- **Incremental backups** for changed data
- **Version control** for critical files

### Cloud Backups
- **Encrypted cloud storage** for critical data
- **Automated sync** for important documents
- **Disaster recovery** procedures

## Monitoring & Maintenance

### Health Monitoring
- **SMART data** monitoring for drive health
- **Temperature monitoring** for thermal management
- **Performance metrics** for optimization

### Maintenance Schedule
- **Monthly**: Drive health checks
- **Quarterly**: Firmware updates
- **Annually**: Physical cleaning and inspection

## Integration

### Container Orchestration
- **Portainer stacks** deployed on NAS systems
- **Docker volumes** for persistent storage
- **Network shares** for container data

### Media Services
- **Plex Media Server** for streaming
- **Arr suite** for media management
- **Backup services** for data protection
