Using the Hijack FTP services, you can simply copy the contents of the /drive0/fids and drive1/fids to a safe place, and that's your backup.

Anyone else agree or disagree with that? That should cover playlists and tunes completely, right? If you're forced to restore the player, you will need to do some synchs to rebuild the datbase, but that's about it.

If it's that simple, then I think I'll add that to the FAQ.

Of course, it's only useful for those with ethernet, but it's a start.
