Backup remote windows machine to my local server

Support and Help
1

Hi, I want to back up a remote windows machine in another country to my local server running Ubuntu.
I want to do it over a vpn, with only acess to the servers ip address and nothing else like my local outside Internet.
I also have a Dynamic DNS.

So, how do I get that too work?

Do you want the full OS backing up or just some files?
Is the Windows machine a VM? Do you want to back up at that level?
Details please

Full OS. It’s not a VM.

Could use Veeam Community edition then install the Veeam agent on Windows. It uses VSS to do a full OS backup as you need.
Other options exist. Just my opinion
