Open the iTunes app on your PC and click on the Phone icon from the same row that has Library, For You, Browse, Radio, and Store tabs.

How to change your backup location on Windows 11

Before proceeding, it’s recommended that you make a copy of the original iTunes backup folder located at one of the following addresses on your PC.

C:\Users\%userprofile%\%appdata%\Apple Computer\MobileSync\Backup

With that out of the way, let’s jump to the main procedure.

Press the Windows key on your keyboard to open the start menu.

In the start menu, search for cmd and click on Run as administrator. Confirm the UAC prompt to launch CMD as an administrator.

Now, make the new directory using the mkdir command. For example, if we want to store future iTunes backups in a folder called new_backups located in the C drive, we’ll enter the following command and press Enter:

mkdir c:\new_backups

Change your current directory to the newly-created directory. In the case of this guide, the command for that will be cd followed by the address of the new directory, i.e cd c:\new_backups. Enter this command and press Enter from your keyboard.

Now, locate the original iTunes backup directory and delete it. This directory will be present at one of the following locations on your PC.

If you installed iTunes from Microsoft Store:

C:\Users\%userprofile%\Apple\MobileSync

If you installed iTunes from Apple’s official website:

C:\Users\%userprofile%\%appdata%\Apple Computer\MobileSync

Back in the cmd app, create a symlink between the original and the new directory by entering one of the following commands in cmd, based on your system.

Note: Remember, you have to replace c:\new_backups with the location of the new directory created by you on your system. mklink /J “c:\Users\"userprofile"\Apple\MobileSync\Backup” “c:\new_backups”

If you installed iTunes from Apple’s official website:

mklink /J “c:\Users\"userprofile"\AppData\Roaming\Apple Computer\MobileSync\Backup” “c:\new_backups”

Your backup directory for iTunes backups will now have been changed on Windows 11. 

Difference between iTunes and iCloud backup

Before plunging into the irreversible acts of deleting iTunes backups on your Windows 11 PC, it’s important to have a cognizance of the 2 backup options offered by Apple: iTunes backup and iCloud backup. Let’s try to understand their differences.

iTunes Backup

An iTunes backup is a full backup of your iOS device and includes your purchased apps, music, movies, etc. You won’t need to re-download them every time you restore a backup. Additionally, iTunes backup also allows you to encrypt the backup. This encryption allows you to protect your backup from getting accessed by unauthorized users on the same PC or Mac.

iCloud Backup

While iTunes uses the local storage of your Windows or Mac systems, iCloud, however, is a cloud-based storage service. iCloud is a hands-free, automated, and cloud-based backup storage service, your backups are always encrypted to give you an additional layer of security.

Apple provides only 5GB of default storage per Apple ID for iCloud but you can increase this capacity by opting for one of the paid plans offered by Apple. 

iCloud backs up only the essential data, namely: App data, Device settings, Home Screen and app organization, iMessage, Photos, videos and Purchase history from your services, etc.
