Backing up docker volumes

In today’s I-can’t-believe-I’m-doing-this-in-2024

I needed to re-build my webserver because it kept hard-freezing every week (another post for another day). Since I use a docker setup for this, my setup is pretty turnkey - I just needed to copy over my docker volumes from the old host to the new host.

That turned out to be a lot more annoying than what I wanted. See, this functionality hasn’t existed for a long time. You had to use some DIY StackOverflow scripts. Apparently, this functionality is now built into Docker Desktop, but A. I’m ssh’d into a server and B. Docker Desktop is the trojan horse where they extort people for licenses. In either case, I just have access to the docker daemon.

Running linux is an adventure. About a year ago, I switched from MacOS to Ubuntu (eww snaps), then Fedora (fine), then Manjaro (yeah that was a mistake) until finally landing on the final boss, Arch linux. Honestly, Arch is great. It does what I want, which is to spend an inordinate amount of time fixing things that used to work.

Backup on sugar, spice, &terminal? nice
