10 to 15 minutes to scan a full system and backup changed items
doesn't seem long to me. I am assuming you have it set to backup ALL,
not just your user folders. So we're not just talking about documents
you edit. But anything system files settings files anything that it
backs up it looks
I don't know, but I think that makes sense. Although you said that Super
Duper only makes note of the changes, there is no way that i know of for it
to automatically know what those changes are. Also, I would think the time
it takes to scan your drive depends on how much you have on it.
