I've never had to restore a backup (yet), but to me this is the best feature of Restic.
I used Duplicati for a while (I think it was Duplicati, not Duplicacy) and although the backups seemed to work, I kept reading about people having trouble during the restore process.
Restic is a slight chore to get set up with the environmental variables, figuring out which directories to "--ignore", etc... but man once it's set up it's just great.

I'm not sure I fully grasp what you want, but Restic is excellent. I use a cronjob to back up on a schedule. It's command line only. I think there's a tool to make it a GUI but I haven't tried it. They have a Docker image available but it's weird, you have to pass commands to it, it runs, then shuts down when it's done. I love Docker but that didn't quite work for me.
I use Backblaze B2 for storage, but any S3 will do. Restic supports all sorts of storage targets.
Credentials and things go in an .env file, or you can put everything into the command line every time.
When it's time to restore things, you can fricken mount the whole backup you want and browse the files, copy and paste what you need, etc. That part is really cool to me.
Backblaze is $5 or $6 USD per TB per month, so 500GB will be about $36USD a year.

Sometimes it's the only way to really figure out what's broken.

Nice work. I've replaced the wrong part before, but I learned a lot from it. Something was dripping on the exhaust manifold, so I replaced the heater core because it was in the right place, and coolant runs through it. It turned out to be the head gasket that needed replacing, so I got to do that, too. I'm in a different place now financially, and will never do either of those jobs myself ever again.

It's recommended to not begin boarding until it's finished, but one person moving around, gusts of wind, etc. don't bother it.

I've been trying to think through how it would determine longitude based on rotation of the earth and I agree, that's not really possible. I wonder what other tricks it uses to find the initial location.

This sounds pretty fancy.
Commercial aircraft get their location from multiple places including GPS, ground based facilities (VOR's), IRS, etc. IRS is what I'm used to calling it, but it's the same as INS, which is what this article is talking about.
It determines location by keeping track of rotation, acceleration, etc. It's often called "dead reckoning" because it just gives the best guess, and you don't know how accurate it is. There are multiple of these devices on each aircraft, and they compare their locations to the other sources and if one is drifting way further than the rest, it gets ignored. That's a very basic explanation because how it really works is way above my knowledge level.
It's very cool how these devices find their location, though. When you first boot the system up, it spends about 5 minutes measuring the rotation of the Earth. For this reason, you can't reset it when in motion. Based on what it feels it can determine your exact location on the surface of the earth.
