Here’s how to back up iPhone/iPad to external drive

It is obvious that backing up your iPhone/iPad devices plays an important part. However, the limited disk space on your Mac or computer may serve as a major obstacle for your iPhone/iPad backups. But not to worry, the solution is an external hard drive that offers you more abundant space to keep your data backed up. Now we will walk you through how.

First and foremost, you will need a USB cable to connect your computer to the external hard drive. Now just get started.

Step 1: Connect your external hard drive to the computer. Your external drive should have enough space for the backup(s). You need to create a new folder on the drive with a catchy name like iPhoneiTunesBackups to be able to find the folder easily.

Step 2: Open a new Finder window by pressing Command + Spacebar and typing Finder, then selecting File > New Finder window.

In this new Finder window, hit Command+Shift+G and enter the following path:

~/Library/Application Support/MobileSync/

Step 3: This will take you directly to the folder we will be working with. Locate the folder named Backup and create a copy.

Step 4: Now find the folder you just created, then paste the copy from Step 3 into the folder on our drive. (in this example, the folder named iPhoneiTunesBackups)

Step 5: The folder must be accurately copied.

Now get back to the original folder (at ~/Library/Application Support/MobileSync/) and rename the folder to BackupOld or something like that.

step 5.1

 

You can delete this folder, but we recommend you should keep it in case you want to get back to the original.

Step 6: Launch the Terminal app by hitting Command + Spacebar and typing Terminal, then entering the path:

ln-s/Volumes/MYPASSPORT/iPhoneiTunesBackups/Backup/ ~/Library/Application Support/MobileSync

You need to change the sections after Volumes to go with the the name of your external drive and the name of the folder on the external drive. Now hit enter/return. Quit Terminal

Step 7: After quitting Terminal, to check whether it’s successful, you have to repeat Step 2. If the steps are successfully, you will see the Old Backup folder as well as the new, copied Backup folder with an arrow pointing to it. This means this Folder is now connecting to the Folder on your external drive.

Step 8: Open iTunes and connect your iOS device to it. In the Backups section, click on This Computer and select Back Up Now. This new backup data will be stored on the external hard drive if the above steps were done correctly.

Step 9: Check whether the data is backed up on your external hard drive. You will see the new files in the folder Backup if successful.

step 9

 

Later on, whenever you back up your device to your computer, iTunes will transfer data to the external hard drive if you’re connecting it to a computer.

If you do not want to back up to your external hard drive, you just need to return to the path ~ / Library / Application Support / MobileSync / and delete the folder with an arrow on it, then rename the old folder to Backup.
