content: "locally encrypt your data before uploading it" This nugget of wisdom does not get the attention deserved.    You can only trust that which you physically control.  Period.  Every MBA that sold "Cloud-sourcing" to the bosses as a means of reducing IT staffing costs should be fired as a corporate traitor.  Every single item or service placed onto the cloud should be classified strictly in one of only two categories -- 1) Free and Open for anyone to use anywhere and any time without your knowledge or permission required, or 2) Encrypted and secured before uploading and backed up elsewhere for redundancy to guard against unexpected and uncontrollable loss. "Cloud" anything is inherently insecure and can never be otherwise as you are entrusting strangers in an unknown location with your data.
