Yeah, but using an extra copy for failover requires that it be online 
*now*. Using an extra copy for redundancy only does not require that (and 
is much cheaper: how will you keep an extra online copy of the ATLAS 
detector's collected data? It's far too large to keep even *one* copy at 
any one site: keeping an extra online copy means doubling the size of an 
already large collaboration...)

Do you know how much data Google keeps. And they keep three copies not too. And in
Geographically separated locations. So the solution is essentially to make multiple copies.
Actually as Google has shown even two copies are not enough.
