The second component, DFS Replication (DFSR), performs replication of data between DFS nodes in the DFS Namespace.
With DFS Namespaces, you can make use of shared folders stored on computers throughout the organization to create a single logically structured namespace. This namespace appears to the user as a continuous and well-organized set of folders and subfolders even though the actual shared data may be in a variety of independently named shares on one or more computers in the organization...
