Atlas Online Archive is designed to help you manage data storage costs by archiving infrequently accessed data to lower-cost storage. It integrates seamlessly with Atlas, allowing you to define custom rules based on data access patterns and retention requirements. The archived data is queryable, ensuring that it remains accessible without full restoration. This service is particularly useful for long-term data storage, compliance, and historical analysis, providing a scalable solution (though one that likely sacrifices some performance).
WARNING Online Archive is not a substitute for a primary backup solution because it is designed primarily for cost-effective storage of infrequently accessed data, not for data recovery purposes. Backups, on the other hand, are comprehensive snapshots of your data intended for recovery after data loss, corruption, or other catastrophic events. Therefore, it’s important to maintain a separate, robust backup strategy to ensure data integrity and availability.
