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.yamlapiVersion: v1kind: ConfigMapmetadata:  name: backup-script  namespace: databasesdata:  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
