If you're storing data in the cloud, then you/your software hopefully encrypted it first. You/your software did a verify (read after write). Your cloud provider has redundant storage at a separate location, so N+1 storage that's accessible. You paid your bill. You didn't otherwise let the security keys become vulnerable. Your internal security is up to snuff. And no one had an errant backhoe near your circuit to the cloud host. Your data is safe, just as it would be in your data center.
