server allows WORM for specific objects or by configuring a bucket with default object lock configuration that applies default retention mode and retention duration to all objects. This makes objects in the bucket immutable i.e. delete of the version are not allowed until an expiry specified in the bucket's object lock configuration or object retention.

Object locking requires locking to be enabled on a bucket at the time of bucket creation refer to `mc mb --with-lock`, object locking enables...
