Creating and Managing Courses
1. Course Copy
Though Course Copy was introduced to simplify the course import process, we do not recommend using it in its current form, or recommending it to your users. It has several flaws that can prevent it from working properly. For example: Course Copy will not work in courses that have at least one quiz (which may include a large number of your courses). You can follow this issue in the Moodle Tracker: MDL-69941.
It is unfortunately not possible to hide this feature from instructors by updating their role because the roles we'd need to disable would also prevent them from using the Import and Backup/Restore features.
