And we're off on a tangent ;-P

You want to look at rsync, or just write a shell script to do it. That's the joy of the Nxxx. It's just a Linux tablet computer under the hood. Do what you want.

NOTE: rsync can do a scheduled backup to a remote box. You can schedule a cron job to do it whatever way you want - ftp, rsync, tar, etc. I haven't got to the point where I do anything like that myself, but I'd probably use rsync until I get a better handle on what's available for the Nxxx Linux. I usually prefer to do this stuff with ncftp (nice batch features), but I haven't looked to see if it's available yet.
