[64 bit] Backup default application

view story

http://ubuntuforums.org – I have a quick question about the "BackUp" application that comes with Ubuntu 12.04. I managed to set up my computer the way I like it. Now, I'd like to create a backup of my file system partition. I've research a few backup options (such as fsarchiver, partimage), but if I'm not mistaken, in order to be able to use fsarchiver I have to run it from a live cd. Therefore, I was wondering if I can use the Backup program instead. Maybe I could select the "/" and take the files and save them to usb flash drive. Would that work? Thanks much. (Hardware)
