Crontab to just auto reboot daily is probably better - if your PC becomes unresponsive I doubt it would be able to execute another script on top of everything. Ideally though, you’d do some log diving and figure out the cause.

Frigate + reolink is a great combo.

You might try adding :rw after each of your volume paths, like this:

volumes:
      - /path/to/appdata/config:/config:rw

My honest suggestion would be to ditch Duplicati for Duplicacy. Duplicacy is one time payment, but it’s much more polished than Duplicati. I actually had major issues with recovering files from Duplicati; sometimes it would work and sometimes it wouldn’t. Not ideal for something as critical as backup software.

Duplicacy is a great solution, well worth the cheap price. It can do changes only over many different protocols.

I also would recommend setting up something like Uptime-Kuma on it, and also an instance of it home. This way you have an external monitor for your own home network, but also a monitor for your backups! Both Duplicacy and Uptime-Kuma can run on docker.

Regardless of service, if you don’t test your backups, you have none.

I hate to ask the scary question, but have you tried to restore your backups before? I used Duplicati and discovered that none of my backups were usable and ended up switching to Duplicacy.
