Setting Up Your External Drive for iPhone Backup

To back up your iPhone to an external drive, there are a few steps you’ll need to follow. These steps include preparing the drive, configuring your Mac, and creating a symlink to redirect backups.

Preparing the External Drive

First, connect your external hard drive to your Mac using a USB cable or adapter. Ensure the drive has enough space for your iPhone backup.

Next, format the external drive if needed. Open Disk Utility, select the drive, and choose format. Opt for Mac OS Extended (Journaled).

After formatting, create a dedicated folder for iPhone backups. This helps keep files organized and easy to find later.

Configuring MacOS for External Backup

To back up iPhone data to your external drive, change the location of iTunes or Finder backups. Open Finder and select your iPhone under Locations.

In Manage Backups, right-click your iPhone’s backup and select Show in Finder. Drag the backup folder to the external drive.

Use Terminal for more control. Open Terminal and enter commands to change the backup destination permanently. Grant Full Disk Access in System Preferences for the best results.

Creating a Symlink to the External Drive

A symlink lets your Mac save backups straight to the external drive. First, locate the backup folder on your Mac: ~/Library/Application Support/MobileSync/Backup.

Open Terminal and type the following:

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

This moves the existing backup and creates a symlink. Now, backups will go directly to the external drive. Remember to verify the backup by checking the files on the external drive. This ensures everything is in the right place.
