And where is your backup???
I cannot say this enough times, raid is no backup. It only protects you from drive failure. It doesn't protect you from everything else like power surges, data corruption, accidental deletion and so on. If you want a backup, at least store the data on another hard disk. Preferably not in the same system.
		
		
	 
I agree with VIPER. Raid 1 is over rated for the most part except maybe for a drive hardware crash but will keep you up and running if thats the only problem.
When you have sofware issues well Ya Know......
Ok this is weird and I might be the only one that does this but what I do is keep a spare mirrored drive disconnected. 

 what tha
Every so often I will back up my whole system, os and all.
I Install the spare drive and reboot into bios. I set raid on save and reboot.
My system will come up with 2 crital arrays as the spare drive has already been mirrored before and has raid drivers from last rebuild. 
The computer thinks there are two arrays with a missing second drive each.
I delete the array on the channel that the spare is on. (os wont let me screw up and delete C drive fortunately because if there is a way to screw up something I'm an expert.) 
Delete the mbr on the spare and make it a free disk then I reboot which will rebuild. Afterwards I'll disconnect it and put it on the shelf that way if my installed drive crashes all I have to do is install the spare and I have a drive that will boot and run everything that was installed prior to the last rebuild.
Oh yea go back in bios and turn raid back off and the system boots normal.
I'll do this as I feel it's needed. It's nice to have a external drive dock.
Of course this isn't perfect as nothing is. I still have a backup drive for my data in the mean time.
sorry about getting off the subject of backup servers 

 this shouldn't even be in this thread
