What's great about online storage and back-up sites is that you don't have to worry so much about your files getting lost. Computers get damaged, no matter how up to date or awesome the specs are, chances are they will give up on you in a matter of years. The worst part is that you never know when, which is why it's always a must to keep a back up of your files. Backing your files in an external drive is also a good option, however, it can get lost. The best choice is always to upload your files online. So when the time comes that you need them, you'll have a secure data recovery every single time. Online storage and back-up sites are very reliable and they keep your files safe and secure for as long as you want.
