I have been using Kopia to back up all of my laptops' home dirs to a raspberry pi for at least a couple years now. There is a CLI and a UI. The UI is somewhat funky and could benefit from an "easy mode" a la time machine, but it does work. I recently restored my home dir from it just the other day when migrating from one OS to another. My favorite thing about Kopia is that it performs incremental backups on tens of GB _much_ quicker than plan rsync can and is much more space-efficient to boot.
