Fair point, but it only takes 1 failure for a catastrophe. I suppose my question would be: is cloud-storage alone enough?

I've read differently... > Yes. On 12-21-12 Amazon notified us that 4 of our files (out of hundreds of millions) were lost due to a bug encountered while performing some sort of migration. 2 are gone forever and 2 are truncated forever. I've been using S3 for several years at Mixbook and Smule before that--this is the first loss I've experienced. http://www.quora.com/Has-Amazon-S3-ever-lost-data-permanently/answer/Scott-Bonds http://www.quora.com/Has-Amazon-S3-ever-lost-data-permanentl...
