The simplest way to back up your iPhone on Windows

The fastest way to back up your iPhone on a Windows computer is through iTunes or the Apple Devices app, depending on which version of Windows you have. Both programs connect your iPhone to your computer with a USB cable and copy your photos, messages, settings, and app data to a folder on your hard drive. If something happens to your phone — a crack, water damage, or a lost device — you can restore everything from that backup.

Windows 10 and earlier use iTunes. Windows 11 uses the Apple Devices app, which works the same way but is built into the system. Either way, the process takes the same steps: plug in your phone, choose what to back up, and let the program finish. Most backups take 5 to 30 minutes depending on how much data you have.

Key Takeaways

  • iTunes (Windows 10 and earlier) or the Apple Devices app (Windows 11) creates a complete backup of your iPhone's data, photos, messages, and settings on your computer.
  • You need a USB cable that works with your iPhone model and a Windows computer with enough free space — usually at least 5 to 10 gigabytes.
  • The backup process is automatic once you plug in your phone and click the backup button, and you do not need an Apple ID or internet connection to create a local backup.
  • You can restore from a backup if you get a new iPhone, replace a broken one, or recover data you accidentally deleted.

What you need before you start

You need three things: your iPhone, a USB cable that fits your phone, and a Windows computer with iTunes or the Apple Devices app already installed. If you have Windows 10 or earlier, read iTunes from Apple's website — it is free. If you have Windows 11, the Apple Devices app is already there; open the Microsoft Store and search for "Apple Devices" if you cannot find it.

Check that your computer has enough free space. A full iPhone backup usually takes 5 to 10 gigabytes, but if you have a lot of photos or videos, it can be larger. Right-click your C: drive, choose Properties, and look at the free space shown. If you have less than 20 gigabytes free, delete old files or programs first.

Make sure your USB cable works. Plug it into your computer first, then into your iPhone. Your phone should show a notification asking if you trust this computer — tap Trust. If nothing happens, try a different USB cable or a different USB port on your computer.

How to back up with iTunes on Windows 10

Open iTunes and plug your iPhone into your computer with the USB cable. Your phone should appear in iTunes as a device icon near the top left. Click that icon to open your phone's settings page.

On the left side, click Backups. Under "Manually Back Up and Restore," click Back Up Now. iTunes will start copying your data. You will see a progress bar at the top of the window. Do not unplug your phone until the backup finishes — this usually takes 5 to 30 minutes.

When the backup is done, the progress bar disappears and iTunes returns to normal. Your backup is now saved on your computer. You can unplug your phone. To check that the backup worked, go back to the Backups section — you should see today's date listed under "Latest Backups."

How to back up with the Apple Devices app on Windows 11

Open the Apple Devices app and plug your iPhone into your computer with the USB cable. The app will recognize your phone and show it on the screen. Click your device name to open its settings.

Look for the Backup section. Click Back Up Now. The app will start copying your data, and you will see a progress indicator. Leave your phone plugged in until the backup finishes — this usually takes 5 to 30 minutes.

When the backup is complete, the progress indicator disappears. You can unplug your phone. To confirm the backup worked, return to the Backup section — you should see today's date listed as the most recent backup.

Where your backup is stored and how to find it

iTunes and the Apple Devices app store your backup in a hidden folder on your computer. You do not need to find this folder to restore your phone — the programs handle that automatically. But if you want to see where it is, you can look in your user folder.

On Windows 10, go to C:\Users\[Your Username]\AppData\Roaming\Apple Computer\MobileSync\Backup. On Windows 11, the Apple Devices app stores backups in C:\Users\[Your Username]\AppData\Local\Packages\AppleInc.AppleDevices_[random numbers]\LocalCache\Local\Apple\MobileSync\Backup. These folders are hidden by default. To see them, open File Explorer, click View at the top, and check "Hidden items."

You do not need to move or copy these folders. They are safe where they are. If you want to back up your backup — a copy of your copy — you can copy the entire Backup folder to an external drive or cloud storage.

How to restore your iPhone from a backup

If you get a new iPhone or need to restore an old one, you can put all your data back from the backup you created. Plug your new or restored iPhone into your computer with the USB cable. Open iTunes or the Apple Devices app and click your device.

Look for the Restore option. Click Restore Backup, then choose the backup date you want to use. The program will ask you to confirm — click Restore again. Your phone will restart and begin copying data from the backup. This can take 15 minutes to an hour depending on how much data you have. Do not unplug your phone during this process.

When the restore finishes, your phone will restart again and show your home screen. All your apps, photos, messages, and settings will be back exactly as they were when you created the backup.

What gets backed up and what does not

A local backup on your Windows computer includes almost everything: your photos and videos, messages and call history, app data and settings, contacts, calendar events, notes, reminders, and your home screen layout. It also includes your passwords and Wi-Fi networks, though some apps may need you to sign in again after you restore.

A few things do not back up this way. Apps themselves are not included — when you restore, your phone will re-read them from the App Store. Very large video files or files stored only in the cloud (like OneDrive or Google Drive) may not be included. If you use iCloud, some data may already be backed up there separately, so you have two copies in different places.

Troubleshooting common backup problems

If iTunes or the Apple Devices app does not recognize your iPhone, the USB cable is usually the problem. Try a different cable, or try a different USB port on your computer — avoid USB ports on the front of your computer if you have them, and use the ones on the back instead. If your phone still does not appear, restart both your phone and your computer, then try again.

If the backup starts but gets stuck, check your internet connection — even though you do not need the internet to create a backup, a slow or broken connection can sometimes cause problems. Unplug your phone, close iTunes or the Apple Devices app, restart your computer, and try again. If the backup keeps failing at the same point, your hard drive may be full or damaged — check your free space and run a disk check.

If you see an error message about trust, your phone is asking permission to share data with your computer. Unplug your phone, unlock it, plug it back in, and tap Trust when the notification appears. If the notification does not appear, go to Settings on your iPhone, tap General, then About, and look for a Trust option there.

Frequently Asked Questions

Do I need an Apple ID to back up my iPhone on Windows?

No. A local backup on your Windows computer does not require an Apple ID or an internet connection. You only need the USB cable and iTunes or the Apple Devices app. If you want to use iCloud backup instead, that requires an Apple ID, but that is a different method.

Can I back up my iPhone to two different computers?

Yes. You can plug your iPhone into multiple Windows computers and create a separate backup on each one. Each computer will have its own backup folder. If you restore from one computer's backup to your phone, then plug into a different computer, that second computer will create a new backup of the restored data.

How often should I back up my iPhone?

Back up whenever you have made changes you do not want to lose — after adding new photos, installing apps, or changing important settings. Many people back up once a week or once a month. The more often you back up, the less data you lose if something goes wrong.

What if my iPhone is broken and will not turn on?

You cannot create a new backup from a broken phone, but if you have an older backup on your Windows computer, you can restore it to a replacement iPhone. Plug the new phone into your computer, open iTunes or the Apple Devices app, and choose Restore Backup. Your old data will go onto the new phone.

Is a Windows backup the same as iCloud backup?

No. A Windows backup is stored only on your computer's hard drive. iCloud backup is stored on Apple's servers in the cloud. Both back up similar data, but they are separate — you can have both, or just one. A Windows backup is faster and does not use your iCloud storage space.
