Strictly speaking, any site that gives a flying f**k in a rolling
donut
about their availability should be doing this *anyhow*, even if
they aren't
worried about getting hacked.
Statistically, you're more likely to hear the sound of a disk
drive head going
into oxide-plow mode or the click-click-click of a dead servo
platter than you
are being hacked. And you're gonna want backups then.
And no, doing RAID isn't a cure-all. If there's a fire, all the
disks burn. If
there's a plumbing leak upstairs that spills zillions of gallons
of water
through your hardware, all the disks spark and short out. Plus,
I've seen
enough RAID controllers take a crap all over all the disks far too
many times
in my career.
