How can you sincerely suggest remote backups if virtually none of them provide privacy provisions? If anything, people should be discouraged from using remote backups that are not encrypted at source.
Agreed that backing up only in transit can be sketchy. Most online backup services (including ours, www.Backblaze.com) encrypt your data on your client. Also, we provide an option to use a private key in which case not only is it encrypted, but only you have the key. Of course, if you forget it the data is completely unrecoverable.
