◆ get_courses()

Get the courses to backup.

When there are multiple courses to backup enforce some order to the record set. The following is the preference order. First backup courses that do not have an entry in backup_courses first, as they are likely new and never been backed up. Do the oldest modified courses first. Then backup courses that have previously been backed up starting with the oldest next start time. Finally, all else being equal, defer to the sortorder of the courses.
