Final answer:
Object tags can be replicated with Cross-Region Replication in Amazon S3 if the replication configuration includes the replication of object taggings.
Step-by-step explanation:
If you are using Cross-Region Replication (CRR) for Amazon S3, your object tags can indeed be replicated along with the objects themselves. However, this feature must be enabled in your replication configuration. When setting up CRR, you will find an option to replicate both the objects and their associated tags.
By default, replication copies objects from one S3 bucket to another while preserving the original object's metadata, ACL, and object tags.
To ensure that your object tags are replicated properly, make sure that the replication configuration includes the replication of object taggings. If you have this setting enabled, new object tags should be replicated along with any updates to existing tags.
It's important to note that any subsequent changes to an object's tags after the object has been replicated will only propagate to the destination bucket if the source bucket has versioning enabled and the replication rule includes change replication for object tags.
Make sure to enable the appropriate settings and verify that the source bucket has versioning enabled for ongoing tag changes to be replicated.
