Another bad storage media are floppy disks. They are good for temporary storage and maybe transporting information, but not for permanent data storage. I've lost count of how many floppies I've tossed because they were bad. And I have talked to countless people who saved valuable data to a floppy only to find out when they needed to access it that the floppy was bad and the data inaccessible.
Another possible cause for data loss is power failure or spikes. It can result in loss of the document you are currently working on because you did not save it before the power failed and your PC shut down, or in loss of your entire hard drive because a power surge fried your motherboard and destroyed the file allocation table of your hard drive.
Also worth mentioning is data loss through virus attacks. There are plenty of nasty computer viruses out there that will delete files on an infected machine. That's why Virus Protection is just as important.
What data should you back up?
You might think that you probably don't really have anything worth backing up, nothing important, no big deal. Let's go through just a few items to jog your memory.

That would take a long time to accumulate those again. What about that to-do list you wrote? Or about that nice picture somebody e-mailed you and that you saved? How about that family history you collected over the years and put into a database?
Maybe you have a document for work, like a presentation or a spreadsheet that you created at home and don't have a copy on your work PC? Think about that saved game of your favorite game where it took you weeks or months to get to that level. These are just the most common examples, and I know that after thinking about it for a while you will realize that there is a lot of information you don't want to lose. That's why you should back up your
