Am posting this on behalf of a Moodle admin who is shy!
And cannot disclose info that might be helpful ... but ...
Server is Linux and hosted on TMD ... has WHM and cPanel.
If cron is run, a backup of a large course is run. Course has an assignment for students to upload video of themselves. It is an ongoing never ending course, so many users and many users have done the assignment.
The backup fills up their data partition (moodledata/temp/backup/) and we can watch the files directory of that backup fill up. They are apple .mov files. And I can verify at least the mimetypes via file -b command. Have to manually erase files to prevent filling up - thus backup never really builds the finished backup.mbz file.
Have truncated any tables in DB for scheduling autobackups ... have turned autobackups off in Admin UX + have a line in config.php that makes sure it's off, but ... the backup kicks in.
In viewing the actual course, that assignment isn't present ... not even hidden!!!
I cannot find where it's coming from!!! (GRRRRR!) There is no other cron job that points to code/admin/cli/backup.php
So stupid question ... is the scheduling of backups cached somewhere else? ahoc task?
Have never seen nor experienced similar!
