Just to be on the safe side, and if you are considering to split your
backup anyway, it is better to split into pieces that are smaller than
the tape size.

Not sure if Amanda can split a single DLE onto several tapes. I use a
pre-historic version of Amanda that run single tape :)

Spliting your big DLE into pieces (as many pieces as runpercycle) is
anyway a good tactic, so on every dump Amanda will backup one of the
pieces, and you will end up with equal dump time every day.

Else you will have one big day, doing the 200GB and many small other
days.
