[Lilug] LiveCD disk backup software

[Will]

So, I'm looking to back up a 1TB drive to a computer somewhere on my
network. I don't have too many files on the device itself, but I want to
back up the partition tables still so I can just restore the device back to
before I backed it up. I don't have another 1TB drive, so I was wondering
if there was any LiveCDs that would be able to compress it, or are just
efficient.

Has anyone had success with any particular liveCD in the past?
