I'm a noob to linux, been using ubuntu for some years but in no way an expert. Usually on my freetime i try stuff and occasionally break the os and then simply reinstall and try again :)
however now I use my ubuntu labtop at work and I'm terrified that I will do something stupid and mess it up.
What I want to do is create a full backup of my current installation into an external hard drive and be able to boot up from it so in the worst case scenario that the entire os shuts down and I am welcomed to a black screen. Then I could simply boot from my backup harddrive and be back from where I left off.
Is there a good tool for this? preferably one with a GUI? I used deja drop but I'm pretty sure that only creates backups that I can go back to from within a working installation. Not a backup I can access if the whole system breaks down. I've also heard about clonezilla but have not managed to find a gui for it.
