What you want is for the volume and its data to effectively be pruned as
soon as it's written, which isn't the easiest thing to do.  In your
situation, what I would be doing is set up the retention periods the way
you're going to want them when you go live, and then -- hey, you're
*testing*.  Just manually purge the tape for now.  Really.  It's simpler
than first trying to come up with a configuration to automatically do
something you'd never do in production, and then trying to make sure you
get every last trace of it out again before you go live.
