosa powershell de Exchange server 2010. Como comentare durante el documento, estas opciones de restauración son similares con cualquier software de backup compatible con Exchange Server 2010.

El primer paso que debemos realizar es crear una base de datos de recuperación (recovery database) para realizar esto vamos a la PowerShell de nuestro servidor Exchange 2010 y lanzamos el siguiente comando: New-MailboxDatabase -recovery -name (nombre de la base de datos restauración) -server (nuestro servidor de Exchange) -EdbFilePath (Ruta de los archivos de base de datos) –LogFolderPath (Ruta de los logs de la base de datos)

Este comando nos creara una base de datos de recuperación la cual podrá ser usada para realizar una restauración de una base de datos desde nuestra solución de Backup.

Por tanto el siguiente paso desde nuestra solución de Backup es realizar una restauración completa de la base de datos a restaurar. En este ejemplo hemos utilizado Symantec backup Exec 2010 R2 aunque estas opciones de restauración como hemos comentado son similares en cualquier solución de backup compatible con Exchange 2010.

Una vez dentro de las opciones de restauración de nuestra base de datos debemos decirle cual es el servidor de correo así como su recovery database, en este caso la base de datos de restauración la hemos llamado RECDB que hemos creado desde la powershell:

Una vez finalizada la tarea, nos habrá restaurado todo el backup en nuestra base de datos de restauración, por tanto el siguiente paso que tenemos que hacer es combinar la base de datos de producción con nuestra base de datos de restauración.

Una vez llegado a este punto tenemos numerosas opciones desde restaurar un solo buzón, una carpeta, correos .. en el mismo buzón, otro buzón de usuario u otro servidor Exchange.

Todas estas opciones se pueden ver en el siguiente enlace donde se explica el comando restore-mailbox en profundidad: Un ejemplo de uso es el siguiente:

Vamos a restaurar un buzón llamado “sistemas” de la base de datos de recuperación sobre el mismo buzón de la base de datos de producción. Para ello ejecutamos el siguiente comando:

Restore-mailbox –Identity (nombre del buzón) –Recoverydatabase (nombre de la base de datos de recuperación)

Como podréis ver en la imagen, nos preguntara si queremos restaurar nuestro buzón “sistemas” de la base de datos de recuperación sobre la de producción, le damos “Y” y ya hemos restaurado por completo nuestro buzón.

Como os he comentado esta es solo una de las numerosas opciones de restauración del comando restore-mailbox, no dejéis de revisar el siguiente enlace para probar otras opciones de restauración:
