Saw this article and recalled some of our threads here about RAID and Backup
and such.
This is a great example of how RAID Backup, of how data on RAID arrays
(even mirrored ones distributed world-wide) can be destroyed, and then your
only recourse is to have a good backup -- mag tape in this case.

Yes, despite all the ‘cloud this’ and ‘cloud that’ talk, when it comes down to
it, Google still backs up everything on tape.
And thank god they do.
The minions at Google, despite any other failings, remain Very Smart People.
They're not dumb enough to fall for the magical unicorn fart cloud hype; they
know that 'the cloud' is just a fancy file server with http:// access.
I do wonder how many metric tons of tape they buy every year, tho, and how many
of these they're buying:

(Current world champeen tape backup system...5 Tb per tape, uncompressed, you
can buy a 1 exabyte backup library from them...1 million terabytes. This is the
kind of thing that keeps Larry Ellison in Yachts and MIG's...)
