Backup Computer to External in Windows 10/8/7

Updated on Apr 23, 2019 by Tracy King to Backup Utility

Are you looking for a way to backup your PC, laptop in Windows 10 to keep your system, programs and files safe? Regularly backup computer to an external drive is a good idea. It is really not so hard as you have expected. Here we'll show you, step by step, how to create a backup image of your PC to an external hard drive in Windows 10/8/7.

Why do you need to back up the computer to an external drive or a flash drive

Have you ever accidentally delete a file or lose a bunch of your data after a system crash, disk formatting, virus attack or some other accidents? Usually, people never think data loss will happen to them until it actually does. To avoid such an unexpected disaster, it is important for you to regularly make a copy of your computer. It allows you to backup system, applications, settings and personal data such as photos, videos, music files, etc, and then you can rebuild your system and restore your data when you need. 

Then a problem comes out. Where will you backup your computer to, an online file-hosting service, internal disk or external hard drive? Backup computer to an online file-hosting service requires a broadband connection that has enough upstream bandwidth. But as a matter of fact, many people don't have sufficient upstream bandwidth. Backup computer to internal disk will obviously take up some space and even slow down the computer. And the backup file might be corrupted or get lost and not available when something bad happens to the computer. For all of these reasons, we think the best choice is to back up the computer to the external drive. 

Backup PC to external hard drive or flash drive using Windows 10 built-in backup feature

1. Connect your external hard drive which has enough free space on your computer.

2. Go to the Start Menu, type "backup" in the search box, and hit Backup and Restore.

3. Click the "Set Up Backup" button. Pick the external drive you plugged in and hit Next. Windows' default settings are probably fine, so you can just hit Next and the next screen too.

4. On the last screen, hit "Save Settings and Run Backup". Windows will make its first backup of your drive, during which you don't want to turn off your computer. After that, it'll make regular backups in the background as you work—you don't need to deal with it again.
