Solution #1 – Purchase More Storage

Apple gives everyone with an iCloud account a small amount of storage for free. Most people find this to be enough space for a couple of backups. But if your iPhone is full of data and you responsibly back it up on a regular basis, the free storage will quickly fill up.

Fortunately, Apple sells iCloud storage at reasonable monthly rates. Users can purchase this either through a web browser or on their iPhone.

  • #1 – Unlock your iPhone and open the Settings app.
  • #2 – Tap your name at the top of this menu and then tap “iCloud.”
  • #3 – Next, select “Manage Storage” and tap “Change Storage Plan.”
  • #4 – Several upgrade options are available here. Tap the upgrade you’d like and then tap “Buy” at the top-right.
  • #5 – Enter your iCloud password and proceed to complete the payment stage.

Obviously, the drawback to this is that you’ll be paying monthly for the storage. Even considering this, the pricing of extra iCloud storage is far from expensive.

Solution #2 – Delete Unneeded Backups

If spending money is the last resort, deleting any old backups from your account will help. Realistically only the most recent backup is necessary. It’s reassuring to have multiple backups, but not entirely necessary.

  • #1 – Open the Settings app and tap your iCloud account.
  • #2 – Go to “iCloud > Manage Storage > Backups“.
  • #3 – All iPhone backups will be listed with their file sizes. Take a moment to explore the backups and decide which ones to delete.
  • #4 – Tap on a backup to delete and at the bottom of this menu, press “Delete Backup.”
  • #5 – Confirm that the backup should be removed from your iCloud storage.

Even just wiping one or two backups will aide iPhone backup failed. There will be an increase in available iCloud storage, and taking backups shouldn’t cause errors anymore.

Solution #3 – Update iOS Version

Let’s be honest: as important as iOS updates are, seeing that “Software Update” notification causes a rush of anxiety. Sure, big updates usually include new and exciting features. But minor updates are less so.
Why people have a distaste towards iOS updates is simple. When updates are installing, we can’t use our iPhones. Sadly not keeping the iOS version up-to-date can result in iPhone backup failed due to software communication conflictions.

  • #1 – Open Settings and go to the “General” menu.
  • #2 – Tap “Software Update,” and if there’s a new update available, tap “Install.”
  • #3 – It will now download, and once it finishes, your iPhone will install.
  • #4 – Wait while the new firmware installs and afterward check if you can take a backup.

Usually, we’d suggest that users back up their iPhone before updating the iOS version. Considering the backup failed error, backing up isn’t an option so be cautious of data loss occurring.

Solution #4 – Change iCloud Settings

Human error can’t be ignored, and it could be that you turned off the iCloud backup setting. Enabling it once again is easy and doable from your iPhone.

  • #1 – Launch the Settings app.
  • #2 – Tap your iCloud name at the top of this screen.
Change iCloud Backup Settings
  • #3 – Tap “iCloud” and swipe to the bottom of this menu.
  • #4 – Look for “iCloud Backup” and select it.
  • #5 – If the slider is not green, tap it to enable the iCloud Backup feature.
  • #6 – Once it is enabled, tap “Back Up Now” to take an iCloud backup.

This setting is on by default. So, if you turn it off at any time, remember to return to the iCloud settings and reenable it to avoid further backup problems.

Solution #5 – Sign Out of iCloud

Authentication errors are another reason that you might run into iPhone backup failed. These errors don’t always alert you and can affect iCloud features negatively. Signing out of your iCloud account and signing back in will reauthenticate your iPhone’s access and secure a connection with Apple servers.

  • #1 – Start by launching the “Settings” app and tapping your iCloud account.
  • #2 – Swipe down and tap on the “Sign Out” button. Follow the confirmation steps to agree with the account removal.
  • #3 – Back on the Settings menu, tap the iCloud banner and sign in using your account email and password.
  • #4 – Go to “iCloud > iCloud Backup” and enable the feature if it isn’t already.
  • #5 – Tap “Back Up Now” to see if the issue is gone.
Sign out of iCloud

When we sign in to iCloud on a new iPhone, we assume that’s it. As you can see through, sometimes signing out and back in can revalidate the iCloud connection and resolve common problems.

Solution #6 – Investigate Network Issues

Last of all, network connection problems can interfere with an iCloud connection, and thus, it may be behind iPhone backup failed. Try the following:

  • Connect to a different Wi-Fi network
  • Enable airplane mode for a few minutes, then disable it
  • Check if other iPhones can take backups on the network
  • Restart your router (if other devices experience network issues too)
  • Use your data plan to take a backup instead of Wi-Fi
  • Try taking a backup on iTunes

If you discover that backup failed is limited to your iPhone, resetting the network settings is the next step. Here’s how to do so:

  • #1 – Go into the Settings app and tap “General.”
  • #2 – At the bottom of this menu, tap on “Reset” and choose “Reset Network Settings.”
  • #3 – Enter your device’s passcode to confirm this action.
  • #4 – Your iPhone will now restart as part of the network reset.
  • #5 – Once the device loads up, reconnect to Wi-Fi, and check if a backup can be taken.

This completely wipes all network settings. You will have to reconnect to any Wi-Fi network you were connected to and possibly reconfigure your carrier settings.
