# Disaster Recovery Procedures
|
|
|
|
**Last Updated**: 2025-01-27
|
|
**Status**: Production Ready
|
|
|
|
## Overview
|
|
|
|
This document outlines disaster recovery (DR) procedures for The Order platform, including Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO).
|
|
|
|
## RTO/RPO Definitions
|
|
|
|
- **RTO (Recovery Time Objective)**: 4 hours
|
|
- Maximum acceptable downtime
|
|
- Time to restore service after a disaster
|
|
|
|
- **RPO (Recovery Point Objective)**: 1 hour
|
|
- Maximum acceptable data loss
|
|
- Time between backups
|
|
|
|
## Backup Strategy
|
|
|
|
### Database Backups
|
|
- **Full Backups**: Daily at 02:00 UTC
|
|
- **Incremental Backups**: Hourly
|
|
- **Retention**: 30 days for full backups, 7 days for incremental
|
|
- **Location**: Primary region + cross-region replication
|
|
|
|
### Storage Backups
|
|
- **Object Storage**: Cross-region replication enabled
|
|
- **WORM Storage**: Immutable, no deletion possible
|
|
- **Backup Frequency**: Real-time replication
|
|
|
|
### Configuration Backups
|
|
- **Infrastructure**: Version controlled in Git
|
|
- **Secrets**: Stored in Azure Key Vault with backup
|
|
- **Kubernetes Manifests**: Version controlled
|
|
|
|
## Recovery Procedures
|
|
|
|
### Database Recovery
|
|
|
|
1. **Identify latest backup**
|
|
```bash
|
|
ls -lt /backups/full_backup_*.sql.gz | head -1
|
|
```
|
|
|
|
2. **Restore database**
|
|
```bash
|
|
gunzip < backup_file.sql.gz | psql $DATABASE_URL
|
|
```
|
|
|
|
3. **Apply incremental backups** (if needed)
|
|
```bash
|
|
for backup in incremental_backup_*.sql.gz; do
|
|
gunzip < $backup | psql $DATABASE_URL
|
|
done
|
|
```
|
|
|
|
### Service Recovery
|
|
|
|
1. **Restore from Git**
|
|
```bash
|
|
git checkout <last-known-good-commit>
|
|
```
|
|
|
|
2. **Rebuild and deploy**
|
|
```bash
|
|
pnpm build
|
|
kubectl apply -k infra/k8s/overlays/prod
|
|
```
|
|
|
|
3. **Verify health**
|
|
```bash
|
|
kubectl get pods -n the-order-prod
|
|
kubectl logs -f <pod-name> -n the-order-prod
|
|
```
|
|
|
|
### Full Disaster Recovery
|
|
|
|
1. **Assess situation**
|
|
- Identify affected components
|
|
- Determine scope of disaster
|
|
- Notify stakeholders
|
|
|
|
2. **Activate DR site** (if primary region unavailable)
|
|
- Switch DNS to DR region
|
|
- Start services in DR region
|
|
- Restore from backups
|
|
|
|
3. **Data recovery**
|
|
- Restore database from latest backup
|
|
- Restore object storage from replication
|
|
- Verify data integrity
|
|
|
|
4. **Service restoration**
|
|
- Deploy all services
|
|
- Verify connectivity
|
|
- Run health checks
|
|
|
|
5. **Validation**
|
|
- Test critical workflows
|
|
- Verify data consistency
|
|
- Monitor for issues
|
|
|
|
6. **Communication**
|
|
- Update status page
|
|
- Notify users
|
|
- Document incident
|
|
|
|
## DR Testing
|
|
|
|
### Quarterly DR Tests
|
|
- Test database restore
|
|
- Test service recovery
|
|
- Test full DR procedure
|
|
- Document results
|
|
|
|
### Test Scenarios
|
|
1. **Database corruption**: Restore from backup
|
|
2. **Region failure**: Failover to DR region
|
|
3. **Service failure**: Restore from Git + redeploy
|
|
4. **Data loss**: Restore from backups
|
|
|
|
## Monitoring and Alerts
|
|
|
|
- **Backup failures**: Alert immediately
|
|
- **Replication lag**: Alert if > 5 minutes
|
|
- **Service health**: Alert if any service down
|
|
- **Storage usage**: Alert if > 80% capacity
|
