Autonomous Database provides cloning where you can choose to create a full clone of the active instance, create a metadata clone, or create a refreshable clone. With a refreshable clone the system creates a clone that can be easily updated with changes from the source database.

For details on creating a clone that is a full clone or a metadata clone, see Cloning and Moving an Autonomous Database.
