Because you're holding back: "THIS" communicates that you strongly agree, but we the readers don't know why. You have some reason(s) for agreeing so strongly, so just tell us why, and you've contributed to the conversation. Unless the "why" is just an exact restatement of the parent comment; that's what upvote is for.
That's a form of hardware failure where the failure domain is a data center or region. It is always good to store enough redundant data outside of whatever failure domains you want to consider in your planning. That might be a device, a server, a rack, a room, a data center, a region or a country/regulatory domain.
Non-local storage is definitely worthwhile there. Snapshots can have additive value there because they may be more coherent states.
