Auto Backup Feature? Where in the setting menu? How does this work?

Hello everyone, really like ZimaOS and trying to understand it more. Where can I set this “auto backup” feature that is advertised a lot? This was highlighted as one of the feature htat ZimaOS has and CasaOS doesn’t.
Is it in the settings? What is being backed up? Is it the entire system?

I also searched for that feature. As I understand it, this is only usuable, if you have a raid configured.
I’m running Zima OS from a zimablade with two ssds that are not in a raid but where I wanted to backup one ssd on the other. I do this now using duplicati which is a pity as duplicati throws in new problems.
