Watchdog for restic backup that are automatic triggered via an interval

TLDR: Bash script that emails you if your restic backup interval is overdue.

How does it work?

The script monitors the backend of a restic backup. The bash script is executed via cronjob or a systemd-timer periodically. The user sets an interval for each restic repo (e.g. your laptop-backup). This is the same interval as the one that triggers the automatic backup from your device. If your automatic backup failed (e.g. no Internet), there will be no changes in den repo. The script will notice that and emails you.
