Save your computer stuff today and everyday

Last year, I had a computer that crashed. I was so mad. It just locked up and I could not get it work at all. I am still not sure why it quit working but the hard drive was dead and the only way to get it working again was to wipe the memory clean. I lost all the stuff that I had on my computer, all the emails, pictures and other important stuff. That will not happen to me again because now I have online backup. I will never again lose everything on my computer.
