[QUOTE="Zoolook, post: 1558639, member: 21101"] 99.999% of the time, you don't need a bootable backup, because even if your promary HDD is corrupted, holding CMD-R boots from a protected partition and allows a Time Machine backup. However, if your HDD is completely trashed, and you don't have a DVD Drive and/or physical media, you're stuck. I'd recommend a USB boot drive (see linked article below) rather than closing your entire drive. It might seem like a better idea to have the entire drive cloned, but you're potentially using hubdreds of GBs of space, just because you need something to boot from in the event you have a one in a million HDD failure.

Personally I think this adds complexity and expense that makes the cloning not worth it. You're better off with a SINGLE bootable USB drive that can restore any machine using a time machine backup.
