Backing up Documents without Internet.

Is it possible to import or export a Pages file using this method? I know you can plug in USB keyboards and use them, which is cool, but I am curious about the ability to backup documents. I'm going into the Peace Corps and don't want to carry a clunky laptop that might get stolen. My iPad with its case looks like a standard notebook (with papers sticking out and everything) and having the ability to backup documents without the Internet would be awesome.
