If you can't back up your iOS or iPadOS device to a computer or restore it from a backup
If you can't back up your iPhone, iPad, or iPod touch to a computer, or if you can't restore your device from a computer backup, learn what to do.
Try again after each step
Connect your device to your computer with a USB cable, and locate your device on your computer. If your device doesn't appear in Finder or iTunes, learn what to do. If you forgot your passcode or your device is disabled, learn what to do.
Restart all your devices.
If you use a Mac, skip this step. If you use a Windows PC and iTunes won't respond or your backup never finishes, you might need to update, change, disable, or uninstall your security software.
If an alert says that an error occurred
If an alert says there's not enough disk space
If a message says there’s not enough disk space when you try to back up your device, free some space on your Mac or PC. If you still see a disk-space error after you free enough space, contact Apple Support.
If an alert says that your backup is corrupt or incompatible
If your iOS or iPadOS device can't restore from a backup because the backup is corrupt or incompatible, make sure that your computer is updated. If you see an error that says your iOS or iPadOS software is too old, find out how to update your device to restore the backup. If you still can't restore the backup, you might not be able to use that backup. Try to use an alternate backup or an iCloud backup, or Contact Apple Support for more help.
