      Description

      When restoring a backup (Moodle 2 mbz) containing 120 quizzes it takes a long time to complete the restore. To restore the previous course it took 10 minutes on a 4 processor, 16 GB RAM MySQL Database Server.

      When the subject was backed up and restored in a Moodle 1.9 environment the restore takes 2 minutes.

      We can provide 10 backup samples but not on this public tracker. This is due the presence of copyrighted documents in the backup.
