Backup and Disaster Recovery
Table of Contents
Overview
Design and implement comprehensive backup and disaster recovery strategies to ensure data protection, business continuity, and rapid recovery from infrastructure failures.
When to Use
- Data protection and compliance
- Business continuity planning
- Disaster recovery planning
- Point-in-time recovery
- Cross-region failover
- Data migration
- Compliance and audit requirements
- Recovery time objective (RTO) optimization
Quick Start
Minimal working example:
# postgres-backup-cronjob.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: backup-script
namespace: databases
data:
backup.sh: |
#!/bin/bash
set -euo pipefail
BACKUP_DIR="/backups/postgresql"
RETENTION_DAYS=30
DB_HOST="${POSTGRES_HOST}"
DB_PORT="${POSTGRES_PORT:-5432}"
DB_USER="${POSTGRES_USER}"
DB_PASSWORD="${POSTGRES_PASSWORD}"
export PGPASSWORD="$DB_PASSWORD"
# Create backup directory
mkdir -p "$BACKUP_DIR"
# Full backup
BACKUP_FILE="$BACKUP_DIR/full-$(date +%Y%m%d-%H%M%S).sql"
// ... (see reference guides for full implementation)

Best Practices
✅ DO
- Perform regular backup testing
- Use multiple backup locations
- Implement automated backups
- Document recovery procedures
- Test failover procedures regularly
- Monitor backup completion
- Use immutable backups
- Encrypt backups at rest and in transit
❌ DON'T
- Rely on a single backup location
- Ignore backup failures
- Store backups with production data
- Skip testing recovery procedures
- Over-compress backups beyond recovery speed needs
- Forget to verify backup integrity
- Store encryption keys with backups
- Assume backups are automatically working
