Choosing where and how the iTunes folder appears in my computer

My computer crashed, taking my iTunes library with it. I've manually extracted all my purchased apps, contacts, and other important tid-bits that I could. Sadly my play-counts will be lost, but that's not too big a deal. Thankfully something like 95% of my music was on an external hard drive, so that's safe. So now I'm starting from scratch on this clean PC and I'd like to keep it organized.

When I first open iTunes he creates a folder in my primary Music folder, and fills it with metadata of some sort. This is, from what I understand, what I need to preserve somehow in the event that my computer crash. I think the "Library" is in here, and with that I can restore my iDevices if they were synced to that library. It's just that I don't want to have that folder in my music folder, I want to keep it somewhere on the desktop, in a folder marked "Software Fluff" so I can easily throw it onto a flash drive at the first sign of trouble. The weird thing is... when I move it or change it, and I exit iTunes and rejoin, a new iTunes folder is created in music. And he seems to ignore the old one that I moved.

Ah... I think I solved it with a Shift Start... lol. When asked what library to choose from, I picked the one in the Fluff folder, and he seems to have stuck to it. I reopened iTunes and it hasn't created a new one in Music.

Still... I wonder, if I leave it on my desktop there's always another chance that my hard-drive will fail. And if I leave it on a flash drive, there's always the chance that the flash fails too. Is there a way to keep a mirror of itself in two locations, simultaneously? So that as I add music to my collection and change the metadata, both of the iTunes folders are updated accordingly? Is this possible? Is this complicated to accomplish?
