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.
