Still a bit strange to me that they started a whole new project rather than contribute patches or fork something else.
The only one I'm fairly familiar with is restic. It also compiles for the major OSes and has deduplication. For compression, I think there are patches available, but alternatively they could just have contributed one. That leaves tying the command-line interface to a few buttons in a GUI.
Edit: Kopia turns out to be from 2016. I guess the author didn't know of the others yet, or the others weren't as mature. This makes a lot more sense, somehow the .io domain and my first hearing of it only now made me expect this was written recently.
What I meant is that the author of Kopia could have done that and made their life a lot easier compared to starting all the way from scratch. But I posted that before realizing that Kopia is barely a year younger than Restic.
But of course it could also just be what u/poronski said in a sibling comment. His Noodly holiness knows I make a lot of software that already exists just because I enjoy the making and having it customized. In fact I think I also started... let me `stat` that directory... yup, in 2016 I started working on (and abandoned) my own implementation of encrypted backups. Also because online storage prices were through the roof (~40x the hardware cost price with servers and bandwidth included) and I thought I could do that cheaper.
