I am wondering if a backup problem might be related to QuizPort. Let me explain.
On a site with multiple copies of my Newsroom 101 course in Moodle 1.9+, run by multiple teachers, the courses with the most students (around 50) and most completed activities (thus with the largest backups) are starting to fail during the normal Moodle backup procedure.
The two problem courses will go through all the backup steps, start to zip, then hang. If I set system paths to the server's /usr/bin/gzip, they go one more step, but stop with "An error occurred while copying the zip file to the course directory." In the temp directory, the temp backup file looks to be incomplete.
I'm referring to the backup that is set from the Moodle Site Admin block and can be scheduled to take place daily. (I am able to back up the whole site through the server and also by downloading the database and moodledata, but this is less useful in restoring one course.)
I've tried various remedies found on forums (such as modifying php.ini to increase memory_limit), but nothing has helped the largest two courses. I fear that other courses will stop backing up as students complete more work in them and their backups grow larger.
Gordon, is it possible that some limit inside the QuizPort Backup script could be contributing to this backup problem?
Or have you seen a way to solve this problem?
