How to Change the Location of Your iPhone Backup

 HD icon

If you have any number of iOS devices, you likely back your stuff up onto your computer. Perhaps iCloud, but after a certain point, you may have so much stuff to back up that it’s best to just put it all on your computer than it is to pay for the additional iCloud storage. That’s especially the case if you have multiple iOS devices. You can save a lot of space on your drive if you have lots of iOS apps, etc. For instance, we were able to free up 100GB, no joke.


1) Make sure that iTunes is closed.

2) You will now move your folder called ~/Library/Application Support/MobileSync/Backup/ to the drive you want to back up to. For instance, an external drive or secondary drive within your computer. Whichever works for you.

3) Launch Terminal Applications/Utilities/Terminal and type in the following command line:

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

In the above example, ‘DriveName’ would be the name of the new backup location.

Windows XP

1) Ensure that iTunes in closed.

2) Download Junction (link) ( Or you can use MKlink for Windows here’s a rundown on that, which will make things a little different in the command prompt)

3) Unzip Junction.exe to your username folder, which is usually found in C:\Documents and Settings\

4) You will now create a folder for the your backups where you want them to save. From there, you will move your current backup folder to that new location.

a) The default location of that backup folder is here: C:\Documents and Setting\username\Application Data\Apple Computer\MobileSync  

b) You will now put it in the new location you want your backups to save to, such as an external drive.

5) Now run the Command Prompt and type the following:

junction "C:\Documents and Setting\<username>\Application Data\Apple Computer\MobileSync\Backup" "H:\Backups\iPhone Backup"

In the above example, “H:\Backups\iPhone Backup” should be your own file path leading to the backup location you want to use.

6) Close the Command Prompt and open iTunes and backup.

Windows Vista and Windows 7

1) Ensure that iTunes is closed.

2) Move the C:\Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\ to the drive you want to back up to. Let’s say Drive H:\ again

3) Open a command prompt and create an NTFS junction point something like what’s shown below:

mklink /J “C:\Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup” “h:\Backup”

There you go!

Now you can save a ton of space on your main hard drive by backing up your iOS devices onto an external drive. We freed up 100GB on our MacBook Pro.
