How to backup iPhone to external hard drive is not a one-click process, but it is not complex either. The iPhone backs up to the computer first, then the backup folder is copied to the external drive.
This guide covers the full process on both Mac and Windows, along with a separate method for backing up photos directly.
1. How to Back Up iPhone to External Hard Drive
The core process is the same on Mac and Windows: create a local backup using Finder or iTunes, find where that backup is stored on the computer, and copy it to the external drive.
A full Finder or Apple Devices backup cannot be created directly onto an external drive through iPhone settings.
However, compatible external drives can connect directly to an iPhone for transferring files, photos, and videos. The computer acts as the intermediary.
2. What You Need Before You Start
Confirm the following before starting to avoid interruptions mid-process.
- A USB cable to connect the iPhone to the computer (Lightning or USB-C depending on the iPhone model).
- Enough free space on the internal drive to hold the backup temporarily. Check the iPhone’s storage usage in Settings, General, iPhone Storage to estimate the backup size.
- An external hard drive with enough space for the backup. The backup may be smaller than the iPhone’s total used storage because some content already synced to iCloud or from a computer is not included in the local backup.
- Finder on Mac (macOS Catalina or later), iTunes on older Macs and Windows PCs, or the Apple Devices app on Windows 11.
- The iPhone passcode, which will be required when connecting to the computer for the first time or after a reset.
- Decide whether to encrypt the backup. If you want the local backup to include Health data, saved passwords, Wi-Fi settings, call history, and other protected information, enable Encrypt local backup and save the password somewhere secure. Apple cannot recover an encrypted backup if you forget that password.
3. Create and Save the Backup on Mac
How to backup iPhone to external hard drive on Mac starts with creating the backup in Finder, then moving it to the drive. Both steps are straightforward once the backup folder location is known.
Back Up Your iPhone With Finder
Connect the iPhone to the Mac with a USB cable. Open Finder from the Dock. The iPhone appears in the Finder sidebar under Locations. Click it.
If prompted on the iPhone to Trust This Computer, tap Trust and enter the passcode. In Finder, click General in the top tab row.
Under Backups, select Back up all of the data on your iPhone to this Mac. Click Back Up Now.
The backup runs and the progress bar in the Finder window shows completion. Wait until the backup finishes before disconnecting.
Locate and Copy the Backup Folder
An easier method is to select the iPhone in Finder, click Manage Backups, right-click the backup, and choose Show in Finder. Apple also confirms the default folder is ~/Library/Application Support/MobileSync/Backup/.
Verify the External Copy
Keep the original computer copy until you have verified the external copy. If you later need to restore from the archived backup, you may need to copy it back to Apple’s normal backup location before Finder recognizes it.

4. Backing Up on Windows
How to backup iPhone to external hard drive Windows follows the same logic: create a local backup, find the folder, copy it to the drive.
Use Apple Devices or iTunes
On a current Windows PC, use the Apple Devices app. If your PC does not have Apple Devices or you are using an older Apple software setup, iTunes may still be used.
Connect the iPhone with a USB cable and trust the computer if prompted. In Apple Devices or iTunes, click the iPhone icon and select Back Up Now under Backups.
Select the iPhone, open General in Apple Devices or Summary in iTunes, enable Encrypt local backup if needed, then click Back Up Now.
Find the Windows Backup Folder
The location depends on which Apple software created the backup. Apple currently recommends:
- Press Windows + R and enter %USERPROFILE% if you use the Apple Devices app or Microsoft Store version of iTunes.
- Enter %AppData% if you use the older traditional desktop version of iTunes.
You can also open Apple Devices > General > Manage Backups, right-click the backup, and choose Show in Explorer, which is usually the easiest method.
Copy the Backup to the External Drive
Connect the external hard drive and copy the backup folder from the Windows backup path to the external drive.
Right-click the backup folder, select Copy, navigate to the external drive in File Explorer, and paste. For large backups, the copy may take several minutes.
After copying, compare the folder size and confirm that the copied backup opens normally on the external drive.
Keep the original until you are confident the copy completed successfully.
5. Should You Redirect Future Backups Automatically?
Finder and Apple Devices do not provide a built-in setting for choosing an external drive as the default local-backup destination.
Advanced users sometimes use symbolic links on Mac or junctions on Windows to redirect the MobileSync folder, but this is not part of Apple’s standard backup workflow and can break if the external drive is disconnected or its path changes.
For most users, the safer approach is to create the backup normally and copy the completed backup folder to the external drive afterward.
6. How to Backup iPhone Photos to an External Hard Drive
Knowing how to backup iPhone photos to external hard drive separately from a full device backup is useful when iCloud Photos is enabled and a full device backup is not needed.
Export Directly From Your iPhone
A compatible external drive can connect directly to an iPhone through USB-C or an appropriate Lightning adapter. Once the drive appears in the Files system:
- Open Photos.
- Select the photos and videos you want to copy.
- Tap Share.
- Choose Export Unmodified Original.
- Select the external drive under Locations.
- Tap Save.
Apple notes that edited photos and videos are exported as their unmodified originals with this method.
Some external hard drives require more power than the iPhone can supply, especially with Lightning models. A powered adapter, hub, or independently powered drive may be necessary.
For direct use with iPhone, Apple says the external drive should have one data partition and use a supported format such as APFS, Mac OS Extended, exFAT, FAT32, or FAT.
Save Photos Using a Mac
Connect the iPhone to the Mac and open Image Capture from the Applications folder.
- Select the iPhone in the sidebar.
- Change the Import To location to the external hard drive. Select all photos and click Import All.
- Select the external drive or a folder on it as the import destination, then import the selected photos.
- Image Capture saves them as individual files directly to that location.
Alternatively, open the Photos app on Mac, import from the iPhone, and then export selected photos to the external drive using File, Export.
Using a Windows PC
Connect the iPhone to the Windows PC. Open File Explorer. The iPhone appears as a portable device.
Navigate to Internal Storage, DCIM, and find the photo folders inside. Copy and paste those folders to the external hard drive. This transfers photos as individual image files without any special software.
Live Photos contain both a still-image component and a short video component. Manual DCIM copying can transfer those files, but it may not preserve the Live Photo pairing as cleanly as Apple’s Photos-based import/export workflow.
If iCloud Photos is enabled with optimized storage, some originals may not be physically stored on the iPhone. Apple says to download the original full-resolution versions before importing them to a Windows PC.
Important: Treat the external-drive copy as an archive. If you need to restore the iPhone later, the simplest approach is usually to copy the backup folder back into Apple’s standard MobileSync backup location, then open Finder or Apple Devices and confirm that it appears under Manage Backups.
7. FAQs
Can I Set an External Hard Drive as the Default Backup Location in iTunes?
Not directly through iTunes settings. iTunes and Apple Devices do not have a built-in option to choose a custom backup location. The redirect is achieved by creating a symbolic link or junction point that makes the default backup folder point to a location on the external drive.
Do I Need to Reformat My External Hard Drive for iPhone Backups?
Not necessarily. If you are simply copying the backup folder, the drive only needs to be writable by your computer and have enough free space. ExFAT can be useful when the drive must work with both Mac and Windows, while APFS or Mac OS Extended are common Mac-only formats. If you plan to connect the drive directly to the iPhone, make sure it uses one of Apple’s supported external-storage formats.
Is a Finder Backup the Same as an iCloud Backup?
They contain similar data but are not identical. A local Finder or Apple Devices backup saves much of the iPhone’s data and settings, but it is not a byte-for-byte copy of everything on the device. Some iCloud-synced content and computer-synced media are excluded, and certain sensitive data requires an encrypted backup.
Can I Back Up My iPhone Directly to a USB Drive Without a Computer?
Partially. An iPhone can read from and export photos to a compatible USB drive using a Lightning to USB adapter or a USB-C hub. However, a full iPhone backup (the type created by Finder or iTunes) cannot be created directly on a USB drive without a computer.
Conclusion
Backing up your iPhone is ultimately about having one more place you can trust when something goes wrong. For how to backup iPhone to external hard drive, keep the process simple: create the backup correctly, verify the copy, and store it safely so your data is there when you actually need it.
