[INFRA-4] Implement Database Backup Strategy

[MVPandey]

💾 DATABASE BACKUP & RECOVERY

Priority: HIGH - Data Protection

Problem

No automated database backup strategy in place. Risk of data loss without recovery mechanism.

Solution

Implement automated PostgreSQL backup with retention policies and recovery procedures.

Backup Script

#!/bin/bash
# scripts/backup-database.sh
BACKUP_DIR="/backups/postgresql"
DATE=$(date +%Y%m%d_%H%M%S)
BACKUP_FILE="cae_backup_${DATE}.sql"

# Create backup
pg_dump -h $DB_HOST -U $DB_USER $DB_NAME > "${BACKUP_DIR}/${BACKUP_FILE}"

# Compress backup
gzip "${BACKUP_DIR}/${BACKUP_FILE}"

# Upload to S3 (optional)
aws s3 cp "${BACKUP_DIR}/${BACKUP_FILE}.gz" s3://cae-backups/

# Cleanup old backups (keep 30 days)
find ${BACKUP_DIR} -name "*.gz" -mtime +30 -delete

Docker Backup Service

# docker-compose.backup.yml
version: '3.8'
services:
  backup:
    image: postgres:15
    volumes:
      - ./scripts:/scripts
      - backup_data:/backups
    environment:
      - PGPASSWORD=${DATABASE_PASSWORD}
    command: |
      sh -c "
      while true; do
        /scripts/backup-database.sh
        sleep 86400  # Daily backups
      done"

Implementation Steps

• Create automated backup scripts
• Setup backup scheduling
• Implement retention policies
• Add backup verification
• Create recovery procedures
• Test backup/restore process

Acceptance Criteria

• Daily automated backups
• 30-day retention policy
• Backup verification process
• Documented recovery procedures
• Tested restore capability

Effort: Medium (2-3 days)
