I'm not complaining of backup. I'm complaining that a product that creates an AD infrastructure (so to speak) but does not allow another server to take over all roles and responsibilities is (IMHO) not a good choice.

I can see where it would be possible for such a disaster to put a "small" business "out of business". There are many small companies out there that could not survive (financially) a loss of everything like that.

The whole point is that a small company probably does not have any dedicated IT Staff and is probably installed by the owner him/herself and that's the end of it and they don't know better. I just think it's not a good choice.
