How to Back Up Your iPhone to a Windows PC

The fastest way to back up your iPhone to a Windows PC

The easiest method is to use iTunes (or the Music app on Windows 11) and a USB cable. Plug your iPhone into your PC with the cable that came with your phone, open iTunes or the Music app, select your device when it appears, and click "Back Up Now." The entire backup takes 5 to 30 minutes depending on how much data you have. This creates a complete copy of your phone's settings, photos, messages, and apps on your PC's hard drive.

If you prefer not to use a cable, iCloud is the wireless alternative. Turn on iCloud backup in your iPhone's Settings, and your phone backs up automatically when plugged into power and connected to Wi-Fi. However, iCloud stores the backup on Apple's servers, not on your PC itself — so if you want a copy physically on your Windows computer, the iTunes method is what you need.

Key Takeaways

iTunes (or the Music app on Windows 11) is the standard tool for backing up an iPhone to a PC using a USB cable.
A full backup includes your photos, messages, app data, settings, and contacts — everything needed to restore your phone if it breaks or is lost.
The backup process takes 5 to 30 minutes and happens on your PC's hard drive, not in the cloud.
You can also use iCloud for wireless backups, but those are stored on Apple's servers rather than on your computer.
Windows 11 users can use the Music app instead of iTunes; Windows 10 users should read iTunes from Microsoft Store or Apple's website.

Setting up iTunes or the Music app on your PC

If you use Windows 10, read iTunes from the Microsoft Store or from apple.com. If you use Windows 11, the Music app comes built in and handles iPhone backups — you do not need to install anything extra. Open whichever app you have, and leave it running before you plug in your phone.

The first time you connect your iPhone, Windows may ask you to trust the device. On your iPhone screen, tap "Trust" when the prompt appears. This allows your PC to read your phone's data. Without this step, iTunes or the Music app will not see your device.

Backing up with a USB cable step by step

Plug the USB-A end of your iPhone cable into a free USB port on your PC. Plug the other end into your iPhone's charging port. Wait a few seconds for your PC to recognize the device.

In iTunes (Windows 10) or the Music app (Windows 11), your iPhone's name should appear in the left sidebar or at the top of the window. Click on it. You will see a summary page with device information, storage usage, and backup options.

Under the "Backups" section, select "This computer" (not "iCloud"). Then click the "Back Up Now" button. A progress bar will appear showing how much of the backup is complete. Do not unplug your phone until the backup finishes — interrupting it can corrupt the backup file.

When the backup is done, the progress bar disappears and you see the summary page again. Your backup is now stored on your PC's hard drive, usually in a folder called Apple\MobileSync\Backup inside your user account's AppData folder (this folder is hidden by default, so you will not see it in normal file browsing).

What gets backed up and what does not

A full iTunes backup includes your photos and videos, messages and call history, contacts, calendar events, notes, reminders, voice memos, app data, home screen layout, and system settings. It also backs up any apps you have installed, though the backup stores only the app data — not the app itself, which your phone will re-read from the App Store if you restore.

Items that do not back up to your PC include content you bought from iTunes or the App Store (those are tied to your Apple ID and re-read automatically), photos in iCloud Photo Library (those sync through iCloud, not iTunes), and anything stored only in iCloud Drive or other cloud services. Health and fitness data backs up only if you have iCloud Health enabled.

Restoring from a backup on your PC

If you need to restore your iPhone from the backup you created, plug it into your PC again and open iTunes or the Music app. Click on your device, then look for a "Restore" button on the summary page. Click it and choose the backup you want to restore from — the app shows the date and time each backup was created, so you can pick the right one.

Your phone will restart and begin copying the backup data back onto it. This process takes 10 to 45 minutes depending on backup size. Your phone will restart several times during restoration — this is normal. Do not unplug it until the process is completely finished.

Scheduling automatic backups

You can set iTunes or the Music app to back up your iPhone automatically every time you plug it in. Open the app, click on your device, go to the summary page, and look for an option that says "Automatically back up when this iPhone is connected" or similar wording. Check that box and click "explore" or "Done."

From that point forward, every time you plug your phone in to charge or sync, a backup will run in the background. This is the easiest way to keep your PC backup current without thinking about it. The app will not back up if your phone is locked, so make sure to unlock it when you plug in.

Troubleshooting common backup problems

If iTunes or the Music app does not recognize your phone, try these steps in order: unplug the cable and plug it back in, restart both your PC and your iPhone, try a different USB port on your PC, and try a different USB cable if you have one available. Sometimes a cable becomes loose or damaged and stops working.

If you see an error message during backup, the most common cause is not enough free space on your PC's hard drive. Check how much space your backup will need (iTunes shows this on the summary page) and make sure your PC has at least that much free space available. You can free up space by deleting old files or moving them to an external drive.

If your backup keeps stopping partway through, your phone may be overheating. Unplug it, let it cool for 10 minutes, and try again. Also make sure your iPhone is not running other apps in the background — close all open apps before starting the backup.

Frequently Asked Questions

Can I back up my iPhone to multiple PCs?

Yes, but each PC will have its own separate backup. If you back up to PC A, then plug into PC B and back up there, PC B creates a new backup file that is independent from the one on PC A. You can restore from either backup, but they do not sync with each other. If you want one unified backup, use iCloud instead.

How much space does an iPhone backup take up?

A backup is roughly the same size as the amount of data on your phone. If your iPhone shows 64 GB of storage used, expect the backup to take up around 64 GB on your PC. iTunes shows the exact size before you start, so you can check whether your PC has enough free space.

What if I forgot my iPhone backup password?

If you encrypted your backup (iTunes asked for a password when you first backed up), you cannot restore from that backup without the password. You can create a new unencrypted backup going forward, but the old encrypted one is locked. Write down any backup password you create and store it somewhere safe.

Do I need to back up if I use iCloud?

iCloud and PC backups serve different purposes. iCloud backs up automatically over Wi-Fi and lets you restore to a new phone anywhere. A PC backup gives you a local copy you control and can restore from without internet. Having both is the safest approach, but if you only use iCloud, you still have a backup.

Can I back up just my photos instead of everything?

iTunes backs up everything or nothing — you cannot choose individual items. If you want to back up only photos, use File Explorer to copy them manually from your iPhone (it appears as a device in File Explorer when plugged in), or use iCloud Photos to sync them to the cloud instead.
