Application Event log on the SBS 2011 server shows Event ID 8230 (spfarm, spsearch) :

If Sharepoint Service Pack 1 is installed on SBS 2011, this extra step is needed for backups to be successful. The user must run the “psconfig” command to fix Sharepoint and backups

More information can be found here:



  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”
  4. If backups are still unsuccessful after doing the above, please reboot the VM and try again
