Microsoft VSS may malfunction on Windows SBS 2011 after Microsoft update installation.
Thread needs solution
Dear Acronis Customers,
Please be informed that recently an issue has been discovered and reproduced with Microsoft VSS under Windows SBS 2011.
The problem is: when a Microsoft Update is applied to Windows SBS 2011, Microsoft VSS stops functioning. This problem, in its turn, affects Acronis backups with Microsoft VSS used. To fix the issue, "PSConfig" command should be run on an affected machine.
You can find more details on this fix in the following articles:

Thank you.
