Windows 10 – Window System Image Backup fails error code (0x807800C5) (0x80070020)

There was a failure in preparing the backup image of one of the volumes in the backup set.
The process cannot access the file because it is being used by another process.

All I can tell you folks is what worked for me.

  1. Try and shutdown the computer (not a restart).
  2. Turn on your computer and try again.
  3. If that don’t work, run these command in an elevated (administrator) command prompt.
    1. DISM.exe /Online /Cleanup-image /Scanhealth
    2. DISM.exe /Online /Cleanup-image /Restorehealth
    3. Shutdown the computer (not a restart).
    4. Turn on your computer and try again.
  4. If that doesn’t work, in an elevated (administrator) command prompt, run:
    1. sfc /scannow
    2. If that checks out okay, in the same windows, run a chkdsk:
      1. chkdsk [Drive:] [parameters]  “Example:” chkdsk c: /f /r /x
      2. Enter Y in order to have this process run the next time the system restarts.
      3. Restart your system.
  5. If this doesn’t work, browse the web and find another solution.
