Sorry, but RAID is absolutely, positively NOT a backup solution. It is simply a way to have one particular storage set survive a drive failure. If a natural event strikes the RAID set, it's just as dead as the next drive. And cloud will struggle to keep up with the needs of photographers, particularly with respect to upload bandwidth.
