In PCLinuxOS I use their MyLiveCD (command line) to make a system backup iso which I can put on a usb stick with their LiveUSBCreator and essentially remaster my installation on another computer, and it works very well.
Does Kubuntu have something like MyLiveCD? I see where Kubuntu has LiveUSBCreator, but I don't see any MyLiveCD to make the system iso file.
1 yr PCLinuxOS user trying Kubuntu on 2nd laptop, very impressed with it, may move to Kubuntu entirely.
As a system backup, I use CloneZilla which I use to back up everything except /home/ and BackInTime for data back-up (my /home/). I've tested system restores already a few times after I've messed up my system and data restores after I've deleted a file I didn't want to delete... ;-)
You, on the other hand, might want to use CloneZilla to back up everything, depending on your needs!
An alternative for you might be TimeShift which allows you to back up entire systems with differential back-ups keeping each differential back-up completely restoreable... (I've read all documentation of all back-up programs around and this one will be next on my list to to test whether it's good enough to replace my CloneZilla/BackInTime combo)
Of course it has a live CD. How did you install it? The normal way is to download an iso image and burn a CD/DVD of it or take it onto an USB stick. But to access your data, you can use any other Linux-based live system, too.
