4.8. Disaster Recovery
💡 First Principle: Disaster recovery is not backup at scale—it's a plan for restoring business operations when an entire site or major system is unavailable. DR planning starts with the business (RTO and RPO requirements) and works backward to technical implementation. A DR plan that hasn't been tested has unknown gaps.
The worst time to discover your DR plan doesn't work is during an actual disaster.
