Flash Archive for Solaris 10

Solaris 10 has an awesome utility called Flash Archive. It is a cloning program that allows me to create either full or differential images of systems. I can do a complete backup of my system with it. I use "flarcreate" command and put my image on a mounted NFS share. Later, when I need to reclone, I boot from Solaris Express install CD and point to the NFS share. Here is Sun's manual:
