Object Tags

US3 supports using tags to classify objects in the storage space (Bucket), and users can set lifecycle rules for objects with the same tags. For information related to lifecycle, please visit Lifecycle. Currently, object tags support Vietnam and Brazil. If there is a need in other regions, please contact technical support.
