I pay $25/month per a single hosted FogBugz user. I believe you can build in reasonable disaster recovery procedures at "reasonable cost" given these kinds of price points. I don't see any technical obstacles — in fact I think Fog Creek used to write about how they have hot backups (replication, I'd assume) in various geographical locations.
And I do not want to host FogBugz myself, in fact I'm paying exactly for the comfort of not having to plan for failures in the case of FogBugz.
Incidentally, we run a SaaS company. Our disaster recovery worst-case scenario means recreating our services from scratch in any Amazon AWS datacenter on Earth in less than 4 hours. Yes, we have an easier job, because we do not store a lot of transactional user data. But our service is also way, way cheaper than FogBugz.
