Repeat on the other server. When multiple users works with the same file that has no sync between hosts will cause a two different original files.

While looking at at way to monitor our DFS replication I stumbled upon the DFS Backlog By monitoring the DFS Backlog on each server we get a good and solid view to the state of our DFS replication. For the case I asume the build of HA shared storage between servers will do the job. We would also like that direcotry to synchronize with a Windows XP machine (laptop) via VPN and over the internet. Install the DFS Namespaces and DFS Replication roles on the two servers running Windows Server 2016 between which the replication will be configured. At this rate (1211 Transactions per hour), the initial replication would take an additional 8 days to complete. When reading Ned Pyle's article regarding DFS replication about getting the most out of pre-staging, He stated that an initial sync of 5.75 GB with no replicated data took 28 minutes. DFSR (Distributed File System) Replication it's a good solution to keep sync file servers when you have branches and must be share the same File Servers across the organization. In this video Grant will show you how the DFS Replication role service works, which can run stand-alone without the DFS namespace in place and allow you to keep folders on multiple servers in-sync with each other.

DFS-R is available in Microsoft Windows Server 2008 R2 and later and serves multiple purposes, from replicating the SYSVOL directory (replacing the older FRS) and as a replacement for the DFS Namespaces replication engine. Servers were configured to host our DFS Namespace and a shared folder was added to it. Distributed File System Replication (DFSR) is a replication engine that organizations can use to synchronize folders for servers on network connections that have a limited bandwidth. Now that we’ve configured our DFS namespace it’s time to enable DFS Replication and allow file transfer between servers. It is fine to simply set a replication between serverA and B to replicate the folder. This is an easy to understand topology, and relatively easy to troubleshoot, and it’s good if you have two main locations The problem actually only takes place between the two Server 2008 machines, so the Server 2003 R2 machine probably doesn't have anything to do with it. This also helps with conflict resolution scenarios where the same or multiple users update files on two servers in between replication, and one set of changes is lost.

By letting DFS Replication recover the database gracefully (as instructed in the 2213 event), the last writer will still win any conflicting versions of SYSVOL data. The folder is most likely shared so that users can access the folder, but this is not necessary. DFS (Distributed File System) Replication use a compression algorithm as remote differential compression (RDC) to replicate only the changes in file block instead of the entire file. DFSR will be used to sync the wwwroot folder between the two IIS servers in addition to one extra folder outside of the inetpub root folder which will hold the IIS Shared Configuration files.
