Our Dept head is requesting quiz results from last semester. I restored class from backup to pull up results. There were none. Log file has losts of entries about Restoring quiz without user attempts. Restoring of user attempts will be implemented in Moodle 1.5.1 during Quiz restore. Later on I get: Creating log entries . . . action (quiz-preview) unknow. Not restored . . . . action (quiz-continue attemp) unknow. Not restored action (quiz-close attempt) unknow. Not restored . . . action (quiz-close attempt) unknow. Not restored I have been giving instructors backup files of their courses for archival purposes. I had expected that these files would serve as usable records of academic achievement.
