There are a couple of approaches you could use, depending on your exact
requirements and the level of complexity you're willing to cope with.
The two main classes of solution are

 - run a shared filesystem underneath rabbit, with a hot standby if
   one server should fail. This separates data availability from
   service availability, and reduces the "no service" window to the
   failover interval.

 - run two servers and route *all* traffic through *both*, deduping
   at the receiving client. This gives as many nines of uptime as you
   want, at a cost in administrative complexity and bandwidth wastage

We've been talking about this stuff to various people recently so have
some illustrations of what we mean that might be useful: see

  Tony
