I have been contacted by some people asking about backup issues they are experiencing on Windows Server 2012 . The issue is related with the Microsoft November update release KB3000853.

My recommendation is to remove the update until Microsoft fix the issue as it affected Microsoft and third party backup products.

As per Taylor Brown’s (Hyper-V Program Manager) blog,

“We are getting reports that some customers are seeing backup jobs fail after installing the latest Windows Updates including the November rollup (http://support.microsoft.com/kb/3000853).

We believe there is an issue with the KB3000853 update and are working to fix it as quickly as possible, in the interim downloading and applying http://support.microsoft.com/kb/2996928/ should address the problem”
