wubba,
Welcome to the forum and FOG in general. While you can use FOG like you intended. It’s not very efficient. FOG is really designed to be a business/enterprise imaging/deployment solution. So you would have 1 master image for desktops, and another for laptops, assuming you’re using XP. Or just having 1 Windows 7 image for everything. While you can make an image for every machine, it would require A LOT of hard drive space. Currently, our server has 7 images, plus bootable iso’s and i’m only using 56 GB of space on my drive. However, if you are looking at doing daily backup’s, I would recommend that you look at Clonezilla. It’s free and relatively easy to use. While FOG can do everything that you want it to, it might be a bit of a hassle and a lot of work to get it to work the way you want.
Please feel free to ask any more questions you may have, or if you have any concerns.
