Which practice meets reliability needs by keeping synced data across different facilities?
Caching through a content delivery network
Transient storage
Cross-region backups that sync data
Locally attached storage volumes
Cross-region backups that sync data across more than one facility provide a reliable copy if one data center experiences a problem. This approach offers a protective layer that makes restoration more dependable. Transient storage does not maintain a persistent copy, locally attached storage volumes remain in a single area and may not address broader failures, and caching can help speed but does not store data long-term for recovery.
