Hi, I have an old acer290 laptop that I use as a media server (mediatomb on Ubuntu 11.04) Worked beautifully with a number of remote players including a PS3. However ubuntu has ceased to support the 11.04 version. Before upgrading I'd like to make a clone (or near clone) of my system as a LIVE USB. With this, I can reinstall the whole system if I screw it up. Is this possible?, and if so how?. Suggestions appreciated.
