Part 1: Why is the Backup Session Failed on iTunes?

Why does iTunes keeps on saying backup session failed? The reasons for this issue can be traced back to various factors such as hardware-related issues or malware attacks. Here are a few potential reasons:

  • iTunes corruption: If the configuration file is missing on your PC, it may corrupt the iTunes application, resulting in data backup failure.
  • Insufficient iCloud storage: iCloud only provides 5GB of free storage. Once the free storage is full, you need to purchase additional storage or clean up iCloud storage.
  • Computer Error: Hardware-related issues can also cause the "iTunes backup session failed" error.
  • Antivirus software: Some antivirus programs are configured to automatically interrupt the backup and restore process.
  • Outdated iTunes version: Running an outdated version of iTunes can also cause backup session failure.

Now that you know the reasons, here are some solutions to help you troubleshoot and fix the issue that backup session failed on iTunes and let you resume the data backup process again.

Fix 2: Update iTunes

Older versions of iTunes can cause compatibility issues during the backup process. Therefore, making sure your iTunes software is up to date is crucial to resolving a failed backup session. Here's how to update iTunes:

For iTunes from the Microsoft Store

If you downloaded iTunes from the Microsoft Store, it will usually update automatically. To check and update manually:

  • Open the Microsoft Store on your computer.
  • Click Downloads and Updates to see when iTunes was last updated.

For iTunes from the Apple website

  • Open iTunes on your computer.
  • Go to the Help menu.
  • Select Check for Updates.
  • If an update is available, download and install the latest version of iTunes.

Fix 3: Check Windows Security Settings

Occasionally, antivirus software on your PC or Mac can interfere with the iTunes backup process, causing it to fail. To troubleshoot this issue, try temporarily disabling your antivirus and firewall programs before attempting the backup again.

Fix 4: Manage Old Backups

iTunes backup session failures can often be attributed to an out-of-date backup stored on your computer. This usually happens when iTunes references data from a previous backup, including encryption settings. To resolve this issue, verify that you had previously selected "Encrypt local backup" and make sure to do the same for the current backup to maintain privacy settings. Follow these steps to manage old backups:

  • Locate the iTunes backup folder:
  • For iTunes installed from the Microsoft Store:
    Path: C:\Users\YourUserName\Apple\MobileSync\Backup.

    For iTunes downloaded from the Apple website:
    Path: C:\Users\YourUserName\AppData\Roaming\Apple Computer\MobileSync\Backup.

  • If "Encrypt local backup" was enabled in the previous backup, make sure to select it again during the current backup to keep the privacy settings consistent.
  • Navigate to the backup folder you identified and view the contents of the old backup.
  • Delete any expired backups that may cause conflicts during the backup process. (How to delete iTunes backup?)
  • Utilize the iTunes backup browser to examine the contents of the backup for better management and troubleshooting.

Fix 5: Reset Lockdown Folder

Compatibility and violation issues are often the root cause of many problems with iTunes backup files. Resetting the lockdown folder can help resolve privacy issues. iTunes may access your iPhone since this folder contains the certificate for your device. Resetting it gives your computer permission to operate once more. Take these actions:

  • Close iTunes and unplug your iPhone from your laptop.
  • Locate the C:\ProgramData\Apple\Lockdown folder in iTunes Lockdown. By default, the ProgramData folder is hidden. To make it visible, click View in the top menu bar and select Hidden Items.
  • Close the window after deleting all files from the Lockdown folder.
  • Launch iTunes, connect your iPhone to your computer using a USB cable, and select Trust from the menu.
  • Try backing up your iPhone using iTunes again.
