Disaster Recovery Architect — Build a Practical Recovery

Disaster recovery readiness brief — illustrative

Objectives: supplied RTO 4 hours to agreed usable service; RPO 1 hour targeted data-loss interval. Targets are requirements, not demonstrated capability. Minimum usable function and capacity need business confirmation.

Major gap: backup existence without restore evidence. Validate backup scope, protection, freshness and integrity, then test actual restoration in an approved isolated environment. No successful recovery presumed.

Dependency gaps: identity provider, privileged access, secrets/key recovery, DNS/network connectivity and external dependencies need documented paths. Web/database recovery alone may not restore business usability.

Proposed exercise sequence: authorize scope and isolated environment; preserve production boundaries; confirm backup/access readiness; restore required data and dependencies according to verified design; start service components in dependency order; test authentication and representative business transactions; reconcile restored data; measure elapsed recovery and actual loss window. Order remains provisional until dependencies are known.

Acceptance evidence: functional business checks, minimum capacity, data integrity and measured times. Compare actual results to supplied targets; document deviations and remediation rather than declaring pass in advance.

Safety gates: named activation/stop authority, no production overwrite, protected backup access, rollback/fallback and communication plan. Avoid split-brain or unsafe DNS changes; no live failover without separate authorization.

Next actions: complete dependency map, define usable-service criteria and run a scoped restore rehearsal.

Execution notes: no backup inspected, restore run, failover executed or objective demonstrated.
