Cloud storage: How to Sync Your Own Data Securely and Privately

I love cloud storage and syncing, but I can't exactly ignore its faults. If you need a lots of storage, you have to pay an annual free. It's almost always slower than a local connection. And wordt of all, it has some very serious security problems. NSA whistleblower Edward Snowden described Dropbox as a "targeted, wannabe PRISM partner" and "very hostile to privacy."

To help you get around these problems, I'm going to offer ways around the cloud. I'll also discuss making the cloud more secure.

An external hard drive: 

This is the obvious choice, of course. But there are two approaches to doing it.

First, you can use a program such as Allway Sync to synchronize your files between  the internal and external drives. When you move from one location to another location, you plug in the external drive, run allway sync and do the update. When you are ready to move to the another system, you sync them again. The free version is sufficient, but only available for personal use. The pro version is properly priced- about $50 for two systems.

Network-attached storage (NAS):

Basically, This is a device containing two or more hard drives, attached to your router so that you can open any file on any computer on your local network.
How does it will help you when you miles away from your router? Today NAS system, such as the WD my cloud mirror, can provide a private cloud storage. Only you can access the files on your NAS via an encrypted internet connection. Nobody will access your saved files.

Encrypt Locally: 

You don't know with whom dropbox, Microsoft and Google will share your files. But if the files are encrypted before you upload them, they can't be share much. 

There are many ways to do this. According to my preference: I store my sensitive files data in a VaraCrypt container.

Use a secure cloud service:

 Many companies of big storage don't protect your privacy, but some small ones do. Snowden recommends spider oak, which encrypts and decrypts the files data on your PC, with a key that only you can access. Spider Oak would not share your files data because they can't open them. According to the Snowden That's the only way to prove the customers that they can be trusted with information.
