If the backup of your iPhone is corrupt, you will usually find it in two ways: 1.When you try to make a backup, an error message appears: "iTunes can not save the iPhone because the backup was corrupted or incompatible with the iPhone". 2.When you try to restore the backup of your iPhone, an error message appears: "iTunes can not restore the iPhone because the backup was corrupted or incompatible with the iPhone being restored". We will list several methods to repair the iPhone backup if a corrupt or unsupported message, both in the event that you get a corrupted backup error when trying to backup or if you need to restore a corrupted backup in iTunes.
Many iDevice users found themselves in the same situation that an iPhone backup could not be restored. What probably happened there was a corrupted or incompatible iTunes / iCloud backup. Here are some clues provoking this error.
1) Backup failure without people's notice
when creating a backup with iTunes, some errors may occur but you have not received a message. Then, you thought that the backup had gone smoothly with iTunes until the next attempt to restore the backup files from iTunes. Unfortunately, you were told that the backup was corrupt.
2) Incompatibility of the iOS version
also different iOS versions on your iDevice cause the problem. For example, you can not restore an iOS 6 backup on iPhone6. Or sometimes, you've created an iTunes backup of the iPhone 6 under iOS 9.1, but after upgrading to iOS 9.3, restoring the backup with iTunes fails due to iOS update issues.
