Need to know how to back up windows 8.1 installation

Hi,

I have just installed windows 8.1 on Dual Core Laptop. Just wanted to know how can I create a backup of my Windows 8.1 installation so that in future if Windows crashes I can restore the installation+other s/w installed, like we do fresh install of Windows through USB boot.

Thanks
Nitin
