Objective: My OS drive I want to be able, however imediately boot a drive which is identical to the dead drive, and has been 'slaved' to it for its duration (i.e. it has been incrementally backed up to), and that's it.

So in essence, my main issue here is the creation of bootable backups. I've spoken to mass consumer software company REBIT support, as well as read over different backup software forums, and it seems to me there is an understanding of this out there, but it's a bit hazy (judging by the wide range of opinions I've heard on it)...
1. People talk of some software copying the MBR while others don't. I'm not sure though if copying the MBR of a drive is all that's required to make it bootable. (Likely, I don't understand what truly makes an OS 'bootable')
2. If indeed, it is, then what I want is possible. I have an external drive running 'cloning' software (which is NOT an image, I understand, as an image is by definition a snapshot at a single instant in time). When my drive dies... I power off, swap my clone drive and boot up... the hardware AND software is none the wiser as to what just happened.... everything is back to normal.
It seems really simple, but I know there's something I'm missing here... something about the original drive, be it the MBR, meta data, etc.... makes it distinctly different from the 'cloned' drive... and I just can't figure out what...
It's bothering me because, IF the drives were, in theory, to be exactly (EXACTLY) the same, as the term 'clone' implies to me, the hardware/software should have absolutely no idea which drive is which... I should be able to freely interchange them (and boot, etc.) without even noticing...
I'm really interested in finding out IF that's possible, or perhaps more relevantly, if NOT - Why?
