Synchronizing two servers over the Internet?

Question

VPN

Hello everyone
There is a task, when I have never encountered such a thing, so I ask for the help of those who know.
There is a Win2016 Standart server with 1C and "file cleaning"
We decided to make another "CLONE" server.
The servers are located in different buildings with different providers.
What is required to synchronize two servers?

Answer 1

Synchronize the file dump via resilio/syncting and don't care where the server is.
protection, encryption, transmission confirmation and all that "out of the blue".
database synchronization is best done through the appropriate functions of the database management system.
Well, yes - it will be determined what function this "clone" has.

Answer 2

In Windows there is such a thing as DFS.
