Thanks for the inputs, guys.
Actually, because I'm using Windows OS, I prefer making an image for my C drive to reistalling the OS (it costs me a lot of time to upgrade patches/ hotfixes, blah ... blah... again).
Right here, I have 2 questions for you.
1/ My home server is sitting on Windows server 2012 essentials, not WHS 2011. Can I make an image of my C drive with server backup option? I've never done it before.
2/ Where should I keep the image when I do a backup for my C drive? As I said before, I don't have any extra disk to hold the image. Is that a good idea to keep the image in one of my data drives? If possible, how can I restore it once C drive cannot boot up?
Once again, thank you.
