It has it's dedicated place, and is my emergency backpack with everything to survive for a few days. It's simply connected via a sowed in keystone jack. It uses an embedded RPi powered by PoE (via said keystone jack) and auto syncs everything. It mostly only syncs PDF/A that I can use to view on a netbook, in case society collapses (instructions and manuals). Backpack has a small solar array and a 40mAh battery pack. Emergency equipment, knifes, axe, rope, fire kit and all of that. It's also the backpack I take on trips and hikes, to see its endurance. It's not meant as a backup your pictures kit, for that I have the four physical locations which are all in different parts of the country.

I think you know that I and everyone else knows that.
Wait till you learn about Wireguard.
Sure, but why not webUI vs VDI?
3-2-1-1-0 and you have 99.9999% covered. I replicate all backups between four physical locations, doesn't get more overkill than this. For personal use I even have a backpack with external HDD in it, that syncs the most important data every day.
Why do they need VDI to manage files? A simple web UI not enough?
Funny idea but I see no point in it?
Just setup VDI for him and give him a RPi 4, no need to use local hardware when he can work with his Windows 10 from anywhere.
Use XFS as file system and use --reflink when you copy the volumes, creates an instant CoW copy no matter how big the folder is. You can then move, copy or whatever that folder to anywhere, or use a VM and simply backup the VM.
