If you only have one cache, and this fails, and you need to restore the
whole repository(ies): then yes. You have a problem.

        But if you have two cache servers, perhaps you would not even notice
while the second one is getting the whole repository(ies).

        But I am not sure if I am following your and Russ rationale.
