I am curious. A lot of people use the image backup that comes with Server 2008 and Server 2012. I understand that it works OK but.... what happens if you try and restore to dis-similar hardware? i.e. Different raid controller and drive configueation, CPU, etc......
Honestly, I never restored baremetal backup image on different hardware but on the similar hardware it went through all the times. In respect of different hardware you may face issues due to driver and all. However, please go through below articles which will give you more idea.
