Backup Storage

Architecture

Implement robust backup strategies with S3:

  • S3 Standard for recent backups with frequent access
  • S3 Glacier for long-term retention
  • Cross-region replication for disaster recovery
  • Object Lock for compliance and ransomware protection

When to Use

This pattern is ideal when you need:

  • Database backup storage
  • Application state snapshots
  • Compliance-mandated data retention
  • Disaster recovery across regions
  • Ransomware protection with immutable backups

Common Integrations

  • AWS Backup for centralized management
  • RDS automated snapshots
  • DynamoDB point-in-time recovery
  • EC2 AMI storage

Considerations

  • Define retention policies before implementation
  • Test restore procedures regularly
  • Consider cross-account backups for isolation
  • Use Object Lock for compliance requirements
