Hmmm..... Isn't it simpler and cheaper to just keep a backup system?

Dual- everything means a more complex system and hence more chances of
something to go wrong (be that due to misconfiguration).

Before jumping up and throwing hardware at the problem, think what the
problem actually is. For instance, why a RAID? What are the important
data we wish to keep?

Can you afford loosing a couple of hours of records in case of such a
disaster (from your last copy).

Oh, and something in the news from yesterday:
