[time-nuts] Odetics 325 & 425: File recovery

The problem nowadays is not the storage, it's the backup software.
I have most of my important data in 4 places: two web sites, main 250 GB
hard drive and external 500GB Western Digital USB Hard Drive (highly
recommended). What I call "important data" is about 30 GB worth of stuff
that is typically copied in all 4 places. The problem is keeping everything
in sync. Syncing between two local resources (main hard drive and USB hard
drive) is not too hard, considering the transfer speed that can be achieved,
but mirroring the web resources is a pain, partly because of speed and
partly because of OS differences in file name rules (Windows/Linux). I have
not found the software I wanted (only looked at free/cheap stuff) so I am
considering writing my own (Visual Basic).
If anyone has suggestions for free/cheap commercial or FOS software to sync
via ftp (Windows <-> Linux), I'll be glad to hear.
