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?

You can use Deja-dup for this. If you want to just backup all of your files, then you just have to set Deja-dup to backup your entire system. Make sure the Deja-dup does not backup your backup location or it will run into problems. If you are backing up to an external hard drive it will probably be mounted under /media/$USER.
I would recommend creating a system image because it saves all of your partitions and can be used to do a full system restore. It is common practice to do small backups of your home directory every day and then every week create a new system image. This way if your system gets breached, you can just restore a previous system configuration without worrying about your system getting screwed up.
