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. Could you please help me get out of this?
- 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. 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.
This passage would introduce some common reasons for iCloud backup keeping failing. You could
follow the instruction to solve the problem that happened to you.
#1 iCloud backup keeps failing for
not enough storage
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.
#2 iCloud backup keeps failing for
not able to start
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

#3 iCloud backup failed for it is
stuck
Sometimes you might find that your iCloud could not complete. It could take hours or even
days. It would be disappointing if iCloud backup stuck because everything happens online and
you have no options but cancel backup. After you cancel iCloud 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 fix the
issue:
★ 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
