The AC auto backup will include the imported items, unless you click a box telling the program to exclude them. I don't remember if that's something new with v4 or not.

I wish the AC auto backup had a way of just saving the new info. Then there wouldn't be such a problem of uploading such large files every time. That would be a GREAT improvement in the backup program. I have to be honest, as much as I love AC, if I'd known that backing up my imported items would be such a problem, I would have just gone with something like MozyPro.
