Do you trust Amazon S3 or Mosso Cloudfiles not to lose or corrupt your data?
bbuffone: S3, Mosso and other cloud providers are not an appropriate back up mechanism.  These are good for sharing files and a temporary storage system. The only legitimate backup is a physically stored disk. S3 doesn't provide versioning nor deletion protection.The problem is I hear about these new "Cloud" storage companies claiming backup, but when asked what do they do. They rely on Amazon to move the files into different data centers.  But anyone can delete a file or directory by accident and poof the files are gone forever.If the storage provider does have permanent physical storage in there backup plans, don't think your files are forever.
