Hi
Do you mean Site administration > Courses > Backups > Automated backup setup? Then No, it makes a backup per course, as you can see in their names like sicherung-moodle2-course-993-abu_4j18-22a-20200908-0150.mbz, where '993' is the course ID.
But the script does not backup every course, only those which satisfy the criteria in the setup mentioned above.
