Retention Policies and Object Lifecycles
Object lifecycles are well understood in terms of storage classes - standard, nearline, coldline, archive.
- You can change the storage class of an existing object either by rewriting the object or by using Object Lifecycle Management.
However, retention period is different. And it can be overridden by a storage admin.
The only way to prevent someone from overriding a retention period is to lock the entire bucket.
