Method 2. How to Back Up iPhone to an External Drive with the Symlink Method

If you want a free and effective way to learn how to back up an iPhone to an external hard drive without using third-party software, the Symlink method is a smart solution. This technique redirects the default iTunes or Finder backup folder to your external hard drive. Instead of saving backups on your computer’s internal storage, your system will automatically store them on the external drive. While this method requires a few technical steps, it’s free and works well on both Windows and macOS.

Step 1.
Make sure your external hard drive is recognized by plugging it into your computer. Find the backup folder for the default iPhone.

On Windows:

Go to:

C:\Users\[YourUsername]\AppData\Roaming\Apple Computer\MobileSync\Backup

On Mac:

Open Finder >Click Go in the menu > Hold Option > Click Library >

Go to:

Application Support/MobileSync/Backup

The backup folder should be moved to an external drive. Make a copy of the backup folder in its entirety, then transfer it to your external disk. Rename the original Backup folder on your computer (for example, to “Backup-Old”) as a precaution.
Step 3.
Create the Symbolic Link

On Windows:

Open Command Prompt as Administrator.

Type the following command:

mklink /J "C:\Users\[YourUsername]\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\Backup"

(Replace E:\Backup with your actual external drive path.)

On Mac:

Open Terminal.

Enter the command:

ln -s /Volumes/ExternalDrive/Backup ~/Library/Application\ Support/MobileSync/Backup

(Replace “ExternalDrive” with your drive name.)

Enter The Command Mac
