We are using a test dev server for teachers to construct their online courses. We intend to back them up and move to a prod server using same version of Moodle, etc. In testing the restore function to a NEW course, when you restore a course the gradebook's categories and formulas are missing in the new course though teachers had set them up in the course. I listed this as a major bug because teachers would have to reset up their gradebooks for every course shell.

Steps to reproduce:

1. create a course backup without student data.
2. restore this backup to new course
3. check new course gradebook for categories and formulas that were in old course. they are missing.

Note, the grade book categories ONLY restore if you restore the course to a new course WITH user data.
