But that was my point, what's considered a reasonable, rational risk scenario to an invest bank sounds to normal people to be similar to meteor level extinction events. Hence why the "backups have to cover everything possible" rule can't work, even if you add the caveat of "within rational scope", it is clear that Fortune 100 rational is SMB crazy. And what is F100 crazy, is still Wall St. rational. And what is Wall St crazy, is big government rational.
Backups shouldn't stop being backups based on the impression of rational scope. A backup is a backup, the scope that it covers is its coverage scope. Otherwise no SMB's backups would be a backup to the enterprise, for example. But the viewpoint of the observer should not be the determination of what is or isn't a backup, but rather an intrinsic property of the backup itself. Otherwise, you force a crazy scope to happen and someone mentions meteors - which was my point.
Lets agree on DR solutions being able (or striving to at least) cover disasters of whatever the scoped level is for a given business. With this in mind, avoidance techniques still have to target specific errors, while recovery solutions cover data loss from all of those, plus any other failure (within the scope, yes. Nothing will cover the failure of Earth remaining a livable planet).
