free online storage sites to backup your files

There are several advantages to storing your files online. Your files remain safer, you can access your files from anywhere, sharing huge sized files becomes easy, More privacy than your local PC and so on. Here let's see what are the best free online storage sites to backup your files

1. Google Drive

Google drive gives a free space of about 15 GB and that includes the space you are using in Gmail and google+. It's easy to access with your Gmail account and you can share files with anyone. Google drive supports images, videos, and other documents.
Supported Desktop platforms – Windows, Mac
Mobile & Tablet – For Android phones or tablets (Android 2.1+), For iPhone or iPad iOS 3.0+

Supported browsers – Chrome, Firefox, Safari, Internet explorer

 OneDrive     [Previously known as SkyDrive]

Microsoft has changed OneDrive. It is now 7 GB if you are a new subscriber to the service. If you are an old subscriber and had 25 GB of storage you get to keep your 25 GB.

I dropped OneDrive's ranking because of its reduced storage space, no encryption and the annoying OneDrive folder you have to use. It is built into Windows 8 and the service is expected to be around for a long time as it's provided by Microsoft.

OneDrive's storage size is 7 GB. This is not very large by today standards. OneDrive originally was 25 GB. A new user can't get 25 GB free anymore. If you have an old Hotmail account you may have 25 GB.

OneDrive is easy to use. Once installed just copy or move the files you want to backup to the special OneDrive folder. Only files in the OneDrive folder will be stored online. It may be less convenient for you but the advantage of this approach is that you know exactly which files are being stored online.

Spideroak 

Spideroak has end-to-end encryption. If you have documents you do not want anyone else to have the ability to see them, this is the service for you. The files are encrypted before they are sent to the Spideroak server. Since you own the encryption key, only you can open them. The downside for this service is that it only offers 2 GB of online storage.

The files Spideroak saves to the cloud can be stored in any place on you computer. A separate folder does not need to be created.

If you need to securely backup more than 2 GB of files, a free service is not for you. If you have more than 2 GB of files you want to keep and make sure no one can read them without your permission then I would suggest a paid service. Also, it automatically synchronizes files.

Dropbox 

It offers 2GB free storage to start while multiple paid options are also available. Dropbox offers file syncing between the PC / Mac / Linux and the cloud. Load the desktop client or upload through the web interface and begin adding folders to the Dropbox folder. Once in the folder, Dropbox syncs the file between the PC and the cloud and any other devices that you have enabled with Dropbox including mobile and tablets. Quick, light and in the background, Dropbox is a must try and is my preferred Online Backup Solution. One drawback to Dropbox is a folder named "Dropbox" which has to be created, then all the folders and files have to be moved to the "Dropbox" folder.

 iCloud

As you all know Apple has got more security than any others as they only support their devices to sync and share files. Only Apple users can make use of this. Once you sign up with iCloud you will get 5 GB of free storage for file backup and mail.
