The 3-2-1 backup rule is pretty outdated in the world of cloud. You could have 3 complete copies of your data in different S3 buckets, but if they're all under the same account you've lost your blast radius protection

It's not outdated, you just actually need to follow it. 3 copies of data in separate S3 buckets is ignoring the "2" in the 3-2-1 rule: 2 different mediums, and also the "1" rule: 1 copy offsite. In the cloud era, offsite means not on the same cloud provider. Different mediums ideally means a non-cloud provider (e.g. a NAS at your office under your control).

It certainly is outdated, by that very example you just provied. Why can't my two backups be on two separate S3 providers?

If only there were a quick and easy way to replicate s3 buckets to an independent provider…

… on the Unix command line …

… to a cloud older than AWS…

… if only …

Wish I could upvote this comment account more. Too many people look for something new and shiny when trusty ol tools are sitting right there. :)

Well having backups help, but I certainly can’t migrate my infra to rsync.net on moments’ notice (or ever since rsync.net does storage and nothing else) so my customers aren’t affected.

Inflated egress costs might make this prohibitively expensive, $80 per TB at GCP and AWS

I don't think that technology exists. Sorry.

You replicate data to different clouds.
