Given that no-one came up with a simple suggestion that fulfills your
requirements and none of the large number of backup packages available
seems to fit the bill, I think that Paul's suggestion to change your
requirements was not inappropriate.
If I were you, I'd buy an usb hub and housings/adapters for all the usb
disks required for the backup. Then I'd combine them to a lvm or raid0
and use *rsync* or a similar tool to backup the system to all disks
attached at once.
The only other /practical/ option that /I/ can think of is to buy
another machine similar or identical to the production one and use that
for backup, again using rsync or a similar tool.
NB: Have you thought about how much work and how long it will take to
*verify* your backup, if it is spread over so many disks, each attached
(I strongly recommend to verify one's backup occasionally.)
