Introduction: Why Back Up an iPhone to a Computer? (And Skip iCloud This Time)
The Lifesaver We Call 'Backup'
In an era where smartphones are central to daily life, the data they hold—photos, messages, contacts, and more—is invaluable.
Regularly backing up an iPhone is a critical practice. It serves as a safety net, protecting against data loss due to device damage, loss, or unforeseen technical issues.1 Furthermore, backups are essential when transitioning to a new device or if a device needs to be restored to factory settings.2
Why Choose a Computer Over iCloud for Backups?
While Apple's iCloud service offers a convenient backup solution, some users prefer or require alternatives. Backing up an iPhone to a personal computer (Mac or Windows PC) presents several distinct advantages.
One primary benefit is enhanced control over data. When backing up to a computer, the data resides on a local hard drive, giving the user direct oversight of where their information is stored, which can be a significant factor for individuals with specific privacy preferences.
Computer backups can also be more comprehensive in certain respects. These backups are designed to include almost all of a device's data and settings.4 In contrast, iCloud backups primarily save data that is not already being synced with iCloud services.4 For instance, if iCloud Photos or iCloud Messages are not enabled, a computer backup is more likely to capture this data directly.
Storage capacity is another consideration. Most computers offer substantially more storage space than the complimentary 5GB provided by iCloud's free tier. While iCloud storage can be expanded, this incurs ongoing costs, whereas computer backup storage is limited only by the available space on the computer's hard drive.4 This means local backups can be a more cost-effective solution for users with large amounts of data.
The backup process itself can also be more efficient. Computer backups utilize a direct USB cable connection, which generally offers faster and more reliable data transfer compared to Wi-Fi-dependent iCloud backups, particularly for large initial backups or in environments with slow or unstable internet connectivity.6 This also means a Wi-Fi connection is not a prerequisite for performing the backup. A significant, often underappreciated, advantage of local computer backups is the ability to restore an iPhone even without an active internet connection. iCloud restores, conversely, necessitate a Wi-Fi connection 7, making local backups a more versatile option in situations like travel or during internet outages.
Finally, local computer backups avoid the subscription model associated with increased iCloud storage, representing a one-time investment in terms of computer storage space rather than recurring fees.
This guide acknowledges these common reasons users seek alternatives to cloud-based solutions and aims to provide clear, factual instructions for those looking to manage their iPhone backups locally.
What This Guide Will Cover
This document will provide detailed, step-by-step instructions for backing up an iPhone to both Mac computers (using Finder for modern macOS versions and iTunes for older ones) and Windows PCs (utilizing iTunes or the Apple Devices app). It will also explain how to enhance the security of these backups through encryption, detail what specific data is included, and offer practical tips for managing local backups effectively.
II. Getting Ready: The Essentials for a Smooth Backup
Before initiating an iPhone backup to a computer, a few preparatory steps and essential components are necessary to ensure the process is successful and efficient.
The iPhone and its Trusty USB Cable
A reliable physical connection between the iPhone and the computer is paramount. Users should ensure they have the original USB cable that accompanied their iPhone or a certified MFi (Made for iPhone) cable. Using uncertified or faulty cables can lead to intermittent connections and backup failures.8
The Computer
The software used for backing up an iPhone depends on the computer's operating system and its version. It's important for users to identify their computer's OS, as this dictates the required Apple software and the specific steps to follow.
-
For Mac Users:
-
If the Mac is running macOS Catalina (version 10.15) or any later version, backups are managed through Finder.
-
For Macs operating on macOS Mojave (version 10.14) or earlier versions, iTunes is the application used for iPhone backups.3
-
-
For Windows PC Users:
-
Backups are typically handled using iTunes or the more recent Apple Devices app.10
-
It is crucial to ensure that iTunes is updated to its latest version. If using the Apple Devices app, it should also be current. The Apple Devices app often works in conjunction with a streamlined version of iTunes that may still manage media libraries.8
-
Sufficient Storage Space on The Computer
iPhone backups, particularly the initial one which captures all selected data, can be quite large. It is essential to verify that the computer's hard drive has adequate free space to accommodate the backup file.8 If an alert indicates insufficient disk space during the backup attempt, users will need to free up space on their Mac or PC before proceeding.11
Time
The duration of an iPhone backup can vary. The first backup generally takes the longest, as it involves copying a significant amount of data. Subsequent backups are typically faster because they only save new or modified data since the last backup.6 The total time will depend on the volume of data on the iPhone and the speed of the computer and USB connection.2
For a successful connection and backup, the iPhone must "trust" the computer. When the iPhone is connected, a prompt may appear on its screen asking to "Trust This Computer." This authorization is a necessary security step. Additionally, on Windows systems, security software (such as antivirus or firewall programs) can sometimes interfere with the communication between the iPhone and the computer, or with the backup process itself.8 Users should be aware that temporary adjustments to such software might be needed if connection or backup issues arise.
III. Backing Up an iPhone to a Mac: Step-by-Step
The procedure for backing up an iPhone to a Mac varies slightly depending on the version of macOS installed on the computer.
A. If Using macOS Catalina (10.15) or Later (Using Finder)
For Macs running macOS Catalina or newer versions, Apple integrated iPhone management, including backups, directly into the Finder application.
-
Connect The iPhone: The iPhone should be connected to the Mac using a compatible USB cable.
-
Open Finder: The Finder icon, typically located in the Dock, should be clicked to open a Finder window.
-
Locate The iPhone: In the Finder sidebar, under the "Locations" section, the connected iPhone should appear. Clicking on the iPhone's name will select it.3 If the device does not appear, users should ensure it is unlocked and check the cable connection. A prompt to "Trust This Computer" may appear on the iPhone's screen; this must be accepted for the Mac to access the device.11 This "Trust" prompt is a security checkpoint, ensuring that the iPhone only permits data access to computers explicitly authorized by the user, thereby preventing unauthorized access.
-
Navigate to the General Tab: At the top of the Finder window displaying the iPhone's information, the "General" tab should be selected.3
-
Choose Backup Settings: Within the General tab, the option "Back up all of the data on your iPhone to this Mac" must be selected. This setting ensures that the backup is stored locally on the Mac.3
-
Secure The Backup (Highly Recommended): It is strongly advised to encrypt the local backup. This is achieved by selecting the checkbox labeled "Encrypt local backup".3
-
Upon selecting this option, a prompt will appear to create a password. A strong, memorable password should be chosen. It is critical to store this password securely, as it is impossible to restore from an encrypted backup without it. Apple cannot help recover this specific password if it is lost.3 The importance of encryption and this password will be discussed further.
-
-
Start the Backup: After configuring the settings, clicking the "Back Up Now" button will initiate the backup process.3
-
Monitor Progress: A progress bar will indicate the backup's status. The process should be allowed to complete without disconnecting the iPhone.
The shift from iTunes to Finder for device backups on macOS Catalina and later reflects Apple's strategy of de-bundling iTunes' functions into more focused applications. This change makes Finder a more central hub for device management on macOS, potentially offering a more streamlined experience for users familiar with Finder, though it may require adaptation for long-time iTunes users.
B. If Using macOS Mojave (10.14) or Earlier (Using iTunes)
For Macs running macOS Mojave or older operating systems, iTunes remains the tool for managing iPhone backups.
-
Connect The iPhone: The iPhone should be connected to the Mac via a USB cable.
-
Open iTunes: iTunes may open automatically upon connection. If not, it should be launched manually from the Applications folder.3
-
Locate The iPhone: A small iPhone icon will appear near the top-left of the iTunes window. Clicking this icon will access the device's management screen.3
-
Go to the Summary Tab: In the sidebar of the iTunes window (or at the top, depending on the view), "Summary" should be selected.3
-
Choose Backup Settings: In the "Backups" section of the Summary tab, the option "This Computer" must be selected to ensure the backup is stored locally.15
-
Secure The Backup (Highly Recommended): The checkbox for "Encrypt local backup" (or "Encrypt iPhone backup") should be selected.3
-
As with Finder backups, a strong, memorable password must be created and stored safely. This password is non-recoverable if forgotten and is essential for accessing the encrypted backup data.3
-
-
Start the Backup: Clicking the "Back Up Now" button will begin the backup process.3
-
Monitor Progress: The backup progress will be displayed in iTunes. The iPhone should remain connected until the process is complete.
IV. Backing Up an iPhone to a Windows PC: Step-by-Step
Windows PC users can also back up their iPhones locally using Apple's software. The primary application for this has traditionally been iTunes, though Apple has introduced the Apple Devices app, which works in conjunction with or as a partial replacement for some of iTunes' functionalities on Windows.
Using iTunes or the Apple Devices App
It's worth noting that Apple is evolving its software ecosystem on Windows. The Apple Devices app is a newer offering that may handle device management, while iTunes might still be used for media library management.11 For the purpose of creating backups, the interface and steps are very similar across these applications. This can sometimes cause confusion for users, so it's important to be aware of which application is installed and primarily used for device interaction on their specific Windows setup.
-
Connect The iPhone: The iPhone should be connected to the Windows PC using a compatible USB cable.
-
Open the Software:
-
iTunes should be opened. If the Apple Devices app is installed, it might launch automatically, or it can be opened directly. It is crucial to ensure that the software being used (iTunes or Apple Devices app) is updated to the latest version.1 For a Windows PC to correctly recognize and communicate with an iPhone, appropriate drivers are necessary. These drivers are typically installed as part of the iTunes or Apple Devices app installation.8 If connection issues occur, outdated or missing drivers can be a common cause on Windows platforms.
-
-
Locate The iPhone: An iPhone button or icon should appear, usually located near the top-left of the iTunes or Apple Devices app window. Clicking this will allow access to the device's settings.1
-
Go to the Summary/General Tab: "Summary" should be clicked (typically in iTunes) or "General" (in the Apple Devices app) to access the backup options.1
-
Choose Backup Settings: Under the "Backups" section, "This computer" must be selected as the backup destination.1
-
Secure The Backup (Crucial): The checkbox labeled "Encrypt local backup" must be selected.1
-
A prompt will appear to create a password. A strong, memorable password should be chosen and stored securely. This password is indispensable for restoring from this encrypted backup, and Apple cannot assist in its recovery if lost.1
-
-
Start the Backup: Clicking the "Back Up Now" button will initiate the backup process.1
-
Monitor Progress: The software will display the backup progress. The iPhone should remain connected until the backup is fully completed.
V. Understanding Your Local Computer Backup: What's Saved & Why Encryption Matters
When an iPhone is backed up to a computer, a significant amount of data is saved. However, not everything is included, and the level of data protection, particularly for sensitive information, depends heavily on whether the backup is encrypted.
What Gets Backed Up to a Computer?
A local computer backup is designed to be quite comprehensive, including almost all of the device's data and settings.4 This typically encompasses:
-
App data (for most apps)
-
Device settings (preferences, configurations)
-
Home screen layout and app organization
-
iMessages, text (SMS), and multimedia (MMS) messages (provided these are not already being synced to iCloud Messages)
-
Photos and videos stored in the Camera Roll (if iCloud Photos is not enabled)
-
Call history
-
Notes (if not being synced to iCloud)
-
And more, such as contact favorites, sound settings, and widget settings.1
What's Not Included in a Computer Backup?
It's important to understand the exceptions to what "almost all data" means to manage expectations effectively. The following types of content are generally not included in a computer backup:
-
Content from the iTunes and App Stores: This includes the apps themselves, as well as music, movies, and TV shows purchased from Apple. This content can typically be re-downloaded from the respective stores.
-
Content Synced from the Mac or PC: Items like imported MP3s or CDs, videos, books, and photos that are already managed and stored on the computer and synced to the iPhone are not re-backed up. The backup process assumes these files already exist on the computer.
-
Data Already Stored and Synced in iCloud: If services like iCloud Photos, iCloud Messages, or iCloud syncing for Contacts, Calendars, and Notes are enabled, that data is stored in iCloud and is generally not duplicated in the local computer backup.
-
Face ID or Touch ID Settings: Biometric authentication data is not included.
-
Apple Pay Information and Settings: Payment details and settings are excluded.
-
Apple Mail Data: Email data from the Mail app is typically not part of the backup.
-
Activity, Health, and Keychain Data (unless encrypted): Sensitive information such as saved passwords for Wi-Fi networks and websites (Keychain), as well as Activity and Health data, are only included if the backup is explicitly encrypted.4 This is a critical distinction.
The Superpower of Encrypted Backups
By default, when an iPhone is backed up to a computer, the backup file is not encrypted.4 Selecting the "Encrypt local backup" option during the setup process fundamentally changes this by locking and encoding the backup file's information.12
Encrypted backups are a game-changer because they include highly sensitive personal data that unencrypted backups omit. For users concerned about having a complete local copy of their most private information, encryption is not merely an optional feature but a necessity. This includes:
-
Saved website and app passwords (Keychain data)
-
Wi-Fi settings (including saved network names and their passwords)
-
Website browsing history
-
Health app data
-
Call history 12
The Password is Key: The password created when enabling backup encryption is paramount. It is impossible to restore data from an encrypted backup without this password. Apple does not have the ability to reset or recover this specific password.12 If the password is forgotten, the primary recourse is to use an alternative backup (like an iCloud backup, if available) or to reset the backup password. Resetting the password allows for the creation of new encrypted backups moving forward but renders all previous encrypted backups inaccessible.12
To clearly illustrate the differences, the following table summarizes what data categories are protected by standard versus encrypted local backups:

VI. Managing iPhone Backups on a Computer: Location, Deletion, and Frequency
Once backups are created, understanding how to locate, manage, and maintain them is important for both data integrity and computer storage management.
Finding Where Backups Are Hiding
iPhone backups are stored in specific default folders on the computer. While direct manipulation of files within these backup folders is strongly discouraged as it can corrupt the backup 15, knowing their location can be useful for verification or advanced troubleshooting.
-
On a Mac:
-
Using Finder (macOS Catalina 10.15 and later): The most straightforward method is to connect the iPhone, open Finder, select the iPhone from the sidebar, navigate to the "General" tab, and click "Manage Backups...". From the list that appears, a specific backup can be right-clicked (or Control-clicked) and "Show in Finder" selected to reveal its location.13
-
Manual Path: To navigate directly, open Finder, click "Go" from the menu bar, choose "Go to Folder...", and enter the path:
~/Library/Application Support/MobileSync/Backup/
. Pressing Enter will open the Backup folder.13 -
Using iTunes (macOS Mojave 10.14 and earlier): Open iTunes, go to iTunes > Preferences from the menu bar, then click the "Devices" tab. Control-click (or right-click) the desired backup from the list and select "Show in Finder".16
-
-
On a Windows PC:
-
The exact path can vary slightly based on whether iTunes or the Apple Devices app was installed from the Microsoft Store or directly from Apple's website.17
-
Common Paths:
-
\Users\(your username)\Apple\MobileSync\Backup\
17 -
\Users\(your username)\AppData\Roaming\Apple Computer\MobileSync\Backup\
(This path can often be accessed by typing%AppData%\Apple Computer\MobileSync\Backup\
into the File Explorer address bar or the Run dialog).13
-
-
Managing via Apple Devices App/iTunes:
-
In the Apple Devices app (or Finder on Mac), after connecting the device and navigating to the General tab, clicking "Manage Backups" will list existing backups. From here, backups can be selected and deleted.13
-
In iTunes, navigating to Edit > Preferences > Devices will display a list of device backups. While this view primarily shows the backups and allows for deletion, it also helps confirm their existence and, for encrypted backups, will show a lock icon.1 Some third-party utilities may offer more advanced browsing capabilities for these backup files.17

Keeping Things Tidy: Deleting Old Backups
Over time, multiple iPhone backups can consume significant disk space on a computer. Regularly deleting old or unnecessary backups can help manage storage.
-
On a Mac (Using Finder): Navigate to Finder > [Your iPhone] > General > Manage Backups.... A list of backups will appear. Select the backup to be removed, then click "Delete." A confirmation will be required.13
-
On a Windows PC (Using Apple Devices App / iTunes):
-
Apple Devices App: Connect the iPhone, select it in the app, go to the General tab, click "Manage Backups...", select the desired backup, and then click "Delete".13
-
iTunes: Go to Edit > Preferences > Devices. Select the backup from the list and click "Delete Backup."
-
Archiving Backups (Mac): A useful feature on Macs (via Finder or older iTunes versions) is the ability to archive a backup. In the "Manage Backups..." window, right-clicking (or Control-clicking) a backup and choosing "Archive" will preserve that specific backup. Archived backups are not overwritten by subsequent backups of the same device.13 This is particularly useful for saving the state of an iPhone before a major iOS update or other significant changes.
How Often Should an iPhone Be Backed Up to a Computer?
There is no universal rule for backup frequency, but regularity is paramount.2 The ideal frequency depends on individual usage patterns and how much data one is willing to risk losing.
-
Consider these guidelines:
-
Monthly: This is a good general recommendation for many users to ensure relatively recent data is preserved.2
-
Weekly: If the iPhone undergoes frequent significant changes—such as numerous new photos, app installations, or critical note-taking—a weekly backup might be more appropriate.6
-
Before Major Events: It is always prudent to perform a backup immediately before installing a major iOS update, prior to taking an iPhone for service or repair, or before migrating data to a new iPhone.6
-
The primary objective is to minimize potential data loss. Users should consider the amount of data they create or modify and how detrimental its loss would be. While frequent backups enhance data safety, they also consume disk space. A balance must be struck, often involving a strategy of regular backups combined with periodic deletion of older, unneeded backup files 13 and potentially archiving critical milestone backups.13
VII. Quick Fixes: When a Computer Backup Goes Wrong
While local iPhone backups are generally reliable, occasional issues can prevent a backup from completing successfully. Understanding common problems and their solutions can save time and frustration.
"Houston, we have a problem..." Common Backup Hiccups
Apple provides official guidance for troubleshooting backup failures.11 Some frequently encountered issues include:
-
1. "Not enough free space is available on this computer."
-
Fix: This message is straightforward. The computer's hard drive lacks sufficient space to store the backup file. Users must free up disk space by deleting unnecessary files or applications.8 Moving other large files to an external drive could also create space. While moving the iPhone backup location itself is an advanced procedure not detailed here, it is technically possible.
-
-
2. "The backup was corrupt or not compatible."
-
Fixes:
-
Ensure the computer's operating system (macOS or Windows) and the backup software (Finder, iTunes, or Apple Devices app) are fully updated.11
-
Verify that the iPhone is running the latest version of iOS.11
-
Attempt to delete the backup that is reported as corrupt (using the "Manage Backups" feature) and then try creating a new backup.
-
It is possible that a previous backup file has indeed become corrupted and is unusable.11
-
-
-
3. "An error occurred" (generic error message).
-
Fixes:
-
Restart both the iPhone and the computer. This simple step can resolve many temporary glitches.8
-
Check the USB cable connection. Try a different USB cable and, if possible, a different USB port on the computer. Faulty or loose cables are a common source of backup problems.8
-
Ensure that the iPhone "Trusts" the connected computer. If prompted on the iPhone, accept the trust request.8
-
For Windows users, temporarily disabling security software (such as antivirus or firewall programs) can help determine if these are interfering with the backup process. Remember to re-enable security software afterward.8
-
Confirm that the latest version of iTunes or the Apple Devices app is installed.11
-
-
-
4. Backup session failed / iPhone refused the request.
-
Fixes: These errors often point to communication issues. The troubleshooting steps are similar to those for generic errors: check all connections, restart devices, and ensure all relevant software is up to date.8
-
General Troubleshooting Steps from Apple
Apple's official troubleshooting advice often follows an iterative process: "Try again after each step".11 This suggests that identifying the exact cause of a backup failure may require trying several simple fixes. Key general steps include:
-
Update the Mac or PC operating system.
-
Update iTunes or the Apple Devices app to the latest version.
-
Disconnect and reconnect the iPhone, ensuring it is properly recognized by the computer.
-
Restart all involved devices (iPhone and computer).
-
(For Windows users) Check for interference from security software.
-
If possible, try creating a backup on a different computer to isolate whether the issue is with the iPhone, the original computer, or the connection.
