Another one? Ten years ago I had trouble finding anything, then over time I learned of duplicity (2002?!¹), bup (2010), restic (2015), borg (2010)... all basically solving the same problem of encrypted incremental backups. The landing page doesn't mention why they made yet another solution. In the comments someone also mentions bvckup2. Is there an overview somewhere of all the different solutions? Any selling points…

It has a gui and works on Linux/Windows/MacOS. Also has both deduplication and compression.

Thanks!

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.

Any discussion about backup should always include a shout out to one of the most beautiful versions of this: bvckup2 About 10 years ago the founder just decided to start writing the most streamlined, beautiful pieces of software he could - obsession around NTFS nuances to improve performance and reduce overhead to an unbelievable degree. 10 years later, it's still him (and maybe a few other folks) and the software is…

I believe you about polish and performance, but that solution is neither open-source nor cross-platform (unless I failed to find it on the website).

To each their own.

For a lot of people it’s way more fun to make a new thing than to fork and patch someone else’s.

Nor free. The download button says a 2-week trial is included.

Which is okay, but licensing is enough of a hassle when restic etc. exist that I'm not going to bother with that for my systems. A design goal of restic (sorry I'm just familiar with that one, not affiliated with it) is also recoverability: if your repository gets horribly corrupted or you can't run the software easily anymore then the author wanted to be able to recover things still. One of the early talks (at a local CCC) explains how to decrypt things manually in a few minutes -- obviously he knows what he's doing and will be faster than me, but still. Having closed source software as an alternative to that... I dunno.

Looks interesting. I always liked the borg concept, but never actually used it for backups because it lacks windows support and a nice gui. Will give it a try.

Borg does have a GUI: https://vorta.borgbase.com/

Although it's subjective if you find it nice or not.

Yeah, I’m not complaining and it’s entirely fair to sell your work, but I’m always wary of relying on a closed-source (+ licensed) tool for things as critical as backups. I may be partial though, having interacted with the Borg author in-person a few times at Congress, which convinced me I could trust it to not shred my data.

Restic issues for adding GUI and compression are 7 years old. If if there was interest/"easy to do" for implementing them that would have been done.

I love the new tendency to use Polish (and other languages') names for programs!

The other day I heard someone use the word "żuk" referring to a bug, and I think it fits amazingly well.

Is it pronounced like Russian “Zhuk”?
