I've got a no brainer for you, what is runspercycle?  I've rtfmed but
the explanation just dones't make sense to me.

At the moment I've got

Dumpcycle 4
Runspercycle 1
Tapecycle 10

Its set up so it runs every Mon-Thurs night and we have two weeks worth.
I've noticed that it appears to be doing level 0 on everything every
night, pressumably because it's a 400GB tape and the total data that's
backed up at the moment is considerably less.  Is there any way of
forcing amanda to only do the level 0 once and grab incrementals the
rest of the time, I thought I'd set it up like this, but something is
obviously wrong somewhere...

dumpcycle = maximum amount of time between level 0s of any particular DLE
          (disk list entry)
runspercycle = number of times you'll run amdump per dumpcycle
tapecycle = number of tapes you'll let amanda use, should be at least
            1.5*runspercycle*runtapes (preferable 2*)

For your setup, dumpcycle=1 week, runspercycle=4. Having runspercycle=1 is what's getting you level 0s every amdump.
