Disaster Recovery for a Platform That Hadn't Tested Recovery

A platform that had grown to a size where its leadership recognized that the disaster recovery posture documented in their runbooks didn't necessarily correspond to operational reality. The runbooks existed. The recovery procedures had been written. Nobody had ever actually executed them under conditions that resembled disaster.

The platform held customer data and operated workloads that mattered to its customers' businesses. The leadership's exposure if recovery turned out to be slower or less complete than the runbooks claimed was material. The engagement was to verify the posture honestly and remediate where verification revealed gaps.

A disaster recovery engagement structured around actual rehearsal.

Posture audit — The current state was documented honestly — what was backed up, where, with what frequency, with what restoration testing history. The audit revealed gaps the team had suspected and some they hadn't.

Backup strategy remediation — Backup coverage was extended to the gaps the audit had revealed. Backup frequency was adjusted to match the recovery point objectives the platform's customer commitments implied. Backups were validated for restoration capability — backups that can't be restored aren't backups.

Recovery runbook rebuild — The runbooks were rewritten against the current platform topology rather than the topology of two years prior. Each procedure was written by someone who would actually execute it, not as a documentation exercise.

Recovery rehearsal — The team executed full recovery procedures against a parallel environment. Findings from the rehearsal — steps that didn't work as documented, procedures that took longer than expected, dependencies that weren't surfaced in the runbook — were addressed in the runbooks and in the procedures themselves.

Cross-region backup destination — Backups had been held in the same region as the primary infrastructure. The architecture was extended so that backups were held in a separate region, providing genuine recovery capability against regional cloud-provider incidents.

Periodic rehearsal cadence — A schedule was established for ongoing recovery rehearsal — quarterly verification that the procedures still worked, that the team still knew them, and that the platform's evolution hadn't introduced new gaps.

The platform's disaster recovery posture moved from documented to verified. The leadership's exposure on this dimension reduced materially. The team gained the operational confidence that comes from having actually executed the procedures rather than having only written them.

The engagement also revealed two latent issues unrelated to disaster recovery — a dependency that hadn't been documented and a backup destination that had been silently misconfigured for several months. Both were addressed alongside the primary work.
