I use gotify for various services - it tells me when new stuff is added to jellyfin, it sends me notifications when uptime kuma detects something is down, if grafana monitoring thresholds are reached, after watchtower updates my docker containers, some homeassistant actions, info that some scripts finished and so on… It has a lots of uses.

I mean its 1 command to store your user crontab and 1 to restore it, so I would not over complicate it…

backup:

crontab -l -u root > /tmp/your-crontab-backup

and restore:

crontab /tmp/your-crontab-backup
