<i>&gt; demonstrate that ... on a number of cloud platforms ... that their rates of data loss are significantly higher than your &quot;home spun&quot; storage</i><p>You seem to be missing the point.<p>People are not saying &quot;don&#x27;t use cloud storage <i>at all</i>&quot;<p>They are saying &quot;don&#x27;t use cloud storage <i>exclusively</i>&quot;<p>You might trust that your cloud providers will never be hacked, that your individual account on them will never be hacked, that they will never suffer a catastrophic failure, that they will never go out of business, that they will never be fully or intermittently down at the moment you need to retrieve some data, and so on and so forth, based on their claims and documentation, or that you won&#x27;t cock up at some point and cause data loss in your account, but I prefer to have my own copy (or copies) as well as the ones that are &quot;in the cloud&quot;. For truly essential data at least one of those copies is both offline and offsite.
