I have an SBS 2011 that stopped backing u due to a VSS issue. This includes refusing to do Acronis backups.
I've seen this a few times and usually the fix is:
1.Open an Administrative command prompt.
2.Change directory to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN
3.Run PSConfig.exe -cmd upgrade -inplace b2b -force -cmd applicationcontent -install -cmd installfeatures
In this case however the manual update fails:
I have filtered out all Errors and Warnings from the update logs.

Does anyone know how I can fix this please?
Any suggestions would be appreciated.

We also experienced a failure the first time it was run, however we simply re-ran it again and it succeeded on the second attempt.
We did it a time when there were very few users logged on.
I hope it works for you. Try it a few times in succession, just to be sure!!!
