Stress-test a retention schedule cut by proving that each delete window and hold rule can place removals inside the planned lane, survive override pressure, and avoid trapping operators inside a green retention slide that hides long-lived exceptions.
Retention schedule cuts often list a calendar while leaving restore behavior, override authority, and abort ownership implicit. Those edges decide whether a late keep ask stops inside the policy or leaves a broken archive live under production load. The exercise should follow actual storage tools, retention exports, and on-call paths rather than a clean compliance deck.
Inventory the retention path
List every data class with its hold window, delete rule, override behavior, owners, and notification channels. Mark paths that cannot reverse without a manual archive edit. Attach the last three retention incidents with raw timelines and any waivers. Include the source of truth for open keep counts during the observation window.
Define the phases for detect, hold, delete, abort, and communicate. Each phase needs an owner and an exit condition. Write the point after which a stuck retention hold would require a different procedure, then review whether that action is still permitted. Capture maximum acceptable service friction in measurable units, including which cohorts are excluded from the hold and why.
Include the calendar of known events for the next two quarters: release peaks, audit windows, and partner cutovers that shrink the usable change window. A retention budget that ignores those dates will look calm until the week they land.
Failure drills
- A minority high-volume store keeps a side-channel while the aggregate retention dashboard stays green.
- A restore has already left a partner surface without a trusted delete state.
- The primary storage dashboard lags beyond the planned observation window.
- An operator skips a hold gate because a release is close.
- Automated and human holds collide under the new delete rule.
- Abort authority is unclear at week end and the page lands on the wrong retention.
For each drill, identify detection time, service impact, containment, and the authority to force a retention rollback. Require commands and dashboard links in the runbook. A statement that monitoring will catch it does not establish which alert fires or who receives it.
Prove retention changes are timed and owned
Run the package in Pingpong with privacy, platform, legal, and finance seats. Ask platform which storage decision becomes unsafe first if deletes still stick after the claimed window. Ask legal whether contracts can absorb a forced override. Ask privacy to show the exact retention version or storage export used as the exit condition.
