I want to use timeshift to make backups. But I only see it make backup for /usr, /var. So I want to know whether it will make backup for /boot, /etc,...
If I broke the files under /etc, will the timeshift be able to help me fix it?
Also I remember there was a time I use timeshift to restore files, and when I reboot I found there are two "grub", not knowing why.
Can someone explain my Questions? I'm a new hand Ubuntu user.
