Backing up your computer to an external hard drive on Windows 10 is a smart way to protect your important files from unexpected loss. To do this, connect your external hard drive to your computer, use File History or Backup and Restore (Windows 7) to select the files or system images you want to back up, and then let Windows do the rest. This way, you ensure that your data is safe and easily recoverable if needed.
How to Backup Computer to External Hard Drive Windows 10
Backing up your computer is essential to safeguarding your data. Here’s how to do it on Windows 10.
Step 1: Connect Your External Hard Drive
Plug your external hard drive into an available USB port on your computer.
Ensure the drive is properly detected by your Windows 10 system. You should see it appear in “This PC” under “Devices and drives.”
Step 2: Open Backup Settings

This section in Windows 10 is where you can set up and configure backup options, including File History and other backup settings.
Step 3: Set Up File History

Step 4: Choose Backup Frequency
Decide how often you want to back up your files: daily, weekly, or monthly.
Choosing the right frequency is essential. More frequent backups ensure that recent changes are saved, but it requires more storage space and time.

Windows 10 will start copying selected files to your external hard drive. This might take some time depending on the amount of data.
After completing these actions, your computer will regularly back up your selected files to the external hard drive. This means your data will be safe from accidental deletion or system crashes, and you can restore files quickly when needed.
