That was Jason&#x27;s use case that he had in mind, but for plenty of people the situation is the exact opposite but the principle remains.<p>Having two cloud providers would work assuming they don&#x27;t share any critical infra-structure and assuming that it is not the same set of employees that have access to both systems. Also helps if you have a totally separate set of credentials for the back-up system and if that back-up system can only be unlocked by very senior people (preferably execs) after a catastrophe of suitable magnitude hits.<p>Whether you store your primary in the cloud or your back-up in the cloud the story is the same: have a copy somewhere else.<p>Finally: the only real back-up is one that is off-line. So from that (ok, ultra-paranoid) viewpoint it would be best if you actually went to an off-line medium to store your data in such a way that nobody can wipe it all out without physically destroying all copies.<p>All this of course after suitably weighing the importance of the data.
