Can I Backup my WHS OS
From We Got Served Wiki
This question has been covered many times, in detail, on WGS (and probably elsewhere). The simple answer is you can't. WHS is a very 'dynamic' system and there is data in the OS partition that changes continually depending on where data is being stored on the other drives. This makes an OS backup totally impossible for anything except a simple single-drive system. Hence Microsoft has provided a very capable 'reinstall' facility that can restore the OS and rebuild the data pointers from the other drives. The amount of additional work required after a reinstall is not too great as it is limited to setting up the user accounts and any add-ins again.
