# Backup & Recovery

## Overview
The Backup & Recovery service will provide comprehensive data protection, disaster recovery, and business continuity capabilities for the stock-bot platform. It will ensure that critical data and system configurations are preserved, with reliable recovery options in case of system failures, data corruption, or catastrophic events.

## Planned Features

### Backup Management
- **Automated Backups**: Scheduled backup of all critical data
- **Incremental Backups**: Efficient storage of incremental changes
- **Multi-tier Backup**: Different retention policies by data importance
- **Backup Verification**: Automated testing of backup integrity
- **Backup Catalog**: Searchable index of available backups

### Recovery Capabilities
- **Point-in-time Recovery**: Restore to specific moments in time
- **Granular Recovery**: Restore specific objects or datasets
- **Self-service Recovery**: User portal for simple recovery operations
- **Recovery Testing**: Regular validation of recovery procedures
- **Recovery Performance**: Optimized for minimal downtime

### Disaster Recovery
- **Cross-region Replication**: Geographic data redundancy
- **Recovery Site**: Standby environment for critical services
- **Failover Automation**: Scripted failover procedures
- **Recovery Orchestration**: Coordinated multi-system recovery
- **DR Testing**: Regular disaster scenario testing

### Data Protection
- **Encryption**: At-rest and in-transit data encryption
- **Access Controls**: Restricted access to backup data
- **Retention Policies**: Compliance with data retention requirements
- **Immutable Backups**: Protection against ransomware
- **Air-gapped Storage**: Ultimate protection for critical backups

## Planned Integration Points

### Data Sources
- Platform databases (MongoDB, PostgreSQL)
- Object storage and file systems
- Service configurations
- Message queues and event streams
- User data and preferences

### System Integration
- Infrastructure as Code systems
- Monitoring and alerting
- Compliance reporting
- Operations management tools

## Planned Technical Implementation

### Technology Stack
- **Backup Tools**: Cloud-native backup solutions
- **Storage**: Object storage with versioning
- **Orchestration**: Infrastructure as Code for recovery
- **Monitoring**: Backup health and status monitoring
- **Automation**: Scripted recovery procedures

### Architecture Pattern
- Centralized backup management
- Distributed backup agents
- Immutable backup storage
- Recovery validation automation
