iPhone X Backup: iCloud and Computer Steps

To back up an iPhone X, use iCloud over Wi-Fi or connect the phone to a Mac or Windows PC and make a computer backup. iCloud is convenient for automatic backups; a computer backup is useful when you want a local copy, and you can make both for extra flexibility.

Choose iCloud or a computer backup

An iPhone backup saves information and settings so you can restore them if the phone is replaced, lost, damaged, or erased. It is not necessarily a complete duplicate of every item on the device: data already synchronized with services such as iCloud Photos may be handled separately from the backup.

iCloud: The phone can back up automatically while connected to Wi-Fi, charging, and locked. You can restore from the backup during setup of an iPhone.
Mac: Use Finder on a Mac running macOS Catalina or later. On older macOS versions, use iTunes.
Windows PC: Use the Apple Devices app where available, or iTunes. The app’s available features depend on the software installed on the computer.

For important data, keeping both an iCloud backup and a computer backup provides another recovery option. A computer backup can be encrypted to include additional sensitive information, but its password must be remembered to restore that encrypted copy.

Back up iPhone X to iCloud

Connect the iPhone X to a Wi-Fi network and open Settings.
Tap your name at the top, then tap iCloud. On some iOS versions, the backup control may appear as iCloud Backup directly on this screen; otherwise, tap iCloud Backup in the iCloud settings.
Turn on Back Up This iPhone or iCloud Backup, depending on the wording shown.
Tap Back Up Now and keep the phone connected to Wi-Fi until the process finishes. The screen shows the time of the latest successful backup.

To allow automatic backups, leave the feature enabled. Apple’s usual conditions for automatic iCloud backups are that the iPhone is connected to power and Wi-Fi and its screen is locked. A backup can take longer than expected if the connection is slow or there is a large amount of new data.

Check available storage under Settings > your name > iCloud. If there is not enough space, the backup will not complete. You can review what uses storage, remove an old device backup you no longer need, or upgrade the available iCloud storage. Before deleting a backup, make sure it is not the only copy you may need to restore.

Back up to a Mac or Windows PC

A computer backup is stored on the computer rather than in iCloud. Connect the iPhone X using a compatible cable, unlock it, and approve the trust prompt if it appears. The phone may ask for its passcode. If a connection prompt does not appear, unlock the iPhone and check that the cable and computer port work.

On a newer Mac: Open Finder and select the iPhone in the sidebar under Locations. If prompted, choose to trust the device on both the Mac and iPhone.
On a Windows PC: Open Apple Devices if installed, select the iPhone, and open its general or backup settings. If you use iTunes instead, open it and select the device icon.
Choose the option to back up all of the iPhone’s data to this computer, then select Back Up Now.
Wait for completion before disconnecting. Check the displayed latest-backup date or the backup details in the app.

Menu labels can vary slightly between versions of macOS, Windows, and Apple’s device-management apps. If the iPhone does not appear, try another cable or port, unlock the phone, respond to the trust prompt, and restart the computer and phone. Make sure the computer’s software is up to date enough to recognize the device.

Encrypted backups and what they include

In Finder, Apple Devices, or iTunes, you can select Encrypt local backup or similarly worded encryption setting before starting a computer backup. Encryption can preserve additional data, including saved passwords and some health and Wi-Fi information, that an unencrypted computer backup does not include. The exact contents can depend on the data type and settings.

Set a password you can keep securely. The password is required to use that encrypted backup, and Apple cannot recover a forgotten backup password for you. If you turn on encryption, the computer may remember it for later backups, but you should still retain the password somewhere safe.

Some information may not be duplicated in a backup because it is already synchronized or stored elsewhere. For example, iCloud Photos and iCloud Drive content generally sync through iCloud rather than being copied as ordinary iCloud backup data. Items such as downloaded media may need to be downloaded again. A backup also does not replace checking that important photos, files, and contacts are present in the service where you expect them.

Common backup problems and checks

iCloud says there is not enough storage: Review the backup size and what is using iCloud space. Remove data only if you are sure you no longer need it, or use a computer backup instead.
Backup seems stuck: Keep the iPhone on a reliable Wi-Fi network and connected to power. Allow more time, especially for the first backup or one containing many photos and videos.
The computer does not recognize the phone: Unlock the iPhone, accept the trust prompt, check the cable and port, and reopen Finder or the relevant Windows app.
There is no recent backup date: Start a manual backup and wait for its completion message. A setting being switched on does not prove that a backup has finished successfully.

Do not erase or trade in the iPhone until you have confirmed that a recent backup completed and that you can access the Apple Account or computer used for it. A backup is most useful when you know where it is stored and can still sign in to restore it.

Restore from an iPhone X backup

To restore an iCloud backup, begin setting up the iPhone and follow the prompts until Transfer Your Apps & Data or the equivalent setup screen. Choose the option to restore from iCloud, sign in with the Apple Account used for the backup, and select the backup by date. Keep the device connected to Wi-Fi and power while content downloads; some apps and data may continue restoring afterward.

For a computer backup, connect the iPhone to the Mac or PC that holds the backup, open Finder, Apple Devices, or iTunes, select the device, and choose Restore Backup. If the backup is encrypted, enter its password. Restoring replaces the iPhone’s current contents with the selected backup, so save any newer data you want to keep before proceeding.

Frequently Asked Questions

How do I know if my iPhone X backed up?
For iCloud, open Settings > your name > iCloud > iCloud Backup and check the latest successful backup time. On a computer, check the device’s backup details in Finder, Apple Devices, or iTunes.

Can I back up my iPhone X without Wi-Fi?
iCloud backups require a network connection and are normally made over Wi-Fi. A computer backup uses a cable connection to the Mac or PC, so it does not require Wi-Fi for the backup itself.

Does an iPhone backup save my photos?
Photos may be included in a backup when they are stored on the iPhone and are not already synchronized through a service such as iCloud Photos. Check your photo-sync settings and verify important pictures are accessible separately.

How much iCloud storage does an iPhone X backup need?
It varies with the data on the phone and what is already synced or excluded. iPhone settings show an estimate of the next backup size; compare it with your available iCloud storage before starting.

Can I back up an iPhone X to a Windows computer?
Yes. Connect the phone by cable and use Apple Devices or iTunes, select the iPhone, and start a computer backup. You can enable local backup encryption if you want its additional data coverage and can safely retain the password.
