The fastest way: use iTunes or the Apple Devices app

Windows does not have built-in iPhone backup the way macOS does. Instead, you use iTunes (if you have Windows 10 or older) or the Apple Devices app (if you have Windows 11). Both let you plug in your iPhone and save everything—photos, messages, settings, app data—to your computer in one step.

iTunes is a standalone program you read from Apple's website. The Apple Devices app comes pre-installed on Windows 11 and handles the same backup job. If you are on Windows 10, iTunes is your only local option; if you are on Windows 11, you can use either one, though the Apple Devices app is newer and simpler.

The backup file itself is encrypted and stored on your hard drive. You can restore from it later if your iPhone is lost, broken, or replaced. This backup includes everything except photos and videos stored in your camera roll—those sync separately if you use iCloud Photos, or you can copy them manually to your computer.

Key Takeaways

  • iTunes (Windows 10 and older) or the Apple Devices app (Windows 11) are the only ways to back up an iPhone locally on Windows.
  • Plug in your iPhone with a USB cable, trust the computer when prompted on your phone, and click the backup button—the process takes 5 to 30 minutes depending on how much data you have.
  • The backup file is encrypted and stored on your computer's hard drive, separate from iCloud backups.
  • Photos and videos in your camera roll are not included in the backup file unless you manually copy them or use iCloud Photos.
  • If you lose or replace your iPhone, you can restore from the backup file to put everything back the way it was.

Step-by-step backup with iTunes on Windows 10

read iTunes from apple.com/itunes if you do not have it already. Install it, then plug your iPhone into your Windows computer with a USB cable. Your iPhone will show a prompt asking "Trust This Computer?"—tap Trust and enter your passcode.

Open iTunes. Your iPhone should appear in the top left corner of the window. Click it. In the left sidebar, click Summary. Under the Backups section, you will see two options: "iCloud" and "This Computer." Select "This Computer," then click "Back Up Now." iTunes will start copying your data. Do not unplug your phone until the progress bar finishes.

The backup usually takes 5 to 30 minutes depending on how much is on your phone. When it is done, you will see the date and time of the backup listed under "Latest Backups." That backup file is now stored on your computer's hard drive, typically in a hidden folder that iTunes manages automatically—you do not need to find it or move it.

Step-by-step backup with the Apple Devices app on Windows 11

The Apple Devices app is built into Windows 11, so you do not need to read anything. Plug your iPhone into your computer with a USB cable. When the "Trust This Computer?" prompt appears on your phone, tap Trust and enter your passcode.

Open the Apple Devices app (search for it in the Start menu). Your iPhone will appear. Click it, then click the Backup button. The app will show a progress bar as it copies your data. Like iTunes, this usually takes 5 to 30 minutes. When it finishes, you will see the backup date and time listed in the app.

If you are on Windows 11 but prefer iTunes instead, you can still read and use it—both programs store backups in the same location, so you can switch between them without losing your backup history.

What gets backed up and what does not

A local backup includes your contacts, calendars, messages, notes, reminders, app data, home screen layout, settings, and passwords. It also includes any apps you have installed, though the app files themselves are re-downloaded from the App Store when you restore—the backup stores only your settings and data within each app.

Photos and videos in your camera roll are not included in the backup file. If you want to back those up to your computer, you can either copy them manually using File Explorer (your iPhone appears as a device when plugged in), or use iCloud Photos to sync them to the cloud instead. Messages with photos and videos are included in the backup, but the original camera roll files are not.

Health data, HomeKit data, and some app-specific information may or may not be included depending on how the app stores it. If you want to be certain about a specific app, check its settings to see if it offers its own backup or export option.

Where the backup file is stored on your computer

iTunes and the Apple Devices app store backup files in a hidden folder on your hard drive. On Windows, this is usually at C:\Users\[Your Username]\AppData\Roaming\Apple Computer\MobileSync\Backup. You do not need to access this folder to back up or restore—iTunes and the Apple Devices app handle it automatically.

If you want to see the folder, you need to show hidden files in File Explorer. Right-click in File Explorer, select View, then check "Hidden items." Navigate to the path above and you will see a folder with a long string of letters and numbers—that is your backup. Do not move, rename, or delete it unless you are sure you do not need it anymore.

If you are running low on hard drive space, you can delete old backups by opening iTunes or the Apple Devices app, going to Preferences (iTunes) or Settings (Apple Devices app), and selecting the backup you want to remove. Keep at least your most recent backup in case you need to restore.

How to restore from a backup

Plug your iPhone into your computer and open iTunes or the Apple Devices app. If you are setting up a new iPhone for the first time, the setup wizard will ask if you want to restore from a backup—select your computer backup from the list. If you are restoring to an existing iPhone, open the Summary tab (iTunes) or click your phone (Apple Devices app) and look for a Restore option.

Choose the backup you want to use—the app will show you the date and size of each one. Click Restore and enter your Apple ID password if prompted. The restore process takes 10 to 45 minutes depending on how much data is being copied back. Your phone will restart during the process. Do not unplug it until it finishes and you see the home screen again.

After the restore completes, your iPhone will look exactly as it did when the backup was made—same apps, same settings, same messages, same everything. Apps will re-read from the App Store in the background over the next few hours.

iCloud backup versus local backup on Windows

iCloud backup and local backup are separate things. iCloud backup stores your data on Apple's servers in the cloud; local backup stores it on your Windows computer's hard drive. You can use both at the same time, and many people do.

iCloud backup happens automatically if you turn it on in Settings > [Your Name] > iCloud > iCloud Backup on your iPhone. Local backup only happens when you plug in and click the backup button. If your iPhone is lost or stolen, iCloud backup is more useful because you can restore to a new phone without needing your old computer. Local backup is useful if you want a copy on your own hardware that you control, or if you do not want to rely on cloud storage.

If you have both iCloud and local backups, you can restore from either one. iTunes and the Apple Devices app will show you all available backups—local ones are labeled with your computer name, and iCloud ones are labeled "iCloud."

Troubleshooting common backup problems

Your iPhone does not appear in iTunes or the Apple Devices app: Make sure you are using an official Apple USB cable, not a third-party one. Try a different USB port on your computer. Restart both your iPhone and your computer. If you still do not see it, uninstall and reinstall iTunes (or restart Windows 11 if using the Apple Devices app).

The backup keeps stopping or failing: This usually means your USB connection is unstable. Try a different cable and a different port. Make sure nothing else is using your iPhone—close all apps and do not touch it during the backup. If your hard drive is almost full, the backup may fail; delete unnecessary files to free up space and try again.

You forgot your backup password: If you encrypted your backup (iTunes asks this during setup), you cannot restore without the password. You will need to set up your iPhone as new and then manually restore your data. To avoid this in the future, write down any backup password you create and store it somewhere safe.

The backup file is taking up too much space: Each backup is a complete copy of your iPhone's data, so if your phone has 128 GB of data, the backup will be roughly 128 GB. If you need to free up space, delete old backups and keep only the most recent one. You can also switch to iCloud backup instead, which stores data on Apple's servers rather than your hard drive.

Frequently Asked Questions

Can I back up my iPhone to Windows without iTunes?

No. iTunes (Windows 10 and older) or the Apple Devices app (Windows 11) are the only official ways to back up locally to Windows. iCloud is the alternative if you do not want to use a cable, but that stores your backup on Apple's servers, not your computer.

Do I need to back up to both iCloud and my computer?

No, but many people do for extra safety. One backup is enough. If you use iCloud, you do not need a local backup. If you prefer to keep your data on your own hardware, a local backup is sufficient.

Will backing up delete anything from my iPhone?

No. Backing up only copies data from your iPhone to your computer. Nothing is removed from your phone. The backup is a separate file that sits on your hard drive.

Can I back up my iPhone to multiple computers?

Yes, but each computer will have its own separate backup file. If you back up to Computer A and then to Computer B, Computer B will not have the backups from Computer A. You can restore from any of them, but they are independent copies.

What should I do if my backup file gets corrupted?

If iTunes or the Apple Devices app says your backup is corrupted, you cannot restore from it. Delete the corrupted backup and create a new one. If you have an iCloud backup, you can restore from that instead. Going forward, keep multiple recent backups so you have options if one fails.
