Hello Mario,
You do not need to backup and restore. Instead, follow these simple steps:
- In the template course, place the questions in the quiz category or in the course category of the question bank, because it is where teachers generally have access.
- Create a new blank course: Site administration / Courses / Add a new course.
- Edit the new course: Actions menu (Gear in Boost theme) / Import / select the Template course.
The new course will then include a copy of the questions.
