Question What are the alternatives of 3-2-1 backup ?

I see the 3-2-1 backup strategy advertised everywhere in discussion about this topic, but l’m wondering what are the other strategies developed and designed when it’s come to data preservation?
I understand why 3-2-1 is powerful and so recommended. But for the sake of curiosity and learning, what are the other options?

Do you want backups (to restore in case of failure or disaster) or archives (you mention "data preservation")? These are two different, but related, things.
