Get ready, this can take a while Create a complete range of different Calender events including atleast *site events (sitepages->calendar->new event->type>site) *site events that are repeated (use the repeat setting while creating a calendar event) *user events (sitepages->calendar->new event->type->user) *group events *course events (gotto a course-> add calendar block-> click on month name->new event) *Course events with images in description *course events that are repeated (use the repeat setting while creating a calendar event) *activity events. (Activity events are automatically created when you create a activity with due dates) Backup the course, with default option. Make sure you see the check box "include calender events" during the backup and restore procedures. Just to be extra safe make sure course and activity folder in the backups have calendar.xml with respective events data Restore the course as the following on an existing course on same site on a new course on same site on an existing course on a different site on a new course on a different site Make sure in each case all events except site events and user events are transfered properly. (We are not backing up site events and user events) Make sure repeated events are properly restored. Make sure events with images are restored properly and images are present in the restored events. Also cross check the database to make sure the newly created events are associated with correct ids of activity, user and group.i.e they are tied to the new ids not the old ones run this test on atleast more than one type of DB
