I use TechTool Pro 8's ProToGo to create a bootable image on a thumb drive and use it. It offers more configuration options than Drive Genius similar offering.
Hmm, another interesting approach that I was not aware of. As it is, I can either use the eDrive, or boot from the SuperDuper! backup, run TechTool Pro from there, and have it take care of my internal SSD. I actually have those same options with my MacBook Air while I am traveling, as I have a nice slim, external drive, and I always make a SuperDuper! backup of the stuff on my Air to a partition on that drive.
