The Data Replication Service (DRS) is provided with the Globus Toolkit 4.2.0 and first appeared in the GT 3.9.5 Beta release. The primary functionality of the component allows users to identify a set of desired files existing in their Grid environment, to make local replicas of those data files by transferring files from one or more source locations, and to register the new replicas in a Replica Location Service. The DRS conforms to the WS-RF specification and exposes a WS-Resource (called a "Replicator" resource) which represents the current state of the requested replication activity and allows users to query or subscribe to various Resource Properties in order to monitor the state of the resource. The DRS is built on the GT 4.2.0 Java WS Core and uses the Globus RLS to locate and register replicas and the Globus RFT to transfer files.
