I'm looking for a way to synchronize a folder from one server to another.
I want one server to be a master server and all the other servers should receive the file(changes) from the master server quickly after they have been edited or added/deleted.
I've been looking in to DFS, but I believe this requires setting up a domain.
I've tried this in the past but the domain also changed all my user account logins, which is something I want to avoid on a server which has already been setup.
Another thing is that the servers are located in different locations of the world, so the traffic go's over WAN.
All servers use Windows Server 2012 R2.
What would be a good solution/implementation for this scenario?
