My iPhone backup keeps failing
---- I have switched on iCloud backup on my iPhone but every day it says iPhone backup failed and You do not have enough space in iCloud to back up this iPhone. That didn’t happen a few days ago. Why did this happen? How can I stop it?
- Question from an Apple User
Backing up iPhone is very important when you use iPhone. The backup could rescue a corrupt iPhone or let you restore information if iPhone is lost, broken, or encounter another issue. iCloud is usually used to backup iPhone. Because it is a network application, iPhone backup issues often appear when you create iPhone backup. There are just a few options when you enable iCloud backup so you might feel confused if any problems happen.
Generally, not enough space on iCloud is the most common cause of iPhone backup failing. As known to us, the Apple only provide 5 GB of free space of each user. In addition, if you iPhone is a weak network condition, the iPhone backup may get stuck. It can be the another reason.
Next, you can refer to the following content to solve this problem.

iCloud backup failed mostly for not enough storage. One Apple ID has just 5GB of free storage. That means your iPad or other iPhone could also use the 5GB of storage. If your family are using the same Apple ID with you, their backups might have occupied most of the space. When your iCloud storage is almost full, you should check the available iCloud backup storage:
Go to iPhone Settings > [your name] > iCloud > Manage Storage
You could see the usage of iCloud storage here. Usually, photos and iCloud backups take most of the storage. If you find that something is no longer needed, you could tap it and then delete it.
If you find that there is 1GB of left iCloud storage, and you think it is enough for you to save iPhone, you could check the estimated iPhone backup size in iCloud settings:
Go to Manage Storage > Backups > [device name]
iCloud would estimate the next iPhone backup size. iPhone Settings doesn’t take much storage, so you don’t have to consider that and there are also no options for you to cancel that. App data often takes much storage, and iCloud doesn’t know which app is important, so the options are offered to you. When you check the iPhone backup size, the apps would be listed and how much storage that every app takes has been calculated. You can simply uncheck the unimportant apps to change the iPhone backup size.
You might have enabled iCloud backup in settings and are sure that there is enough space in iCloud, but iPhone never backs up itself. In fact, iCloud backup would be triggered only under a specific situation.
iCloud backup means transferring data when the Internet is connected, so to avoid affecting other network applications, iPhone would do that at night. Except for that, you have to lock the screen to tell iPhone you are not using it and connect iPhone to power to make sure iCloud backup would not be canceled for low power. The most important thing is that you should make sure your Wi-Fi is stable because your router might reboot itself at night.
If you are sure the network is ready, you could also create iCloud backup anytime you want:
Go to iPhone Settings > [your name] > iCloud > Backup to toggle on iCloud Backup and tap Back Up Now
Sometimes you might find that your iCloud stuck on estimating time. Or it just take a much longer time than expected. It would be disappointing if iPhone backup stop because everything happens online and you have no options but cancel backup. After you cancel the backup, you should go to iCloud > Manage Storage > Backups to check whether it is already completed. Some users reported this situation and attribute this to iOS bug. If you are lucky, you would find that your backup is already there.
Most of the time, iCloud backup is really stuck. You should restart iPhone to manually backup iPhone to iCloud. If the problem still exists, you could follow the tips below to reset the Network:
★ Connect iPhone to a better Wi-Fi
★ Go to iPhone Settings > General > Software Update to update iPhone
★ Go to iPhone Settings > General > Reset and select Reset Network Settings or Reset All Settings
