DPM cannot create a backup because Windows Server Backup (WSB) on the protected computer encountered an error (WSB Event ID: 517, WSB Error Code: 0x79E280). (ID 30229 Details: Internal error code: 0x80990ED0)
When i checked details and event logs on Windows Server Backup of targeted protected computer, it was showing a error " The Operation was stopped detailed error: The system writer is not found in the backup"
I tried the following steps also to regain the permission on C:\WINDOWS\WINSXS\FILEMAPS directory with the following commands,
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)
- Stopped and started Cryptographic service
net stop cryptsvc
net start cryptsvc
Verified “System Writer” is listed or not using "vssadmin list writers" but it still invisible for me EVEN i tried the following link also

but nothing was helpful for me to get system writer visible.
