> I find that if you put a decent bit of engineering effort into that "disaster recovery" synchronisation, it can often act as the main or only synchronisation process for quite a lot of systems.
Another benefit is that you get to exercise those disaster recovery mechanisms regularly as part of the normal functioning of the system, rather than a specialized path that is only rarely exercised (and thus may be broken when you need it the most).
