How to change the iPhone backup directory in iTunes

iTunes backup iPhone

Mac users may have noticed there is no built-in way to change where iTunes writes backup information. This means every time an iPhone, iPad or iPod touch is backed up to the computer using iTunes, it automatically uses the local drive. Rest assured, it is possible to tell iTunes to put backups on an external drive. Once the steps below are implemented, all iOS backup data will be saved to the new location.

To trick iTunes into putting backups on an external USB or eSATA drive, the standard backup location must be linked to a folder named "Backup" on the external drive. Also, once the old backup directory is renamed, it can be moved to the external drive, which saves additional storage on the computer. Follow these instructions to change the iTunes backup location on OS X or macOS:

  1. In the Finder navigate to Applications -> Utilities -> Terminal and open the Terminal app.
  2. Applications Utilities Terminal icon
  3. Go to the MobileSync directory on your Mac by entering the following command at the Terminal prompt:

    cd ~/Library/Application\ Support/MobileSync

  4. Terminal change directory MobileSync
  5. Rename the old iTunes backup folder with the command:

    mv Backup old-itunes-backup

  6. Create the new iTunes backup directory on your external drive. Note: Always replace "pingo/ios-backup" with the name of your own drive and folder:

    mkdir /Volumes/pingo/ios-backup/Backup

  7. Create a symbolic link with the command:

    ln -s /Volumes/pingo/ios-backup/Backup ~/Library/Application\ Support/MobileSync/Backup

  8. Terminal create symbolic link
  9. You can check the symbolic link using:

    ls -l

  10. Terminal check symbolic link Backup
  11. To free more storage space on the Mac, you can move the old iTunes backup from your computer to the external drive:

    mv old-itunes-backup /Volumes/pingo/ios-backup/.

  12. Once the above steps are complete, run an iTunes backup of your iOS device.
  13. iTunes run local iOS backup
  14. Open a Finder window and navigate to the external drive. Check the new backup directory to verify iTunes successfully wrote backup data to the new location.
  15. Check new iTunes backup directory

From now on, make sure this external drive is mounted to the Mac before running an iTunes backup.

Thanks Fred! You brought an end to a couple of hours of frustration as the old method using the Symlink was not working on Sierra.

Hi, I made mistake, when I check (step 6) symbolic link: I get: lrwxr, etc on pingo..... how do I delete that again via terminal so I can address again to my own name of ext. HDD?

To be clear: how can I delete a symbolic link and make a new one (or overwrite)?
