Define recovery priorities
List applications and infrastructure dependencies in recovery order, with owners, RPO, RTO, and required upstream services. Recovery sequence matters because storage, identity, DNS, networking, virtualization, and applications depend on one another.
Document authoritative data copies
For each protected workload, identify the primary copy, replicated copy, backup copy, retention, and the procedure for selecting a recovery point. Ambiguity here becomes dangerous during a real incident.
Write executable steps
A runbook should contain concrete prerequisites, access requirements, validation checks, failover steps, failback considerations, communications, and stop conditions—not only architecture diagrams.
Include failure and rollback branches
Document what to do when replication is unavailable, a restore fails, capacity is insufficient, credentials are unavailable, or the planned recovery site has a dependency problem.
Test and update it
Run tabletop exercises and technical recovery tests at a cadence appropriate to the business. Record actual recovery times, gaps, and ownership changes, then update the runbook immediately.
