The bad news is that unless you can work something out with archive.org (which seems unlikely; web-archive items are restricted to protect them legally), or use the old waybackup interface (which I don't think works anymore), or use the wayback machine (which last I heard only supported a few hundred connections per second) you'll only be able to back up half their data. Still, non-web items seem like a nice place to start. """]]
