http://serverfault.com – Under windows system I'm used to create an image of HD with driveImageXML. What's the best approach to have an Image of the hard-drive containing the OS, with Ubuntu Server? I'd like to have a snapshot of the current configuration so If ever happens that the primary disk will fail I could simply restore this image on a new HD, unplug the broken one, plug the newly created.
