This question already has an answer here:
I have been looking around but I cannot seem to find anything that will do a full system backup. Programs like deja dup let you pick which folders to backup but I want the entire Ubuntu OS and everything on it backed up onto an external hard drive. There are probably ways to do it in the terminal but I don't like to do those kind of things in the terminal and would rather have a GUI for this. Does anyone know of an application that can do FULL system backups and if so how?
