Backing up clustered Hyper-v Hosts with DPM

I finally got Microsoft’s Data Protection Manager up and running so i can start backing up all the Hyper-V hosts on my cluster and ran into a little error. Hopefully this article will be out of date shortly… that’s assuming Micro$oft patches this issue….

Anyway Heres the problem i ran across. I had already installed agents on all the hosts of my cluster. went into DPM, selected the cluster and all the VMs i needed to back up were listed, but when i tried to select them to backup i got this:

One or more prerequisites for protecting this data source is missing.

Ensure that the following prerequisite software is installed on all the nodes in the cluster:

Windows Server 2008 with

Knowledge Base article 948465 (http://support.microsoft.com/kb/948465)

AND

Knowledge Base article 971394 (http://support.microsoft.com/kb/971394)

- OR -

Windows Server 2008 R2 with

Knowledge Base article 975921(http://support.microsoft.com/kb/975921)

AND

Knowledge Base article 975354(http://support.microsoft.com/kb/975354)

If you have already installed the required prerequisite, refresh the agent status in the management tab and try again.

Since i was using R2 I used the bottom 2 links, Requested the Hotfixes, and installed them. Its a relativity simple process, but some kinks are: you MUST install these hotfixes on ALL cluster hosts or shit gets fucking crazy! you may also get the error that some or all of the hotfixes are already installed, If so that means that they came down in a regular update (Its a good thing) in which case all you need to do is refresh the agents in the Management tab of DPM then recreate your protection group.

May seem like a useless post as the solution if referenced in the error report. But their KB leaves that last part out. Hope this helps someone!
