As this is a non UC question you’d be better off to ask this on a more suitable forum. Newer the less I did Google DRF replication and second result was this that likely should be a good fit. https://docs.microsoft.com/en-us/windows-server/storage/dfs-replication/dfsr-overview
Sorry, but this is outside of my area of expertise and OT for the forum as it's a Cisco Unified Communication community. Neither of the other communities on this forum, like Security, Wireless or Routing and Switching would cover this either as it's a specific question that is around a functionality in a Microsoft product. You would be better off to search for a forum that have this target audience and ask your questions there.
