Good Morning Visvanath!
That's my point! I do know the difference between copy and backup, however, in Moodle it appears they can be used interchangeably. Of course, if I wanted to resurrect an old course that was backed up, I would use Restore.
One of the other responders to this post indicated that she uses backup/restore to copy a live course. Why would I want to go through backup/restore for a live course when I could use copy? Is there something that I am missing with the resultant course? For instance, if you don't want user data included, use XXX. If you do want user data, use XXX. Would it make a difference if it were a live course and you wanted to update it and have current and new users see the update?
It sounds like they do the same thing. You have options for both copy and backup that are similar. So, what I am looking for is a recommendation for 'Best Practice' on duplicating/versioning a course. What I think you are suggesting is that one should use 'Copy' for a live course and Backup/Restore for an old course?? Is the key eliminate here whether or not both courses would remain live?
Thank you for all your input. You are so knowledgeable and I thank you for sharing your knowledge with me, Visvanath.
