In follow Up - how simple and quick would it be to take a backup/snapshot made on failed hardware - and restore it to other hardware.

I am building a Windows 2012 R2 Essentials server and considering what benefit vSphere / EXSi would be.   I don't plan on loading multiple servers as this point.   However, having a second machine available to quickly transfer / relocate to could be possible.

Thank you for your time and input.
