Allow to set different throttling options for different networks

How are you using Duplicati now? Currently I can only set throttling options from anywhere. How would you like it to work? My backups are stored on a university computer. I would like to remove throttling limit when at university, but keep it at 300 Kbit/s at home to leave some bandwidth for other programs. Are there special considerations to this request? The big question is how to detect a specific network. Windows does detect it somehow in the Network and Sharing Center. Perhaps it's possible to query network name via some Windows API or use the same algorithm. I suspect they identify network by the router MAC address.

I am not sure how to ask the OS for it, but usually it works by detecting the MAC address of the gateway device. On a large network, like university, you may have several gateways, so you would need to register multiple times, but I guess a smart setup would be just throttling with the home MAC.

Somehow Windows manages to detect the network as same regardless of the access point that I use across the campus. In my case I would set a higher throttling limit only in the university network (because backup server is located in the same network), and smaller limit everywhere else.

Yes, but even with different access points, you are most likely still hitting the same gateway. On my university I hit the same gateway on both wired and wireless network.

As a starting point maybe this could be done in a binary fashion, meaning completely disallow backups to run when on specific networks or only allow backups when on specific networks. I like the MAC solution but more options are good as well like the suggestion in the WiFi issue below for reading SSID, another possibility would be to see if a specific machine is on the network (ping).

On Windows the sensible (to a user) binary way of doing it would be to respect the "metered network" flag.

Commenting here because #1705, which has a bounty and is specifically about the simple binary case, has been closed. Not sure why that is.
