Rob Sobers writing about a statement Marco Arment made on his podcast about Dropbox:
>Marco’s response echoes my personal feelings about Dropbox and other public cloud services – treat Dropbox as though it’s nearly public. **Marco’s rule of thumb is that he doesn’t put anything in Dropbox that could potentially be harmful or embarrassing if it were leaked.**

Regular readers will know that I am paranoid about this kind of data breach. So my solution? Sensitive stuff goes inside an encrypted DMG inside of Dropbox. I am willing to trade a bit of security for the ease of use Dropbox offers.

Also remember that there is a Dropbox like solution that is encrypted on the user end, called: [SpiderOak](https://spideroak.com).

Or your can use [this tool to encrypt first](http://getsecretsync.com/ss/) (never tried it).
