EEEEEEK! The hair on my neck is standing up straight! Have you heard of SAMBA? 
The linux mail server firewall etc machine has an extra 4TB disk on it as a 
backup for the other systems, although a piddly 4TB is small when I save the 
entire 3G RAID system I have. It's a proof of concept so.... A full backup on a 
1gig Ethernet still takes a looooong time. But backing up even an 18GB disk on 
an Amiga via 100Base-t isn't too bad. And disk speeds of the era being what they 
were it's about all you can do anyway.
