The original question was the same, and the answer was that you can do
that with RAIT with the third (parity) drive set to /dev/null, although
that has certain disadvantages, too.

This capability is something we'd like to add in a more permanent sense
(so e.g., full dumps get written to each tape, instead of blockwise
striping), but it's a fairly fundamental change and will not be here too
soon.
