Hi, we've hit a problem where we've lost our student data (specifically their assignment submissions). Our moodle accounts are synced with an external database. What we believe has happened is that over the summer holidays, our students' active status was removed, moodle picked this up, deleted them from the system, and when their active status was restored a week later, their moodle accounts were re-created but without their assignment histories, etc.
So potentially this is a big problem for us. To work out our options, we need a better grasp on what exactly happens when a moodle user account is deleted. Specifically, is their any chance that data will be retained in the database , and that we can recover it, or are the relevant database entries immediately cleared on user deletion?
Summaries of the deletion mechanism, pointers to documentation and/or suggestions for solutions would all be gratefully received!
(Course restoration won't work for us - it's not working on our installation and even if it was it's not set up to retain the course backups long enough to allow us to recover these users and their data. )
