Stale & Duplicate Data

SL-04

Data nobody uses and copies nobody tracks. Both expand the breach blast radius and the erasure obligation while delivering no value — which makes them the cheapest risk reduction available.

Beyond the first copy

Why this matters more than it looks

12.3 Cr records have not been accessed in over a year, and 24.5 Cr exist only as redundant copies. Every one of them is still personal data: still within scope of an access request, still within scope of an erasure request, and still exposed in a breach. Removing them reduces obligation and risk simultaneously, which very little else in compliance does.

Not accessed within the threshold

Candidates for archival to secure storage or, where retention has also lapsed, for deletion.
