## What I do - Create comprehensive DR plans - Define RTO and RPO objectives - Test recovery procedures regularly - Implement failover and failback systems - Design for various disaster scenarios - Ensure business continuity ## When to use me When preparing for system failures, designing resilient infrastructure, or creating business continuity plans. ## Key Metrics ### RTO (Recovery Time Objective) - Maximum acceptable downtime - How long can the system be down? - Typically defined in hours ### RPO (Recovery Point Objective) - Maximum acceptable data loss - How much data can be lost? - Typically defined in minutes/hours ### SLA (Service Level Agreement) - Committed availability - Downtime allowances per year: - 99% = 3.65 days/year - 99.9% = 8.76 hours/year - 99.99% = 52.6 minutes/year - 99.999% = 5.26 minutes/year ## DR Strategies ### Backup & Restore - Regular backups to offsite location - Automated restore testing - Pros: Simple, low cost - Cons: Higher RTO ### Pilot Light - Core services running minimal - Scale up on failover - Pros: Faster than backup - Cons: More complex ### Warm Standby - Scaled-down version running - Quick scale on failover - Pros: Faster recovery - Cons: Higher cost ### Multi-Region Active-Active - Full deployment in multiple regions - Traffic distributed - Pros: Fastest recovery, highest availability - Cons: Most expensive, complex ## Disaster Recovery Plan ### Assessment - Identify critical systems - Document dependencies - Assess risks and impacts - Define recovery priorities ### Prevention - Redundancy - Monitoring - Alerts - Security - Regular maintenance ### Detection - Monitoring systems - Health checks - Alerting - Incident response team ### Response - Runbooks - Escalation procedures - Communication plan - Documentation ### Recovery - Documented procedures - Tested steps - Team responsibilities - Verification steps ## Data Protection ### Backup Strategies - Full backups - Incremental backups - Differential backups - Continuous replication ### Backup Locations - On-site (fast restore) - Off-site (disaster protection) - Cloud storage - Air-gapped backups ### Testing - Restore testing - Failover testing - Full DR exercises - Document results
