This error indicates a problem communicating with Volume Shadow Copy Service (VSS) writers on your system. Look in your Windows Event log for VSS error messages that give more information and check that the VSS service is started.

1. Check the VSS service isn't disabled.
    
2. Changing the startup type of the VSSservice and rebooting can often resolve issues.
   1. Right click My Computer.
   2. Select Manage.
   3. Select Services tree node.
   4. Right click Volume Shadow Copy.
   5. Select Properties.
   6. Change startup type to Automatic
      
      
      
      
   7. Reboot
       
3. Sometimes, re-registering VSS core components can fix errors. 
   1. Copy the following commands to Notepad:
      cd /d %windir%\system32
      net stop vss
      net stop swprv
      regsvr32 /s ol32.dll
      regsvr32 /s oleaut32.dll
      regsvr32 /s vss_ps.dll
      vssvc /register

      regsvr32 /s msxml4.dll
      vssvc /register
      net start swprv
