That’s all well and good for weather data, but if anything in your backup is in any way related to user behaviors or transactions, immutability is a crime.

Immutability in this context doesn't mean "kept forever", it just means the permission to hard-delete is separate from soft-delete.

GDPR requires that good data-stewards keep backups:

the controller and the processor shall implement... the ability to restore the availability and access to personal data in a timely manner in the event of a physical or technical incident

It would be inappropriate, for instance, to store user data on the blockchain.

It also requires that user data can be hard-deleted on command. The ability to wipe data from backups needs to be kept close at hand.
