That link isn't really a good comparison, because the version that I have has more than what is listed for True Image Lite. Actually, that is the first time I've seen the word Lite appended to TI, so I'm unclear as to what they mean? Even with the Plus Pack add-on, I never heard of it being referred to as anything other than just TI. Something that you might be able to tell me, I noted that the definition of a sector-by-sector backup is designed for using with unsupported OSs. I imagine that to do so, it would have to be run from a supported OS, or perhaps from a disc, but would it work to backup a Linux distro?
EDIT: I think that Lite version must be the one that is sometimes included with some hard drives, because it has far less features than the regular version.
