Back up the system partition
ADMINISTRATOR
We recommend backing up the system partition after any configuration changes.
Important
If you don't back up the system partition regularly, recovering a database will be more difficult. It's very important to keep a current backup the system partition—or at least back up every change to the system configuration.
You can use the Windows Server 2008 http://technet.microsoft.com/en-us/library/404a51b5-99a6-43d1-b5a5-36261cb5ade2 or other tools such as Veritas System Recovery to restore the system partition.
