I tried to back up my course/site for the first time and recieved this error.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request"
I had a look on the server and cannot see a back up folder etc.
Do I need to create on? What is the backup.php?
I would have thought this should have been created automatically on install.
Moodle version 2.0.2
