Thinking of using ZFS/FBSD for a backup system

go back to computability 301.  the complexity of the systems we are all
talking about are many many orders of magnitude beyond anything for
which we can [dis]prove simple termination.  so wind the rhetoric down a
notch, please

if you want the only guaranteed state people here can give you, unplug
your machine.

otherwise, you'll just have to accept experience, empirical testing,
vetted advice, and wisdom.
