Fix 2. Update or Reinstall iTunes

If the first fix fails, the issue may lie with your iTunes. Your iTunes is too outdated to back up. To solve this, you can attempt to update iTunes to the latest version or uninstall it completely and then reinstall iTunes. To update iTunes, follow the steps below:

Step 1. Launch iTunes and select "Help" from the top menu of the iTunes window. Then, click on "Check for Updates".

Step 2. This will prompt the Apple software update window to appear. Check for any available updates. If a newer version of iTunes is found, click on "Download iTunes" to initiate the update process.

Fix 3. Reset the Lockdown Folder

Another cause of the backup session failure on iTunes is iTunes being unable to obtain permission from your computer. Resetting the Lockdown folder can resolve your issue. This folder is used to store the certificate from your device, allowing iTunes to read your iPhone. Here is how to do it:

For Windows:

Step 1. Close the iTunes application and disconnect your iPhone from the PC.

Step 2. Next, launch File Explorer and input "C:\ProgramData\Apple\Lockdown" into the search bar.

Step 3. Now, proceed to delete all files within the "Lockdown" folder.

Step 4. After that, restart iTunes, reconnect your iPhone to the PC, and attempt to create a backup for your files again.

For Mac:

Step 1. Close iTunes and disconnect your iPhone from your MacBook.

Step 2. Open Finder and choose "Go To Folder". Enter "/private/var/db/lockdown/" and hit "Enter".

Step 3. Delete all files from the Lockdown folder and attempt to back up your data through iTunes once more.

Fix 4. Disable Antivirus Program

In some cases, antivirus programs on your computer might mistakenly identify iTunes backup files as threats and prevent their creation. This can result in backup sessions failing. To address this issue, we can attempt to disable the antivirus program temporarily during the backup process and then proceed with the backup operation.
