free online hard disk servies?

From last three months I am using this feature of online hard disk. There are lots of online websites that are present which provide the online storing of the data. You have to just visit websites like the idrive, datad. You have to register over there after that you will be able to store data there in your account that they provide to you. You will have to first upload the data that you want to store on the online hard drive. One more thing that I want to clear you that you need very fast internet for the accessing of those data and uploading of those data over there. You can also upload the data that are very important for you, they will make a data backup by the help of which you can access those data any time you want.
