2. Other Solutions to Fix iTunes Could Not Backup or Restore
Apart from iMyFone iTransor we would like to introduce you to the following solutions in order to troubleshoot the problems with iTunes. As iTunes could not backup or restore the iPhone because an error occurred while reading from or writing to the iPhone, these solutions would help you to a great extent in minimizing any kind of inconvenience for you while restoring or backing up iPhone data.
2.1. Update iTunes
When iTunes could not backup or restore iPhone, the out-dated iTunes might be the reason. Ergo, we advise you to check if the iTunes is updated. If not, update it right away to get the backup and restore process done smoothly. Here is how you can do this. Follow the steps according to the PC you own.
- Launch iTunes and click on 'Help' from the menu bar.
- Choose 'Check for Updates' and install the latest iTunes' version if any updates available.
- Go to the 'App Store' in your Mac.
- Now, choose 'Updates' option at the top.
- Look if there is any update present. If yes, then make sure to install it.
2.2. Delete or Move the Old iTunes Backups
You can either delete or move the old backup files from iTunes to fix this issue. Deleting corrupted backups will make iTunes work for you.
- For Windows, go to 'Edit' > 'Preferences' > 'Devices' > 'Delete Backup'.
- And for Mac, open 'iTunes' > 'Preferences' > 'Devices' > 'Delete Backup'
If you don't want to delete the files, just right click on the backup file and click on 'Show in Finder' option and simply move that particular backup file to some other location.
2.3. Try Another Computer
Maybe the computer you are making use of is the culprit. You can try the backup process using another computer. This should work if the problem is with the system. Take help from your friend by borrowing his/her computer.
2.4. Clean the Space of Your Computer
If still you get the pop-up error "The iTunes could not backup the iPhone because an error occurred while reading from or writing to the iPhone", please note that iOS backups take at the minimum of 1 or 2 GB space. Considering this, we would like to suggest you to free up your system's space. Make sure to clear up at least 5 GB space in your system.
2.5. Using iCloud
Here is the last recommendation. You can try iCloud for backup and restore if iTunes could not backup or restore iPhone due to reading and writing error. However, iCloud only offers 5GB of storage which could also restrict you to backup data beyond this size. The solution is, you can purchase more space if you have the more data than 5 GB. This method is a little time consuming. Another thing you should bear in mind is that iCloud backup process will need a stable and powerful internet connection. Therefore, you should take help of iCloud as a last resort if iTune fails to make backup due to reading/writing error.
