Which object store configuration prevents data loss on server crashes?

The persistent object store configuration is designed to prevent data loss in the event of server crashes by ensuring that data is saved to a durable storage medium. Unlike other configurations, which may only hold data temporarily or in memory, the persistent object store writes data to physical disk storage, allowing for recovery of that data even if the server fails. This characteristic makes it ideal for use cases where data integrity is crucial and the risk of loss during outages must be minimized.

In contrast, non-persistent and transient object stores typically retain data only in memory or in volatile storage, and they do not guarantee data retention through server restarts or crashes. A local object store can also imply local-only storage solutions that don't inherently provide persistence guarantees against failures depending on how it's configured. Thus, opting for a persistent object store is essential for applications that require reliability and the ability to restore data following unexpected system failures.
