Dynamic Disk Hotfix

Quote from http://blogs.technet.com

A potential problem with Volume Manager on Windows Server 2008 systems may lead to data loss.

This hot fix is not DPM-specific.  However, because DPM servers do utilize dynamic disks, it is important to apply this hotfix on WS08-based DPM servers so that your backup-data is not lost from the DPM storage pool.

For more information please read the link below to the hot fix.

962975    Dynamic disks are marked as "Invalid" on a computer that is running Windows Server 2008 or Windows Vista when you bring the disks online, take the disks offline, or restart the computer if Data Protection Manager is installed

This hot fix does not apply to Windows Server 2008 R2

Back-up Exchange 2010

The current version of DPM is not Exchange 2010 aware*. Therefore you can not directly backup Exchange 2010 mailboxes with DPM2007.
For now (as a work around) there is a plug-in available for the Windows 2008 server backup feature that allows you to backup the Exchange 2010 databases. This plug-in is called WSBExchange.exe and is standard installed with Exchange 2010. The plug-in runs as a service (Microsoft Exchange Server Extension for Windows Server Backup), which can be used by Windows server Backup.

This is a basic way to project

• Backups are VSS-based only. You cannot make streaming ESE backups
• Backups are taken on volume level, To backup the database and log files you need to protect the full volume that contains these files.
• Only full backups can be taken
• Log file truncation will occur after a successful full backup.

First you configured Windows 2008 Server Backup locally on the mailbox server.
Then you can configure DPM to protect the backup files of Windows Server Backup on the mailbox server.

This is maybe not the most efficient way to protect your Exchange, but at least  it’s a work around till DPM is Exchange 2010 aware.

*For Exchange 2010 TAP customers there is a special version of DPM2007 available that is Exchange 2010 aware. But this version does not support any other data then Exchange 2010
