Cloud providers take care of your data, even in disaster. But you shouldn't leave the job solely to them
You've moved data to the cloud. Now it's time to talk about disaster
recovery -- how to build a resilient system that can recover from
catastrophic failure.
Amazon Web Services, for example, says its S3 service "is designed to
deliver flexibility, agility, geo-redundancy, and robust data
protection." To IT, that means the system is fault-tolerant, managing
the resiliency needs for you. ("Geo-redundancy" means that, if a center
goes down, another center in another part of the country or world will
pick up the load. You should never miss a beat.)
If AWS and other public cloud providers include a certain amount of
resiliency services, does that mean your data is safe? For the most
part, it is. Public cloud providers take great pains to see that data is
not lost -- ever.
