Emma,
I never did actually change the location of my backups under automated backup settings. I left them at their defaults when I first installed moodle, and have never changed them. Any idea why moodle would fail to find and delete the old backups. I have deleted all but one backup of each course through the "restore" page on moodle, but it appears the old backups are still taking up space on the server.
My first course has a backup size of about 250 MB, my second course has a backup size of about 100 MB. A few months ago, I was only using a few GB of my server space. It has steadily grown so that it is now 32 MB, and with my server full, no more backups can be made.
