(e.g. Intel PAT and Acronis)
For example i create an image of a specific computer (Gold PC) then be able to deploy (which is already implemented)
I update/install new application/made changes to the (Gold PC) and if I create an image I have the option to build a increment Image or Package(based on the changes that has been done to the (Gold PC) and this can be used to deploy to other machines.
It saves time reimaging and deploying.
