Yep. It's brittle but it works. It's brittle because if the production
cluster topology changes I have some work to do (since the copied
SSTables will now not match the static mapping until I manually update

I've yet to find a simpler way to do this (the LocationInfo CF stores
(token, inetaddress) pairs, and those simply don't automagically
transfer to a backup cluster).
