Where Are iTunes Backups Stored?

iTunes backups are stored in a hidden folder on your computer: on Windows, they are in %APPDATA%\Apple Computer\MobileSync\Backup, and on macOS, they are in ~/Library/Application Support/MobileSync/Backup. These folders contain encrypted or unencrypted backup files for your iPhone, iPad, or iPod touch, created when you sync or back up via iTunes or Finder.

Why iTunes Backups Exist

Before iCloud backups became common, iTunes was the primary way to back up an iOS device to a local computer. Even today, many users prefer local backups because they are free, do not require internet, and can be restored without waiting for a download. iTunes (and on macOS Catalina and later, Finder) creates a full snapshot of your device’s settings, app data, messages, photos, and more, stored in a single folder with cryptic subfolder names.

Locating the Backup Folder on Windows

On Windows 10 and 11, the backup folder is hidden by default. To find it:

1. Open File Explorer.
2. Click the View tab and check Hidden items.
3. Navigate to C:\Users\[YourUsername]\AppData\Roaming\Apple Computer\MobileSync\Backup.

Alternatively, press Win + R, type %APPDATA%\Apple Computer\MobileSync\Backup, and press Enter. You will see a list of folders with names like 00008101-001D1A1E0A0A801E. Each folder corresponds to a specific device backup.

Locating the Backup Folder on macOS

On a Mac, the folder is also hidden. To access it:

1. Open Finder.
2. Press Cmd + Shift + G (Go to Folder).
3. Type ~/Library/Application Support/MobileSync/Backup and press Enter.

The ~ represents your home folder. If you do not see the Library folder in Finder, this shortcut will still work. Each device’s backup is stored in a subfolder with a similar alphanumeric name.

How to Identify Which Backup Belongs to Which Device

The folder names are not human-readable. To identify a backup, look at the file Info.plist inside each backup folder. Open it with a text editor or plist viewer; it contains the device name, iOS version, serial number, and the last backup date. On Windows, you can use a plist editor like Notepad++ with the XML plugin, or simply search for “Device Name” in the file.

Managing Backup Storage Space

Backups can consume significant disk space, especially if you have multiple devices. To see how much space a backup takes, right-click the folder and select Properties (Windows) or Get Info (Mac). If you need to free space, you can delete old backups, but be careful: deleting a backup removes that snapshot permanently. To delete a backup properly, use iTunes or Finder’s Manage Backups option rather than manually deleting folders, as this avoids potential corruption.

Encrypted vs. Unencrypted Backups

When you back up via iTunes or Finder, you can choose to encrypt the backup by checking Encrypt local backup and setting a password. Encrypted backups are stored in the same folder but are not accessible without the password. They include more data, such as saved passwords, health data, and HomeKit settings. Unencrypted backups are simpler but do not include these sensitive items. If you forget the password, the only way to reset it is to erase the device and start fresh—there is no way to recover the data.

Common Problems and Solutions

• Backup folder not visible: Ensure hidden files are shown. On Windows, enable Hidden items; on Mac, use the Go to Folder command.
• Backup fails with error 54: This often means the backup is corrupted. Delete the backup folder and try again, but note that you will lose the old backup.
• Not enough space: Move the entire Backup folder to an external drive, then create a symbolic link (junction) from the original location to the new one. This requires command-line knowledge; otherwise, use a third-party tool.
• Cannot restore from backup: Ensure the backup is from a compatible iOS version. If you updated iOS, older backups may still work, but newer backups cannot be restored to an older iOS version.

Frequently Asked Questions

How do I change where iTunes stores backups?

There is no built-in option to change the backup location in iTunes or Finder. You can move the folder manually and create a symbolic link, but this is advanced and not officially supported. Alternatively, use iCloud backups, which store data in the cloud and do not take local space.

Can I access the files inside a backup directly?

Not easily. The backup is stored in a proprietary format with hashed filenames and no file extensions. To extract specific data, you would need a third-party tool or forensic software. For most users, the backup is only useful for restoring the entire device via iTunes or Finder.

Why is my backup folder empty?

If you have never backed up to this computer, the folder will be empty. Also, if you use iCloud backups exclusively, no local backup is created. Check your iTunes/Finder preferences to see if local backups are enabled.

How often does iTunes create a backup?

iTunes creates a backup automatically when you sync your device, unless you have disabled it. You can also manually back up by right-clicking the device in iTunes and selecting Back Up Now. The frequency depends on how often you connect and sync.

Does deleting a backup free up space immediately?

Yes, deleting the backup folder (or using the Delete Backup option in iTunes/Finder) frees up space immediately. However, if you delete the wrong backup, you cannot recover it, so double-check the device name and date before deleting.
