Why Do You Need to Backup Your Data?

If you know that corruption happens, hard drives will fail, motherboards will short out, and mistakes will erase data, then backup your data is needed. Backing up your data should be at the top of your computer maintenance list. Without data backup, you are running the risk of losing your data.

Data loss can happen in two ways.

1. Physical failure of the hard drive where the data is stored on. You may have everything saved on your PCs hard drive, but it will not live forever. It might happen gradually; by more and more bad clusters accumulating until most of the drive is unusable, or it might dies without warning. Another possible cause for this is power failure. You may loss of your entire hard drive because a power surge fried your motherboard and destroyed the file allocation table of your hard drive.

2. 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?

Do you want to lose the e-mail addresses from all your friends? 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. So, backup your data is very important for you.
