Changing your iTunes backup location helps you manage storage and keep important data safe. When your startup disk is nearly full, redirecting backups to an external drive or secondary SSD can make syncing and restore processes smoother.
This guide walks through how to change the default iTunes backup folder, confirm the new path on Windows and macOS, and troubleshoot common issues related to device backups.
| Platform | Default Backup Path | How to Redirect | Verification Step |
|---|---|---|---|
| Windows 10 | C:\Users\Username\AppData\Roaming\Apple Computer\MobileSync\Backup | Set via environment variable or symbolic link | Check folder path in iTunes preferences |
| Windows 11 | C:\Users\Username\AppData\Roaming\Apple Computer\MobileSync\Backup | Use symbolic link after stopping iTunes services | Create a new backup and inspect file location |
| macOS | /Users/Username/Library/Application Support/MobileSync/Backup | Use Terminal to move and relink the folder | List files in the new directory to confirm |
Why you should change the iTunes backup directory
By default, iTunes stores device backups in a hidden user folder, which can fill up your system drive over time. Redirecting the backup location keeps your primary partition clean and ensures faster disk performance when running daily tasks.
An external drive or larger secondary partition gives you more room for multiple backup sets, especially if you sync several iOS devices or keep older versions for troubleshooting.
How to change iTunes backup location on Windows
Stop background services before moving files
Before relocating the folder, pause iTunes and related Apple services to prevent locked files and incomplete backups. Open Task Manager and end any iTunes or Apple Mobile Device Helper processes.
Then use Command Prompt with administrative rights to create a symbolic link that points from the default path to your chosen directory. This method keeps iTunes looking in the expected location while storing files on another drive.
How to change iTunes backup location on macOS
Use Terminal to move and relink the backup folder
On macOS, the Library folder is hidden by default, so you must reveal it through Go or Finder preferences. Copy the entire MobileSync folder to your external drive or an internal volume with more space.
Open Terminal to remove the original folder and create a symbolic link that directs macOS to the new path. Verify the setup by checking file ownership and permissions so iTunes can read and write backups without errors.
Confirming the new iTunes backup path
Check settings and generate a test backup
Open iTunes, navigate to preferences and devices sections, and review the stored backup path where available. The most reliable confirmation is to start a new backup of your iPhone or iPad and then browse the target directory to see fresh files being created.
Key steps to change and verify your iTunes backup location
- Stop iTunes and Apple-related services to avoid file locks.
- Move the MobileSync folder to your desired external or secondary drive.
- Create a symbolic link from the default path to the new location.
- Confirm permissions and ownership on macOS for smooth access.
- Generate a test backup and verify files appear in the new directory.
- Keep at least one original backup until you confirm the new setup is stable.
FAQ
Reader questions
Can I move an existing iTunes backup to a new drive safely?
Yes, you can copy the entire backup folder to the new location and then create a symbolic link from the original path to the copied folder. This preserves your previous backups and allows iTunes to access them as if they were never moved.
Will changing the backup location delete my current backups?
No, moving or copying the folder does not automatically delete data. You should verify that files were copied completely and that permissions are correct before deleting the originals to avoid any loss of recovery options.
Why does iTunes still save to the old path after I created a symbolic link?
This usually happens when services are still running or when the link points to a non-existent target. Restarting iTunes and related helper services, and double-checking the link destination, usually resolves the mismatch.
Can I use a network share for iTunes backups instead of a local drive?
It is generally not recommended because network latency and interruptions can cause corrupted backups. Local drives or external SSDs are more reliable, while network locations may work only for storage archives that you manage manually.
