We do backups across our WAN for a number of school districts. It has
worked very well using Bacula. I have one odd ball school that is still
using OS 9, OS X would not be a problem. I had to set up a local Fedora
box at the school running Netatalk, so the two boxes can communicate.
This works fine, and the Apple server sees the Linux box as another
Apple, but I need a way to automate copying files from the OS 9 box to
the Linux box, which Bacula will backup each night.

I have zero experience with apple script, so not sure what to do here.
