Is that correct?
Thanks for the explanation - that makes more sense now.

Yeh spot on, sorry if I was being overly simple sounding that last time
Well in a way it is doing the same thing as your hard drive backup, it just cleverly knows there is already a copy of that video file on the HD so doesn't create ANOTHER copy of the same data, otherwise your backup would be 40gb and a lot of that be duplicates of existing material already on your HD.
This is why I don't get when people say backups take a long time... It's only actually writing in your case 114mb of data!
Mine takes less than 1 minute to do a full backup.
