DPM – What is Initial Store ?

When you use the DPM to backup a Hyper-V Server, there’s a check box for Initial Store. What is that … you may wonder.

The initial store contains the security permissions for Hyper-V’s Authorization Manager (AzMan).  This is an xml file located in %systemdrive%\ProgramData\Microsoft\Windows\Hyper-V\. You only need to perform a restore if this xml file becomes corrupted or is deleted. 

Backing up virtual machines and the initial store are independent. You only need to back up the initial store if you are using the Authorization Manager in Hyper-V and don’t want to lose your settings.
