Erasure is not an absolute delete button

The right to erasure is real and it is conditional.

It applies in defined circumstances and gives way where there is a legal obligation to keep the data, an ongoing contract, or a legal claim. It also collides with practical reality in backups, which cannot be selectively edited. The workable answer is usually to remove from live systems and let the backup cycle age out, documented as such rather than pretended away.
