Executive Summary

This document defines Recovery Time Objectives (RTO), Recovery Point Objectives (RPO), disaster recovery procedures, and rollback criteria for the KYRA AI MDR platform. The DR strategy prioritizes customer data protection, service availability, and compliance requirements across all supported service tiers.

Critical Requirements:

• Enterprise tier: RTO 15 minutes or less, RPO 5 minutes or less
• Professional tier: RTO 30 minutes or less, RPO 15 minutes or less
• Standard tier: RTO 60 minutes or less, RPO 30 minutes or less
• Quarterly DR drills with documented runbooks
• Zero data loss for tenant configurations, incidents, and audit logs

Analytics Database	15 min	30 min	30 min	60 min	60 min	2 hr
Object Storage	N/A	0 min	N/A	0 min	N/A	0 min

Composite Service Availability Targets

Service Tier	Overall RTO	Overall RPO	Monthly SLA	Annual Downtime
Enterprise	15 min	5 min	99.95%	4.38 hours
Professional	30 min	15 min	99.9%	8.76 hours
Standard	60 min	30 min	99.5%	43.8 hours

Critical Path Recovery Order

Minimum service recovery order for tenant access:

1. Primary database (tenant authentication and data)
2. Cache layer (session management)
3. Identity provider or emergency admin bypass
4. Customer portal / API
5. Event ingestion (resume data collection)
6. Event processing pipeline
7. AI analysis
8. Analytics and reporting

Infrastructure Resilience

Multi-Region Architecture

• Primary region with multi-availability-zone deployment
• DR region with standby infrastructure
• Per-tenant data residency compliance enforcement
• Cross-region data replication for critical services

High Availability

• Minimum 3 replicas for critical services across availability zones
• Anti-affinity rules to prevent single-point-of-failure
• Horizontal auto-scaling based on load metrics
• Pod disruption budgets to maintain availability during maintenance

Database Resilience

• Multi-AZ deployment with synchronous standby
• Read replicas in primary and DR regions
• Automated daily backups with 7-day point-in-time recovery
• Automatic failover (60-120 seconds)

Cache Resilience

• Clustered deployment with automatic failover
• Daily snapshots for recovery
• 15-second failure detection

External Dependencies

Dependency	Purpose	Fallback Strategy
Identity Provider	SSO authentication	Emergency admin access
Primary AI Provider	AI threat analysis	Fallback to secondary provider, then self-hosted
Secondary AI Provider	Backup AI analysis	Fallback to primary provider, then self-hosted
Self-hosted AI	Air-gap AI fallback	No external dependency
Encryption Key Management	Key management	Cross-region key replication
Observability Platform	Monitoring	On-premise monitoring instance

---

Backup Schedule

Data Type	Frequency	Retention	Recovery Method
Database (continuous)	Continuous	7 days	Point-in-time restore
Database (full)	Daily	30 days	Full restore
Cache snapshots	Daily	7 days	Import from snapshot
Analytics data	Daily	90 days	Restore from backup
Application config	On change	90 days	Configuration reapply
Secrets	Daily	30 days	Secrets manager restore

Cross-Region Failover

Automatic Triggers

• Health check failures for more than 3 minutes across all primary region endpoints
• RTO breach imminent with manual trigger before SLA violation
• Region-wide outage confirmed by cloud provider

Failover Procedure (30-minute target)

1. Promote DR region database replica to primary
2. Update DNS routing to DR region
3. Scale up DR region services
4. Update identity provider callback URLs
5. Validate service health across all components

Failback Procedure

1. Confirm primary region health across all services
2. Resynchronize data from DR to primary (if needed)
3. Gradually shift traffic (20% / 40% / 60% / 80% / 100%)
4. Scale down DR region after 24-hour monitoring period

Quarterly DR Drills

Schedule & Scope

Frequency: Every 90 days (March, June, September, December) Duration: 4 hours planned window Impact: No production service disruption (test environment simulation)

Drill Types (Rotating):

• Q1: Regional failover simulation
• Q2: Database corruption and point-in-time recovery
• Q3: Security incident response (simulated breach)
• Q4: Complete infrastructure rebuild

Drill Validation Checklist

• All API services available within target RTO
• Data integrity confirmed (zero data loss)
• AI analysis workflows resuming within 20 minutes
• Event ingestion restored within 10 minutes
• Analytics processing resumed within 25 minutes
• Customer impact less than 5 minutes of degraded service
• All monitoring alerts fired correctly with less than 2-minute detection
• Runbook accuracy within 10% deviation from documented procedures

Drill Reporting

Distribution: CTO, VP Engineering, VP Customer Success, Security Lead SLA: Report delivered within 5 business days of drill completion

Required Sections:

1. Executive summary (pass/fail, key metrics, customer impact)
2. Detailed timeline (planned vs. actual for each phase)
3. Performance metrics (RTO/RPO achieved vs. targets per service)
4. Gap analysis (process deviations, tool failures)
5. AI agent recovery performance
6. Inter-service communication analysis
7. Database recovery validation
8. Security control effectiveness
9. Action plan (improvements with owners and deadlines)
10. Risk assessment (updated based on drill findings)
