Many users feel frustrated with the way iTunes manages (or essentially fails to manage) iOS devices. You’d be surprised by the amount of emails we receive daily saying that their iPhone won’t backup to iTunes. To make our life easier, we decided to summarize all iTunes backup issues in one place and provide the actual solutions.
If you are reading this, it means that you probably got an iTunes error message while trying to back up your iPhone, iPad, or iPod. We found that most iTunes backup errors can be resolved by several easy solutions we listed in this article.
This article features iTunes errors and solutions that should help you to backup your iOS device:
- iTunes errors
- iTunes could not backup because the backup was corrupt or not compatible
- iTunes could not backup the iPhone because the backup was corrupt
- iTunes could not backup the iPhone because not enough free space is available on this computer
Here’s a list of the most common errors in iTunes:
- “iTunes cannot backup iPhone because an unknown error occurred -1.”
- “iTunes cannot backup iPhone because the backup session failed.”
- “iTunes cannot backup iPhone because the iPhone refused the request.”
- “iTunes cannot backup iPhone because an error occurred.”
- “iTunes cannot backup iPhone because a session could not be started.”
- “iTunes cannot backup iPhone because the backup could not be saved on this computer.”
Most issues that cause iTunes backup errors occur either on the side of your iPhone or your PC.
- Restart iPhone. Begin by restarting your iPhone, iPad, or iPod Touch with which you experience the trouble. This solution may bring a quick fix. As you are on a roll, we’d recommend restarting your PC too.
- Install the latest iTunes version. Your PC requires iOS drivers so it can correctly recognize your iPhone. Getting the most recent version of iTunes will make sure you have the latest drivers.
As a substitute for iTunes, you can install the required drivers with CopyTrans Drivers Installer.
Connect iPhone to PC via another USB slot. And unplug any other USB devices before attempting to back up again.
Deactivate security software. Temporarily disable your antivirus and firewall programs and try to back up once more.
Free up hard drive space. Most iOS backups require at least 1 or 2 GBs of free space on your system drive. If you can’t back up because your computer is low on memory, we recommend you free up at least 5 GB from your primary computer drive.
Alternatively, you can backup your iPhone to an external hard drive.
Delete previous iOS backup entries. iTunes may fail to back up the iPhone due to a previous backup entry being corrupted. Delete that backup by following the steps in the below image.
If your backup is corrupt and you don’t want to lose your precious data, you can extract data from a corrupt backup.
If the solutions above fail to help you solve the problem, it may quickly become complicated. Our experience shows that even Apple Support may not be able to help.
iTunes could not backup because the backup was corrupt or not compatible
When you backup your device with iTunes, the backup can turn out corrupt due to various reasons like connectivity issues, or you may have unplugged your device too early. iTunes also fails to check the data integrity of your backup, and later you can end up with nothing on your hands. As a result, you cannot make a new backup based on the previous one that is corrupt. Is there a way around this issue?

iTunes could not backup the iPhone because not enough free space is available on this computer
The error message reads: “iTunes could not back up the iPhone because not enough free space is available on this computer” suggesting deleting files from the computer and the Recycle Bin.
