Both iTunes and iCloud offer the way to help us backup iPhone data. When we accidentally lose some important data, we can perform a restore to get them back. We can also utilize it to transfer data to new iPhone and it’s also a way to fix iOS issues.

However, when you are trying to restore an iTunes or iCloud backup this time, a message appears and says that iPhone cannot restore from backup not enough free space is available on device. You may have tried to fix this error by restarting the computer & iPhone but it does not work. Well, take it easy. Get some other methods to this “iPhone restore failed not enough space error” in this guide.

How to Fix iPhone Restore Failed Not Enough Space Error?

Since it says that iPhone cannot restore from backup because of not enough space, first you should go to have a check the storage space of your iPhone or computer. It makes sense to see whether the error message is the reality.

If indeed there is not enough free space to perform the restore, you can try to free up more storage space. Or if there is enough available space on your device but receive the error message, please jump to the next part to get another solution.

Free Up iPhone Storage Space

You can check the usage of iPhone storage space by going to Settings > General > Storage & iCloud Usage. It will show you how much space is used by each app. To free up space, you can choose to delete some infrequently used apps. You can also remove unwanted songs, photos, videos, messages, etc.

Free Up Computer Storage Space

To free up the storage space of your computer, you can delete applications, photos, videos, large documents, etc. If you want to keep these files, you can move them to removable media, such as external hard drive, USB flash drive, or cloud storage. You can also run the Disk Cleaup utility to remove unnecessary files on your system hard drive.

Be aware that iTunes backup can occupy considerable space of your hard drive. So you can delete some old iTunes backup files. Two ways to make it:

■ Delete old backups via iTunes directly:

Open iTunes > Click Edit > Choose Preferences... > Click Devices tab > Select the backup you want to delete > Click Delete Backup to confirm.

Click Delete Backup

■ Delete old backups from backup location:

For PC: \Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\

For Mac: ~/Library/Application Support/MobileSync/Backup/

Delete From Backup Location

Note: If you see folders with a time stamp to the end of the backup library, please also delete them. These folders would be created during the restore process. Even when the backup fails, the folder will not be removed automatically.
