Backup data

Why should you back up?

Data loss can happen in many ways. One of the most common causes is physical failure of the media the data is stored on. You probably have everything saved on your PCs hard drive .That hard drive will not live forever .

normally hard drives will live for years without incident But eventually they will die. It might happen gradually by more and more bad clusters accumulating until most of the drive is unusable Or it might happen suddenly, the hard drive just dies without warning.

Another possible cause for data loss is power failure. 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

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.


There are many ways to backup data on your computer - the least effective of which (for obvious reasons) is having the only backup location on your actual hard drive. Instead, use external hardware such as a disk, CD, zip drive, or memory stick.

In general, the safest choice is to back up your critical data to an external media . Some popular options are External Hard Drive, CDs, USB Flash drives The option you use will depend on the amount of data you want to back up.
