Data Erasure

Data Management

Data Retention Data Controller DSAR Right to Erasure

Deletion or irreversible removal of personal data across systems, including backups where feasible.

Definition

Data erasure is the process of deleting personal data from primary systems, derived datasets, and, where feasible, backups and archives, with documented exceptions and audit trails.

In plain English Deletion or irreversible removal of personal data across systems, including backups where feasible.

Why this matters

Why it matters: Effective erasure requires data mapping; partial deletion can leave traces that still identify users.

Example

Example: Replace identifiers with null or irreversible tokens while preserving aggregate statistics.
