Under Windows 2012 you are trying VSS backup and you receive an error message “System Image Error: The system writer is not found in the backup”
This issue occurs for lack of appropriate permissions to files in the %windir%winsxsfilemaps or %windir%winsxstempPendingRenames directories.
At the time of writing this blog, this is an unpublished bug for Windows Server 2012.
Cause
Causes for this issue are:
- When Visual Studio 2012 is installed, more than 1,000 subdirectories in the following location: C:WindowsMicrosoft.Net
- Windows Server 2012 limits any directory from containing more than 1,000 subdirectories.
- When the system state writer tries to back up the folder, the issue that is described in “Symptoms” section occurs.

Resolution
To resolve this issue, type the following commands from an elevated command prompt:
Takeown /f %windir%winsxstempPendingRenames /a icacls %windir%winsxstempPendingRenames /grant "NT AUTHORITYSYSTEM:(RX)" icacls %windir%winsxstempPendingRenames /grant "NT Servicetrustedinstaller:(F)" icacls %windir%winsxstempPendingRenames /grant BUILTINUsers:(RX) Takeown /f %windir%winsxsfilemaps* /a icacls %windir%winsxsfilemaps*.* /grant "NT AUTHORITYSYSTEM:(RX)" icacls %windir%winsxsfilemaps*.* /grant "NT Servicetrustedinstaller:(F)" icacls %windir%winsxsfilemaps*.* /grant BUILTINUsers:(RX) net stop cryptsvc net start cryptsvc
Type the following command to verify that the system writer is now listed:
vssadmin list writers

Now try your VSS Backup



NOTE: After following the above steps if the issue is still not resolved then please install the server this Hotfix from http://support.microsoft.com/kb/2807849/en-us
Awesome article! I noticed the commands don’t have slashes, so I found them from another site. Just posting here to help.
Correct commands with slashes:
Takeown /f %windir%\winsxs\temp\PendingRenames /a
icacls %windir%\winsxs\temp\PendingRenames /grant “NT AUTHORITY\SYSTEM:(RX)”
icacls %windir%\winsxs\temp\PendingRenames /grant “NT Service\trustedinstaller:(F)”
icacls %windir%\winsxs\temp\PendingRenames /grant BUILTIN\Users:(RX)
Takeown /f %windir%\winsxs\filemaps\* /a
icacls %windir%\winsxs\filemaps\*.* /grant “NT AUTHORITY\SYSTEM:(RX)”
icacls %windir%\winsxs\filemaps\*.* /grant “NT Service\trustedinstaller:(F)”
icacls %windir%\winsxs\filemaps\*.* /grant BUILTIN\Users:(RX)
