What Lutus talks about exists even when it's not for anyone else.
I have never been paid to write code, and my formal CS education is limited to AP Computer Science, and a one-credit Java class in college. I wrote 20 years ago a backup script implementing Mike Rubel's insight <http://www.mikerubel.org/computers/rsync_snapshots/> about using `rsync` and hard links to create snapshots backups. It's basically my own version of `rsnapshot`. I have deployed it across several of my machines. Every so often I fix a bug or add a feature. Do I need to do it given `rsnapshot`'s existence? No. Is it fun to work on it? Yes.
(I've over the years restored individual files/directories often enough from the resulting backups to have reasonable confidence in the script's effectiveness, but of course one never knows for certain until the day everything gets zapped.)
The 2 is I think because an earlier incarnation was by Art Mulder. There is also a Python implementation by apparently yet another person, which appears to be independently inspired by Mike Rubel’s writings.

I’ve worked somewhere that used Snapback, and that’s also from Mike Rubel’s writings.

There are also rsyncbackup, rsyncmachine, https://rsnapshot.org/, https://github.com/jonaslu/rsyncrotatingbackup (inspired by http://www.dbourget.com/software/remote-backup.pl), and several more with seemingly the same original inspiration.
