I try to be in the habit of making a full image onto a demonstrably working spare card every couple weeks.
That’s a whole lot of writing to an sd card, wearing it out. It may fail by the time you want to read it. You also destroy each previous backup by creating a new one.
Each of my rpis backup to my main server nightly using dd via ssh. The server then keeps historical backups of those .img files via Borg so I can pull any version from any day of the last year or so.










Well, that last one he’s already not doing himself I’d bet.
Takes a lot of energy to reach your own toes, he fall asleep halfway there.
