My computer hard-disk is too heavy with data to accommodate more to it. Besides, putting the important in computer hard-disk is a bit risky, as it is vulnerable to virus attacks or bugs etc anytime particularly when it comes to internet hence a great deal of damage. Included in my data are educational videos on various subjects of studies, articles, blogs, essays, dictionaries, important software files, and highly important study material which I cannot afford to lose at any cost.
Now what I want to ask is "Can I upload this data to any secure website or something so I can download it online anytime and anywhere I want?" Please let me know if there are any sites where such huge amount of data can be accommodated?

Knowledgeable members are requested to help me in this regard. Thanks!
