I know there a few tech guys on here much more knowledgeable than me so here's what I'm looking to do, any help appreciated:
I want to have a perfect backup of my current hard drive on another hard drive inside my computer so that if my main drive dies then I have a perfect backup that just needs swapping over or reconfigured via bios to be the boot drive.
I've heard that this can be done - something to do with RAID setup, connecting them in parallel I believe?
Can someone explain exactly how to do this and how much it's going to cost me?
The advantages and disadvantages would be great also.
Thanks for any help,
