Part 1: Why Won't My iPhone Back Up?

If your iPhone doesn't back up data to iTunes, iCloud or a computer, there are multiple potential causes.

iPhone and iCloud storage is full. If the storage on iPhone and in iCloud is full, the backup won't be successful.

Poor network connection. A poor network connection can be a potential reason for the failure of a successful backup to iCloud.

iCloud is not working. The issue could be with iCloud itself. If the iCloud server is down, the backup will not be initiated.

iPhone isn't connected to Wi-Fi. Usually, iCloud backs up iPhone automatically when the iPhone is locked, connected to Wi-Fi, and charged. If iPhone isn't connected to Wi-Fi, backup will be impossible.

You are signed to a different iCloud account. If you are signed into an account other than the one associated with the device, the iPhone won't back up.

The connection is unstable. There could be an unstable connection between your iPhone and computer or a corrupted USB port.

iTunes is outdated. You're using an outdated version of iTunes; bugs may be causing your backup to fail.

Antivirus. Some antivirus programs can make connections with other devices from your computer difficult. That's why you must use anti-virus software that brings maximum protection but also allows smooth connections and communications.

The backup folder is damaged/corrupted. If iTunes alerts you that your iPhone cannot be backed up due to a lack of storage, even though there appears to be plenty available on the computer, it likely indicates an issue with the backup folder. This can occur if the iTunes backup folder is damaged or corrupted somehow.

With that, let's head to solutions to resolve the problem.

Part 2: What to Do If My iPhone Won't Back Up to iCloud/iTunes/Computer?

Your iPhone won't back up to iCloud, iTunes, or a computer? Then what danger will you probably encounter? Lose your important data. Thus, you need to address the backup hiccup swiftly.

1. Ensure iPhone is Connected to the Wi-Fi

iCloud backup is known to work on Wi-Fi due to the number of files that can be stored in a single backup. Even if your phone has unlimited data, it's generally slower than Wi-Fi, meaning the backup could take days. Here is how to connect your iPhone to Wi-Fi:

Step 1: On iPhone, click on the Settings app to open it. Then find the "Wi-Fi" option at the top and tap on it.

Step 2: Click on the Wi-Fi you would want to connect your iPhone to.

Step 3: Enter the Wi-Fi password if asked and click "Join" at the top right side of the screen.

If your iCloud backups fail, it could be because you don't have enough free storage space in the cloud. To figure out how much storage is left, here's what to do:

Step 1: Open the Settings app on your iPhone and click on your profile at the top.

Step 2: Click "iCloud". At the top of the menu, you will see the status of iCloud storage.

This may seem an obvious thing. But, with all the adjustable settings on iPhones, enabling or disabling a feature is easier without even realizing it. Fortunately, this dilemma has an effortless fix. To ensure your iPhone automatically backs up to iCloud, verify that the backup setting option has been enabled on your device. Here is how to switch on the iCloud backups option on iPhone:

Step 1: Open the "Settings" menu on your iPhone, click on your name, and scroll down to tap "iCloud".

Remember, when you log out of iCloud on your iPhone, any file kept in your iCloud will be removed from the iPhone but still in iCloud. So, before signing out, you will be asked to keep a copy of these files on the iPhone.

Signing out of iCloud means that your device is only removed from Apple's servers, blocking the sharing and updating of data between your phone and their servers. All the data preserved in iCloud will remain safe and secure, and iCloud will continue to sync across other devices linked to that same iCloud account.

5. Reset Settings

Still having difficulty backing up iPhone data to iCloud? Why not try resetting the settings? This process does not delete your data or content from your device. It will only erase system settings such as accessibility settings, Wi-Fi passwords, and more. Doing this might help clear up any settings interfering with the backups in iCloud. So, give it a go by following these steps:

Step 1: Open "Settings" on your iPhone. Head to "General" > "Transfer Or Reset iPhone".

Step 2: Look for "Reset" and select the option of "Reset All Settings". Confirm to proceed with this action. Once your device has restarted, carry out an iCloud backup once again.

13. Check for Any Issues with the PC's Security Software

Constantly, we are advised to use an antivirus program on computers to protect our data. Nonetheless, the settings of these programs may restrict connection and prevent backing up processes. To determine if it's your security software creating these troubles, check if the iPhone is authorized from the help menu and adjust the settings accordingly. Furthermore, you can temporarily turn off your security software while backing up data.

14. Check for Storage Space on Computer

An iPhone can store a substantial amount of data, so it shouldn't be a surprise that backing up all this information can take up quite a bit of your computer's disk space. Suppose you receive an error when attempting to back up your iPhone, claiming there isn't enough room on the hard drive. In that case, this indicates there simply isn't enough storage capacity for the full backup.

Free up some storage by erasing old files from your computer. To do this quickly and easily, delete older iPhone backups using iTunes.

Step 1: Navigate to the "Edit" menu and select "Preferences". A dialogue box will appear, prompting you to choose the "Devices" tab.

Step 2: From here, pick an outdated backup and hit "Delete Backup". If there are many backups stored on your device, you can delete many of them.
