A huge concern about using the cloud is that your data does not have the same Fourth Amendment protections that it would have if it were stored in a desk drawer or even on your desktop computer. Law enforcement agencies are requesting cloud-based data with increasing (and unsettling) frequency. And they can obtain access with relative ease, since everything you upload online—whether to a Web-based e-mail service, Google Drive, or Shutterfly—goes to a server that belongs to the cloud service provider, not to you.
