installation snapshot and restore

[Joao Ferreira gmail]

Hello,

is there a recommended way to snapshot a fresh ubuntu (9.10 in my case)
installation and restore it afterwards.

I'm thinking something like storing an image file on some alternate
media, and when I want to restore, maybe I'dd boot from some live CD and
restore the image to the partition.

(I have ubuntu installed on /dev/sda6 (with grub also on /dev/sda6). I
have another linux on /dev/sda4 and another grub in the MBR that
chainloads the ubuntu grub).

thanks a lot

Joao
