In order for DPM2007 to backup the system state of a Windows Server 2008 machine you have got to install Windows Backup and all of it’s subfeatures. This can easily be done using the following command:
servermanagercmd -install backup -allsubfeatures
If you don’t do this you will get an error message similar to this one:
(ID 30214 Details: Internal error code: 0x809909FB)
you are missing an R “seRvermanagercmd -install backup -allsubfeatures”
=)
But TKS it was very helpfull!!!
