## Overview

Configure database replication for disaster recovery, load distribution, and high availability. Covers master-slave, multi-master replication, and monitoring strategies.

## When to Use

- High availability setup
- Disaster recovery planning
- Read replica configuration
- Multi-region replication
- Replication monitoring and maintenance
- Failover automation
- Cross-region backup strategies

## Quick Start

**PostgreSQL - Configure Primary Server:**

```sql
-- On primary server: postgresql.conf
-- wal_level = replica
-- max_wal_senders = 10
-- wal_keep_size = 1GB

-- Create replication user
CREATE ROLE replication_user WITH REPLICATION ENCRYPTED PASSWORD 'secure_password';

-- Allow replication connections: pg_hba.conf
-- host    replication     replication_user   standby_ip/32    md5

-- Enable WAL archiving for continuous backup
-- archive_mode = on
-- archive_command = 'test ! -f /archive/%f && cp %p /archive/%f'
```
