That's great, but totally non-responsive to the question.

Right of erasure means you have to delete them on request.

From backups too...

I love seeing the same lie repeated over and over: You do not have to delete them from backups. Anyone wasting time on "rewriting backups" should be fired from their job.

You just need a process in place so you don't restore those same users if ever restoring backups.

Interesting. I’ve spent a fair bit of my life lately looking at this problem and come to the opinion that anyone trying to systematically prevent deleted users from being restored should be fired.

Different strokes I suppose.

Can we agree at least that you have to account for deletion in your backup strategy?

You should account for deletion, but in general this stuff doesn't keep me up at night.

In the rare event you restore deleted users, and even rarer, if they actually notice, just tell them you screwed up.

My understanding is that you can refuse to comply with erasure if it's for a "legitimate business purpose." Every company has a legitimate business purpose for backups that aren't kept indefinitely.
