> Do you trust yourself to store things safely without data loss (even in the face of theft, house fires and natural disasters) more than the multi-level redundancy employed in the cloud?
No: I encrypt my data locally, using protocols I believe/hope are strong enough, and then upload the encrypted data to cloud storage providing multi-level redundancy.
Right now, this is a somewhat painful process, since Google (quite deliberately, I think — 'Don't Be Evil' is now but a fading memory) choose not to facilitate it, but there's no reason why it shouldn't be as simple and straightforward as using the cloud without encryption.
Key management isn't really that difficult: have one master key, stored encrypted under the highest-strength passphrase one can remember, accessible using trusted client software (i.e. not something running in a browser). Done.
