Why do I need to backup computer files?

It is a nagging question while some users still don't attach importance to file 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 failures, power surges, or natural disasters, and got 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 that are of most important to you or cannot easily be replaced, such as financial information, digital photos, music, videos, or programs.

Should I save backup files to an 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 explanations in the following.

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

  • The price is affordable. Nowadays, external hard drives are very reliable and reasonably cheap. The cost of a CD/DVD is also acceptable, but its storage space is not big enough.

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

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

How to backup files to an external hard drive (3 ways)

Speaking of how to back up all files on external hard drives in Windows 11, 10, 8.1, 8, 7, and older versions, you may think about using Windows built-in tools, such as Backup and Restore, and File History. I’ll introduce you how to use them later. However, in the first place, I’ll introduce the easiest way first.

Not a single backup only backup files at a certain time point. To include all the changes made later, you need to create a schedule backup to protect your files continuously.

Method 1: Backup all files to external hard drive with free backup software (Recommend)

AOMEI Backupper Standard is free backup software that allows you to backup files to an external hard drive in Windows 11, 10, 8.1, 8, 7, Vista, and XP. It also supports back up system, disk, and partition if you need it. You can enjoy the following advantages of this software:

Backup files automatically: You do not want to lose any data due to unexpected disasters or forgetting to backup files. You can enable daily backup, weekly backup, and monthly backup to backup them automatically at a regular time.
Backup only changed files instead of full copy: Your backup disk may be fulfilled soon due to accumulated backups if you back up all files every time. To slow down this issue, you can choose only backup changed files with incremental backup.
Other useful features: If you are worried that your computer may fail, you can choose to create a boootable USB or CD/DVD in advance.

Then, download this software and install it on your computer. Please connect your external hard drive to the computer and make sure it can be accessible.

Method 3: Backup files to external hard drives with Backup and Restore
