I am looking for a way which will allow me to back up and reset a course preserving the assignment grades given, but removing the assignments themselves.
Currently, we back up the course, download the back up and restore it on an archive moodle. It would be nice to be able to create the backup, then reset the course removing the assignments thus reducing the file size used on our servers. Some courses have a mixture of assignments, quizzes etc. The quizzes take up hardly any space, however some assignments might be rather large.
If this doesn't make sense, what other backup/ archiving solutions does everyone suggest?
