You're almost right. I used the similar solution when I used vinum raid-5. The only "but" is that dd(1) cannot be used. I got away with newfs,dump,restore. Also, the system disk is "dumb", it can be copied once and saved offline. However, if the "almost-hot" backup is needed, nightly mirror is a feasible solution. --Roman Shterenzon, UNIX System Administrator and Consultant [ Xpert UNIX Systems Ltd., Herzlia, Israel.
