If you accidentally delete something, how long does it take for the delete to propagate to all of your geographically separated datacenters? You need some sort of point-in-time snapshots to be able to recover from accidents and silent corruption.

Sounds like you are the second type of people mentioned in the article.

that's not really the same thing, what you are describing is redundancy so failure in one (or more) place doesn't bring the system down. Backups are about preventing data loss. Data loss can happen in many different ways, not just a system crashing and burning. It can be deliberately/accidently done such that it would be sync'd everywhere.
