  • Stored in S3
  • Point-in-time recovery

Manual Backups ​

  • User-initiated backups
  • Retained until deleted
  • Can be copied across regions

Best Practices ​

  • Choose Right File System Type: Match to workload requirements
  • Use Multi-AZ for Production: High availability
  • Enable Encryption: For sensitive data
  • Implement Proper Backup Strategy: Automated backups
  • Monitor Performance: Use CloudWatch metrics
  • Right-Size File Systems: Match capacity to needs
  • Use Appropriate Deployment Type: Scratch vs Persistent for Lustre
  • Implement Access Controls: Security groups and permissions

Cost Optimization ​
