Create disaster recovery plan and runbook

[accuser]

Problem

BACKUP.md covers backup procedures but lacks a formal disaster recovery playbook with RTO/RPO targets.

Missing Elements

• Recovery Time Objective (RTO) testing
• Recovery Point Objective (RPO) verification
• Failover procedures documented but not automated
• No cross-region/off-site backup strategy
• Service priority matrix (which to restore first)

Recommendations

Create DISASTER_RECOVERY.md with:

1. Runbook for complete infrastructure loss

   • Step-by-step recovery procedures
   • Prerequisites and dependencies

2. Service priority matrix

   • Critical: step-ca, DNS
   • High: Prometheus, Grafana
   • Medium: Loki, application services

3. RTO/RPO targets

   • Define acceptable downtime per service
   • Define acceptable data loss window

4. Automated DR testing

   • Quarterly test schedule
   • Test scenarios and success criteria

5. Off-site backup strategy

   • Current backups reside on same infrastructure
   • Define off-site replication approach

Priority

Critical - essential for production readiness
