So, I bought a new ASUS laptop which I would like to play around with. I intend to wipe the HD in order to reinstall Win 7 and Ubuntu in dual boot - without the hidden ASUS partitions etc, which have caused enough problems on previous ASUS machines.
At the same time, I would like to have access to the original contents of the HD - as it came from ASUS. I am aware that ASUS offers its own backup and restore solutions, but I would prefer to do this manually.
To the question: I intend to use my Natty Live USB in order to copy the HD - all partitions - to an Ext4 formatted HD connected with USB. Ideally, I would like to keep the backup as a .tar.gz-file - in order to keep the USB HD useable for other backup purposes. What is the easiest way of doing this, using the Live USB?
