Right to erasure.

the two-minute refresher

• Applies when data is no longer needed, consent is withdrawn and more; refusals exist (legal obligations, legal claims).
• Hard because data is fragmented: databases, search, caches, files, analytics, third parties, backups, logs.
• Build a data map first, then a deletion service that fans out to each system and verifies.
• Backups and logs usually expire by policy rather than being edited; record every deletion in an audit trail.
