retentionPolicy property
The bucket's retention policy.
The retention policy enforces a minimum retention time for all objects contained in the bucket, based on their creation time. Any attempt to overwrite or delete objects younger than the retention period will result in a PERMISSION_DENIED error. An unlocked retention policy can be modified or removed from the bucket via a storage.buckets.update operation. A locked retention policy cannot be removed or shortened in duration for the lifetime of the bucket. Attempting to remove or decrease period of a locked retention policy will result in a PERMISSION_DENIED error.
