You’re right. Syncthing isn’t a backup tool per se and the devs even tell you that in the FAQ. But forgive me if I did preach about it anyway, because you can enable file versioning (keep old and deleted files on each host) which kind of makes it backup incase something bad happens? Anyway it is my set and forget solution for Linux, Android and Windows. If you could recommend me a alternative that ticks these boxes I’d appreciate that. :)
