@fristhost FOG Project and Clonezilla are close cousins in the terms of imaging. Each use similar cloning tools but go about it a bit differently. If you want a stand alone imaging tool use clonezilla, where you can clone to locally attached storage. If you want a network based imaging and management tool then use FOG.
If you want to get started with FOG there is a wiki pages to help with first steps:
And the user guide: https://wiki.fogproject.org/wiki/index.php/FOGUserGuide
Eventhough fog and clonezilla use similar cloning tool, you can not share captured images between the tools. If you want to deploy with FOG you need to capture the image with FOG. If you want to deploy with Clonezilla then you need to capture with Clonezilla. Both imaging tools have their advantages and disadvantages.
