Disaster Recovery

​

Recovery Objectives

​

Backup Strategy

• PostgreSQL Backups (GCP)
  • Automated point-in-time backups every 15 minutes
  • Daily full snapshots stored for 30 days
• Cloudflare R2 Objects
  • Versioned storage for all key documents (invoices, attachments)
  • Lifecycle policy to retain 90 days of object versions
• Xano Metadata & Logs
  • Daily exports of audit logs and configuration stored in R2
  • Retention for 180 days

​

Failover & Continuity

• Multi-Region Read Replicas
  • PostgreSQL read replicas in secondary GCP regions for failover
• Worker Redeployment
  • Cloudflare Workers automatically redeployed across edge nodes
• API Layer Resilience
  • Xano deployed on multiple GCP zones; automatic traffic rerouting on failure
• Auxiliary Service Redundancy
  • Railway and Render services configured with health checks and retry policies

​

Incident Response Process

1. Detection & Alerting
   • Automated monitoring triggers alerts for service errors, latency spikes, and downtime
   • Incident tickets created in PagerDuty (or equivalent)
2. Containment & Mitigation
   • Traffic rerouted to healthy regions or fallback endpoints
   • Read-only mode activated if necessary to preserve data integrity
3. Recovery & Restoration
   • Data restored from nearest snapshot to meet RPO
   • Services restarted in failover region within RTO targets
4. Post-Incident Review
   • Root cause analysis documented
   • Action items tracked and prioritized in backlog
   • DR plan updated based on lessons learned

​

Testing & Validation

• Quarterly DR Drills
  • Simulated outages to validate failover procedures and recovery scripts
• Backup Restore Tests
  • Monthly restore exercises from R2 and PostgreSQL snapshots
• Documentation Reviews
  • DR plan reviewed semi-annually to incorporate infrastructure or process changes
