# Disaster Recovery Specification
|
|
|
|
## Overview
|
|
|
|
Disaster recovery procedures and backup strategies.
|
|
|
|
## Backup Strategies
|
|
|
|
### Database Backups
|
|
|
|
**Full Backups**: Daily full database dumps
|
|
**Incremental Backups**: Continuous WAL archiving (PostgreSQL)
|
|
**Storage**: Off-site backup storage
|
|
**Retention**: 30 days full, 7 days incremental
|
|
|
|
### Application Backups
|
|
|
|
**Configuration**: Backup configuration files
|
|
**Secrets**: Secure backup of secrets
|
|
**Code**: Version control (Git)
|
|
|
|
## Recovery Procedures
|
|
|
|
### Recovery Scenarios
|
|
|
|
**1. Database Corruption**:
|
|
- Restore from latest backup
|
|
- Replay WAL logs
|
|
- Verify data integrity
|
|
|
|
**2. Service Failure**:
|
|
- Restart services
|
|
- Verify health
|
|
- Check logs
|
|
|
|
**3. Data Center Failure**:
|
|
- Failover to secondary region
|
|
- Restore from backups
|
|
- Verify functionality
|
|
|
|
### Recovery Testing
|
|
|
|
**Frequency**: Quarterly
|
|
**Tests**: Restore from backups, verify data integrity
|
|
|
|
## RTO/RPO Targets
|
|
|
|
**RTO (Recovery Time Objective)**: 1 hour
|
|
**RPO (Recovery Point Objective)**: 5 minutes (max data loss)
|
|
|
|
## Multi-Region Failover
|
|
|
|
### Failover Strategy
|
|
|
|
**Primary Region**: Active services
|
|
**Secondary Region**: Standby/replica services
|
|
**Failover**: Automatic or manual failover
|
|
|
|
### Data Replication
|
|
|
|
**Method**: Database replication, data synchronization
|
|
**Latency**: Acceptable replication lag
|
|
**Consistency**: Eventual consistency acceptable
|
