Why do I need to backup computer files?

It is a nagging question while some users still don't attach importance to files backup. They always think "data loss will never happen to me". But I have heard too many tragedies of people who lost all files because of system crashes, hard disk failure, power surge, or natural disaster, and get badly influenced. So, if you spend much time on your computer, a backup should be a must-have job during your computer experience.

Files backup can help you return things to normal when disaster strikes. By backing up files, you have a copy of your files. In this way, if your computer crashes or is attacked by a virus, you are still able to restore files from backup images to your computer. Unlike disk backup, file backup only backup the files which are of the most important to you or cannot easily be replaced, such as financial information, digital photos, music, videos or programs.

Backup Files to External Hard Drive

Should I save backup files to external hard drive?

There are many possible locations for backing up your computer files such as CD/DVD, external hard drive, NAS device, and online storage. But why backup files to an external hard drive? Here are some explanation in the following.

  • Separately from your computer. As mentioned above, computer-related issues, such as, system crashes, will result in data loss. So, you’d better choose a storage device outside a computer.

  • The price is affordable. Nowdays, external hard drive is very reliable and reasonably cheap nowadays. The price of CD/DVD is also acceptable, but its storage space is not big enough.

  • The device is portable and can take everywhere. This is very important for users who need to use backup files at different places, such as, home, office.

  • Save backup time. Compared with NAS or online storage, backing up your files to external hard drive does not require a good internet connection. So, the backup time will be less.
