What is the term for a type of S3 Object Lock that has a fixed period of time?

The term for a type of S3 Object Lock that has a fixed period of time is known as Retention Period. This feature allows you to set a specific duration during which an object cannot be deleted or overwritten, providing a safeguard for data retention compliance. During this retention period, the object is locked, ensuring its immutability until the specified time expires, after which it can be modified or deleted according to the established policies.

Other terms listed, such as Legal Hold, Governance Mode, and Compliance Mode, serve different functions within the realm of data protection and retention in AWS S3. Legal Hold does not have a set timeframe and is used to preserve objects indefinitely until explicitly removed. Governance Mode allows overriding deletions only by users with specific permissions, while Compliance Mode ensures stricter protection without the possibility of any action that would alter the locked object's state for the set duration. These distinctions clarify why Retention Period is specifically tied to a set timeframe for locking objects.
