Most people have some or many documents on their computer that they just cannot afford to lose. That is why backing up your important files on a CD or DVD disc may be a good idea.
Today, our computers are very high tech, and a lot of them have some sort of data recovery tool installed. However, in some cases our computers do not work as they are supposed to and something goes wrong. This is why backing up data on CD or DVD discs could be a smart move. If your primary backup fails, or something happens to your computer, you have an external copy of the files.
CD's are very cheap and they can store up to 700 MB of data. This should be enough for regular files. If you need to backup lots of music and/or video files, you may want to consider using DVD's which regulary stores about 4.7 GB of data.
Both CD's and DVD's come in two formats CD-R and CD-RW (or DVD-R and DVD-RW). CD-R discs are cheaper, but they can only be used once. CD-RW (the RW stands for re-writable) discs can be used as many times as you wish.
Do some research before you buy your discs. Some computers may not be able to burn DVD's.
All you need to do now is to burn your selected files to the disc you have chosen and voila, your files are backed up, ready to be restored if anything goes wrong with your computer.
