You can make this work using ext and Timeshift rsync. I have also opted to exclude /var/lib/flatpak/
because it’s quite large. With that, my 5 snapshots currently take up about 34 GB.
However, I would recommend backing up your deb applications/packages (typically installed under/usr
), as those can be critical for your system.
The driver should already be installed but there seems to be an issue with
brltty
registering the corresponding USB ID when they shouldn’t. You can probably fix it by following this guide: https://koen.vervloesem.eu/blog/how-to-stop-brltty-from-claiming-your-usb-uart-interface-on-linux/ (or this one: https://unix.stackexchange.com/a/670637)Edit: Perhaps this has since been fixed in Mint 21 / Ubuntu 22.04.
