How to change the device backup location of iTunes

Storage capacity of iOS devices keeps on increasing, and if you own multiple iOS devices and an MBP with limited storage like me, then you’ll definitely have issues with your backups. The best way to solve this is to transfer the location. For this tutorial, I will change the backup location to an external drive.

Before we proceed, make sure that your terminal have administrative privileges. If you don’t know how to do it, you can see this post.

rm -rf ~/Library/Application\ Support/MobileSync/Backup
mkdir -p /Volumes/Seagate\ Bac/BACKUP/MobileSync/Backup
ln -s /Volumes/Seagate\ Bac/BACKUP/MobileSync/Backup ~/Library/Application\ Support/MobileSync/Backup

If you open the local backup directory, you should see a folder with an arrow icon like this:

And, when you click it, you should be redirected to the target backup location.

Tip: Make sure that the target backup location is always plugged in everytime you’re going to backup your devices.
