Hi, I have the same problem, update-grub adds a backup partition to
the grub.cfg.
Even if the os-prober gets a blacklisting option, I think the grub
config updater should also be able to blacklist devices that the user
explicitly don't want to be added.
I've made a small patch for the 30_os-prober script that allows you to
blacklist devices by adding an option in /etc/default/grub
As an example, to blacklist sda3 and sda1:
GRUB_DEV_BLACK_LIST="/dev/sda3 /dev/sda1"
Hope it can be useful.
