Backup Planning
- AWS Backup centralizes backup plans across supported AWS services.
- Backup vaults store recovery points and can use vault lock for stronger retention controls.
- Lifecycle rules transition backups to cold storage when supported.
- Cross-account and cross-Region backup copies support resilience and compliance needs.
Recovery Targets
- RPO defines acceptable data loss; RTO defines acceptable time to restore service.
- Automated RDS backups support point-in-time recovery within the retention window.
- Manual snapshots remain until deleted and are useful for long-term retention.
- Restore testing validates that backups meet the business target, not just that backups exist.
Exam Cues
- Need central policy across accounts: AWS Backup with Organizations support.
- Need immutable retention: evaluate vault lock or S3 Object Lock depending on the data.
- Need fast database HA: Multi-AZ is usually better than restoring from backup.
- Need cross-Region recovery: copy snapshots or backups to the recovery Region.
