What data is not containes in course backups?

By selecting all the options when setting up the backup you can include almost all the data in the course. However you should be aware of the fact that some things are not backed up:

• Quiz questions are only backed up if at least one question from their category has been added to a quiz.
• Scales are only backed up if they are used by at least one activity.
• Users' passwords are not backed up when the "Include enrolled users" option is selected.
