title: Windows Volume shadow copy error: 2155348129
body: <p>Developing a VSS writer app:<br>
  see this error during backup, initiated by windows backup tool,
  is there defined error codes for <code>2155348129</code> from Microsoft?</p>
  
  <blockquote>
    <p>The backup operation that started at '‎2010‎-‎07‎-‎20T02:54:19.354000000Z' has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '2155348129'</p>
  </blockquote>
  
  <p>This does not happen when <code>VSSwriter</code> service (my application) is stopped.</p>
  
  <p>Any help is appreciated. Nothing useful found on TechNet.</p>
  
  <p><strong>Hackish workaround</strong>:
  Interestingly the back up works is when "windows partition is made active". Of course this leaves the system non-boot-able upon restart</p>
