COMPUTER DATA BACKUPS
WHAT IS BACKUPS?
Data backup involves the saving of your
data in two or more locations, so that if
something happens to your computer,
you still have your data reserved in
backup. This allows you to keep your
data even if you lose your computer.

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.
