My company just set my laptop up with Backblaze, and the backups are killing my crappy rural DSL connection when I bring the machine home. Are there utilities that can block specific applications from accessing the Internet on specific Wi-Fi networks?

I've seen recommendations here for apps like Little Snitch or Radio Silence that can control Internet access on a per-app basis, but they don't seem to say anything about specific Wi-Fi networks. Can Automator control these apps when connecting/disconnecting from a specific Wi-Fi network?


Try TripMode, https://www.tripmode.ch

It is specific-network-aware, so you can activate it when you are on the constrained network, and after that it will remember, and auto-activate itself there.

  • Thanks! I'm giving that a try. Not seeing any per-network settings in TripWire though. Are you saying TripMode will turn itself on or off when I change networks depending on what I had it doing on that network previously? Apr 17 '19 at 16:50
  • Yup, as the documentation says. Apr 18 '19 at 1:59

I was going to install a version of Little Snitch to test, but it requires me to restart my computer and I don't want to do that... Anyway:

I'm pretty sure you can create a rule in Little Snitch to block Backblaze and then just toggle it on when you leave work and off when you get back.

They have a free trial, so it is pretty trivial to test if you like the setup.

  • Thanks for the suggestion. I'd rather configure an automated setup than have to turn it on and off every day. Apr 17 '19 at 16:54

I'd also consider giving IceFloor a try too. It's FOSS. It was discussed previously on this site here: Which free alternatives to Little Snitch can I use to block internet traffic per applications?.
