I majored in history and Spanish at Columbia, which is associated with at least two other people who have had notable computer-related careers/sidelines and eminent non computer-related careers: <https://en.wikipedia.org/wiki/Eben_Moglen> and <https://en.wikipedia.org/wiki/Edward_Mendelson>. (Not that I would put myself at their level.)

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.

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.
