bit rot... What about good filesystems? Like ZFS which has checksums. Or maybe a zip with additional recovery data... I wonder if there is a ready-made solution that allows this to not require me scripting (and losing those scripts later or failing to run them because Bash was upgraded from 4 to 5 and Python from 3 to 4)

At least if you don't encrypt and those are jpeg it doesn't matter. I lost two discs at once with theWD debacle a few years back and couldn't recover anything as I encrypted the disk. Another drive that got bad, I easily recovered 90% of the files using foremost.

So no encryption on the local backup for me, only the emails dump by encrypting the zip that contains them. It's not perfect but that's the compromise I (think I) have to make. (The remote one is encrypted though)
