DFS (Distributed File System) Replication is a file replication technology originally shipped with Microsoft's Windows Server 2003 R2 operating system.

DFSR allows creating multiple replicas of the content which thereby allow a level of resiliency. In the older versions of DFS (first introduced in Windows 2000 Server), the replication was handled by FRS (File Replication Service).

See the DFS tag for more info on DFS and DFSN (namespaces).
