I am planning on going to 1.8.x, so this does look very interesting.
It would definitely simplify things.

That one won't work for me. I'm not in control of the enterprise
backup software, so I don't even know when the backup will even happen
(I know it'll be within a many-hours-wide window). I asked the
sysadmin who is in charge of that software and he would have to
research whether it's even possible to run a script to freeze &
unfreeze the repository when the system gets to that server. Even if
it is possible, the implementation timeline will be long.
