Amazon uses ECC [1] (search ecc) MS Azure uses ECC [2] Rackspace uses ECC [3] While compute servers aren't backed up this is by design (use storage). Storage is indeed backed up and replicated. Also most assuredly there are extensive disaster recovery plans. The cloud isn't for everyone, but FUD doesn't help.

While compute servers aren't backed up this is by design (use storage). Storage is indeed backed up and replicated. And yet, you are referring to pages about redundancy, not backup. Redundancy helps when a disk, server, or perhaps even data center fails. Backups help when your cloud storage provider makes an error and removes your data from redundant storage. There have been enough incidents to show that cloud computing alone cannot be trusted [1]. Unfortunately, most cloud services are data silos, so you couldn't even backup data if you wanted to. And then we haven't talked yet about data leaks. Some larger incident than last year's iCloud leak will probably happen sometime. Hopefully then people will realize that client-side encryption is important. [1] https://news.ycombinator.com/item?id=8440985 https://news.ycombinator.com/item?id=8440985

  For one the iCloud leaks had not one thing to do with cloud computing. Nor did the dropbox one you linked. Those were application level problems, and could well have occurred with on premises based storage (obviously with a public interface for an icloud issue). Let me assure you that bad synch algorithms have caused data loss before the cloud. Applications can fail to backup or record things. Also I provided only links to ECC proof.

But the difference is that if you manager your own storage, you know what backups are made, etc. Dropbox claims that backups are made, but these users lost data regardless.
