Pete Prodoehl 🍕<p>I forgot you can't just run a shell script with rsync calls via cron on macOS because of... security. I think my workaround will do though.</p><p>I write a shell script and then create an Automator application that calls the shell script. I then add a cron job to open the application. </p><p>I need to check if it runs when the screen is locked.

Dmitry Kudryavtsev<p>So I needed to run some periodic backup jobs, both for personal and professional needs. If were you ever tasked with such a request, you probably looked at cron. But cron has shortcoming: it does not survive power off events, it does not support any logs, and you can’t easily tell when, and if it was ran.</p><p>Meet systemd timers.
