So my usb stick just died and I learned the hard way that my last backup was from 2017. I thought CA Backup does a backup everytime I did an appdata backup, but turns out I fckd up and had 'USB Backup Destination' empty. At some point before, USB backups to appdata/Community_Applications_USB_Backup were made though. Either I changed this manually or some plugin update introduced this new behaviour? Either way, I have recovered. Took a few h though.
I think this would be a perfect target for a new check, since the docker configs, which are deeply ingrained with the appdata directory, are stored on the stick. So I'd think most people would like this option set and warned if they forget.
