Why to Encrypt Despite of Powerful Security Schemes by Cloud Services

Although Dropbox does employ powerful encryption methods, the hidden flaw in them shocked its users some time ago when it temporarily allowed anybody to access a Dropbox account, thus, bypassing the security scheme. So, it was this incidence that made the Dropbox users proactive to encrypt their own files, thus, providing double encryption (one of the cloud service and other of the user) for ensuring an impassable security scheme.

Apart from that, there are users who do use an encrypted Dropbox volume such as TrueCrypt. However, sadly, relying on such a volume somewhat beats the concept of using a remote cloud drive that updates and stores your files incessantly. For example, if you are using a big encryption volume, know that the cloud service will upload it only if you unmount the volume. Further, if you are working on the volume, you might lose the continual backup advantage. So, what’s the solution?
