Windows secure file copy between servers

I have looked a bunch of questions on here somewhat related to what Im trying to do. Maybe windows has just not gotten on the security train yet.

Im not trying to use sftp, or WinSCP or SSH

Basically what i need to do is copy files from \server1\xxx\ to \server2\yyy

This will have to be done everyday.

I cannot install FTP on either of the servers.

Server 2012 r2 is the OS

However there are concerns about data in transit.

Is there a native way in windows to copy files securely?

Robocopy works fines for what I want however I dont see a way to secure the files from point A to point B

SMB is the protocol windows uses for sharing and it supports encryption for content in transit. It's always handy to include this term in any searches you do related to windows file shares.

SMB Encryption provides end-to-end encryption of SMB data and protects data from eavesdropping occurrences on untrusted networks.

The link also describes how to enable the functionality for either a single share or a whole server using AES CCM encryption either via the UI or Server Manager.
