250 gig would be a bit much to backup over the wire
your system with external disks to me sounds like a good idea, fast, easy , off site, fire proof case
except for one thing , and that is going back in time isn't much of an option
eg , if your rotation is a daily backup to disk 1, then disk 2, while disk 3 is off premises, the next week you rotate 3and 2 while 1 is off, and then 3 and 1 , while # 2 is off
that will give you 1 week to go back too
let's say you have form of data corruption on a non frequently used file ( not to far fetched in medical ) , you would have to see the corruption within 7 days of it occuring, or else it would be on all your backups...
i would recommend you keep the daily rotations going with the 3 disks, but keep the disks on site, and add a tape backup at the end of the work week...then keep that tape off site
could work with 4 tapes, or more if you want to store a snapshot per month...(typical places with expensive data , like big plants or accounting places would rotate daily, weekly , monthly, and at the end of each year, the full year set get's stored, and all the others get replaced and destroyed)
