Geographic redundancy
Organizational redundancy
If I can take care of those three items, it’s nearly certain I can meet most RPO and RTO needs. But I have never been in a situation in which I had an unlimited budget and capabilities, so I have always had to compromise. As a result, the order of the three items matters.
