Thanks for sharing this! Vorta seems to be exactly what I was looking for. I can't seem to get it up and running on Mac OS.
Edit: It looks like Vorta doesn't obey Mac OS's Dark Mode so it looks like the app doesn't launch.
There seem to be a lot of open source projects named after things in Star Trek.
Any plans to have a Windows client of Vorta? [Edit: Saw it now: "Windows is currently not supported by Borg, but this may change in the future."]
Vorta can run on Windows (it's in Qt), but Borg can't (for now). They are working on it though.[1]
You could probably run it today using the Windows 10 Linux subsystem, but it's not fully tested and will need some small fixes. Maybe later this year.
If anyone is interested in working on this platform, just post at [1]. It's probably very doable.
