Does rsync use zlib compression, does it restore partition tables and bootloaders? I personally like rsync for syncing between servers but i recently stumbled upon clonezilla when I needed an install iso for my thin client project. It has a feature where it can turn a backup into a bootable iso so that was perfect. It can alsp restore vhd files to real hardware which was also something I needed. For most tasks I prefer rescuezilla since its a GUI for it. But the ability to spawn pxe servers and make isos sets the text based one apart.
