Why would anyone back up data in the manner you’re saying? That’s dumb.
Don’t split the data across multiple logical locations, keep it logically contained. A raid designed for availability is better than a single external hard drive but that isn’t what is being talked about.
3 2 1 means keeping multiple copies of the SAME data on multiple media types in multiple locations so you remove a single point of failure.
You misunderstand the intent then.
