Best way to Sync files from Windows server 2012 R2 to another Windows server 2012 R2 with only local admin privilege

Question

My IT dept give me 2 servers (Windows server 2012 R2), the first one have 4TB data, the 2nd one have an empty 5TB partition.
I have admin privilege on both servers.
I have to move all data from server-1 to server-2.
While moving (may take some days - idk) my team member still access to server-1 to edit/create new files.
I can't use DFS.
When I simply open Windows Explorer and do <c-c> <c-v> the server kicked me out and kill copy process after 15 minutes (I did try prevent this but anything works).
When I use Toucan to sync file, it got kicked out like Windows Explorer.
So, for you pro system admin, when you have to do my task with my privilege, what will you do?

Answer 1

I would suggest ROBOCOPY, more information here:

robocopy

Use /z so if the transfer is interrupted it can be resumed.

Then to fix the issue of 15 minutes log out, one suggestion would be to run this as a scheduled task. That way it runs as a background process and doesn't require an interactive user session to keep running. This page has a nice tutorial about setting that up and as per the article you can have it record its progress and status to a log file so you can see how it is progressing - as well as checking the scheduled task status. See:

As per the article, robocopy is a command line tool and perhaps not as intuative as gui sync tools out there. However it does one thing and does it well and it is from Microsoft, so doesn't require you to install any third party tools which may not be approved by your information security team.

Hope that helps.
