ClonezillaClonezilla is one of my favorite cloning tools. It's more like a bootable Linux distribution that can do bit-by-bit copying, and it supports a ton of file systems. There's an unattended mode and multicast support built in. Clonezilla might be the single most powerful disk copy tool available that doesn't have a price tag.
