You can back up your iPhone directly to a Mac or Windows computer using iTunes or Finder, storing everything locally instead of in iCloud

When you back up your iPhone to your computer instead of iCloud, you create a complete copy of your phone's data — photos, messages, settings, app data — that lives on your hard drive rather than Apple's servers. This approach gives you full control over where your data sits and how long you keep it. The process differs slightly depending on whether you use a Mac or Windows computer, and whether your Mac runs an older or newer operating system.

A local backup is useful if you want to avoid iCloud subscription costs, prefer not to store data on Apple's servers, or need a backup method that works without an internet connection. It also lets you keep multiple backup versions on your computer if you have the storage space.

Key Takeaways

  • On a Mac running Monterey or newer, open Finder, plug in your iPhone, and click the backup option under General settings.
  • On a Mac running Catalina or older, use the iTunes process instead of Finder to create and manage backups.
  • On Windows, read iTunes from Apple's website, connect your iPhone, and select the backup option in the device menu.
  • Your computer must have enough free storage space for the full backup, which is typically several gigabytes depending on your iPhone's content.
  • Backups created this way are encrypted by default if you set a backup password, protecting sensitive data like saved passwords and health information.

How to back up on a Mac with Finder (Monterey and newer)

If your Mac runs macOS Monterey, Ventura, or Sonoma, Finder handles iPhone backups instead of iTunes. Connect your iPhone to your Mac using the USB cable that came with your phone or any compatible Lightning or USB-C cable. Your iPhone may ask you to trust this computer — tap Trust and enter your passcode if prompted.

Open Finder and look for your iPhone in the sidebar under Locations. Click your iPhone's name. In the General tab, you will see a Backup section. Choose "Back up all of the data on your iPhone to this Mac" and click Back Up Now. The backup process usually takes 5 to 30 minutes depending on how much data you have. Do not disconnect your iPhone until the progress bar completes.

If you want to encrypt your backup so it includes saved passwords, health data, and home kit information, check the box labeled "Encrypt local backup" before you start. You will need to create a password for this encrypted backup.

How to back up on a Mac with iTunes (Catalina and older)

Older Macs running Catalina or earlier use iTunes instead of Finder. Open iTunes and connect your iPhone with a USB cable. iTunes will recognize your device and show it in the top menu bar. Click your iPhone's name to open the device summary page.

Under the Backups section, select "This computer" instead of iCloud. Click Back Up Now. The backup will begin when ready. Like the Finder method, this typically takes several minutes to half an hour. Leave your iPhone connected until the backup finishes — you will see a completion message in iTunes.

To encrypt your backup, check "Encrypt iPhone backup" before starting. This protects sensitive information that would otherwise be excluded from local backups.

How to back up on Windows

Windows computers do not have Finder or a built-in backup tool for iPhones. You need to read iTunes from Apple's website first. Go to apple.com/itunes, read the Windows version, and install it. Open iTunes once installation finishes.

Connect your iPhone to your Windows computer using a USB cable. If your iPhone asks you to trust this computer, tap Trust and enter your passcode. iTunes will detect your device and show it in the top menu bar. Click your iPhone's name to open the device summary.

Under Backups, select "This computer" and click Back Up Now. The backup process works the same way as on Mac — it will take several minutes to complete depending on your data volume. You can encrypt the backup by checking "Encrypt iPhone backup" before you start, which is recommended if your computer is shared with others.

What gets backed up and what does not

A local backup includes your photos, videos, messages, contacts, calendar events, notes, app data, settings, and voicemail. It also captures your home screen layout, wallpaper, and accessibility settings. Anything stored in iCloud — like iCloud Photos or iCloud Drive files — is not included in a local backup because it already exists on Apple's servers.

Some data never backs up to your computer, whether you use iCloud or local backups. This includes content you are actively streaming (like music from Apple Music), data from apps that store information only in the cloud, and anything protected by app-specific security settings. If you rely on iCloud Photos, those images will not appear in a local backup unless you have also downloaded them to your iPhone's local storage.

Storage space and backup location

Before you start a backup, check how much free space your computer has. Your backup file will be roughly the same size as the data on your iPhone. If your iPhone shows 64 GB of storage used, you need at least 64 GB of free space on your computer. Go to About This Mac (on Mac) or Settings > System > Storage (on Windows) to check available space.

On a Mac, backups are stored in ~/Library/process Support/MobileSync/Backup/. You do not need to navigate there — Finder and iTunes manage the files automatically. On Windows, backups go to \Users\[Your Username]\AppData\Roaming\Apple Computer\MobileSync\Backup\. Again, iTunes handles this folder for you, so you do not need to touch it directly.

If you want to keep multiple backups, you can copy the backup folder to an external hard drive or cloud storage service like Google Drive or Dropbox. This creates a second copy separate from your computer's main drive, which protects against data loss if your computer fails.

Restoring from a local backup

When you need to restore your iPhone from a local backup, connect it to the same computer where you created the backup. Open Finder (Mac Monterey and newer) or iTunes (Mac Catalina and older, or Windows). Click your iPhone's name and go to the Summary or General tab.

Click Restore Backup. A list of available backups will appear, showing the date and time each was created. Select the backup you want to use and enter your backup password if you encrypted it. The restore process will erase your iPhone and install everything from the backup, which usually takes 10 to 30 minutes. Your iPhone will restart several times during this process — this is normal.

Frequently Asked Questions

Can I back up my iPhone to multiple computers?

Yes, but each computer stores a separate backup. If you back up to your work Mac on Monday and your home Mac on Wednesday, you will have two different backups on two different computers. This is useful for redundancy, but it means you need to remember which computer has the most recent backup if you need to restore.

What is the difference between an encrypted and unencrypted backup?

An unencrypted backup excludes passwords, health data, and home kit information for security reasons. An encrypted backup includes everything but requires a password to restore. If you encrypt your backup, write the password down somewhere safe — you cannot restore from an encrypted backup without it.

Do I need to keep my iPhone plugged in the whole time?

Yes, your iPhone must stay connected to your computer from start to finish. If the cable disconnects before the backup completes, the backup will fail and you will need to start over. Use a cable you trust and avoid moving your iPhone during the process.

Can I back up my iPhone if I forgot my passcode?

No. Your iPhone will ask you to unlock it before allowing a backup to proceed. If you have forgotten your passcode, you will need to restore your iPhone using recovery mode before you can back it up again.

How often should I back up my iPhone?

This depends on how much your data changes. If you take photos daily or receive important messages, backing up weekly or monthly is reasonable. If your iPhone content rarely changes, backing up every few months is sufficient. Many people back up before major iOS updates or before traveling, just in case something goes wrong.
