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?

Just keep in mind "full backup" is not necessary and the resulting backups are large. You only need to back up user files (/home and /root) as well as any system files you edit. Personally when editing system files, I advise you make a backup (I save the original file as file.org), leave a comment as to you configuration (comments usually start with a # or a ;), and keep a copy of the file(s) in /root (such /root/etc/file). The only other exception would be servers, and in that case you would back up the server data (config files and /var/www for example). –  bodhi.zazen Dec 18 '13 at 17:58

You can also generate a list of all installed packages. See askubuntu.com/questions/9135/… –  bodhi.zazen Dec 18 '13 at 18:00
    
So what you are saying is if I just backup /home and /root I can get Ubuntu back to the way it is now even if something happens and Ubuntu gets messed up? –  spot9901 Dec 18 '13 at 18:00
    
See the link I just gave you. I use to do a "full back up" in the way you are asking, but the resulting backup files are large and more difficult to restore, IMO. –  bodhi.zazen Dec 18 '13 at 18:02

Use clonezilla on live CD/USB, its free and powerful. With this you'll be able to fully backup/restore disks/partitions including OS, userdata, etc..

Check : http://clonezilla.org/

Follow this to use : http://clonezilla.org/clonezilla-live.php#use

Clonezilla is the best, but every time you want to do a system image you have to boot off of the live CD. It's worth it to have the extra backups though =) –  John Dec 18 '13 at 17:58

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.

Would you happen to know what setting in Deja-dup will do a full backup because as I am looking at it I cannot find a way to do a full backup with Deja-dup. –  spot9901 Dec 18 '13 at 17:57
    
You have to go to backup folders and select the root directory. Make sure that you exclude your backup directory! If you need pictures let me know. –  John Dec 18 '13 at 17:59
