Want to back up your iPhone to a flash drive on Windows or Mac? Learn how using AOMEI FoneBackup, iTunes, or Finder – for a full or selective copy.
An iPhone can hold years of photos, messages, contacts, music, and videos. Keeping a separate copy gives you another recovery option if the phone is lost, damaged, or accidentally erased. A portable USB drive can also help when the computer does not have enough free space for another large backup.
You may want to backup iPhone to USB flash drive for several reasons:
The best route depends on your computer. AOMEI FoneBackup can write a backup directly to USB on Windows. iTunes and Finder first create a local device backup, which you then copy to the flash drive. I’ll show you how to use these three tools in detail below.
AOMEI FoneBackup provides both full and selective backups. It lets you choose a connected USB drive as the destination, so you do not need to create the backup on the computer and move it afterward.
Download and install AOMEI FoneBackup on your Windows PC now!
Step 1. Connect the iPhone and flash drive to the Windows PC, then open AOMEI FoneBackup.
Step 2. Choose Phone Backup > Full Backup, and select Get Started.
Step 3. Turn on Backup Encryption if you want to protect the backup with a password.
Step 4. Under Backup Storage Path, browse to the connected flash drive.
Step 5. Click Start Backup and leave both devices connected until the task completes. You can verify the completed task in My Backups.
A selective backup is easier to inspect and can use less storage. Restoring selected items with AOMEI FoneBackup does not require replacing all current data on the target device.
Step 1. Connect the iPhone and flash drive, launch AOMEI FoneBackup, and authorize the iPhone if asked.
Step 2. Go to Phone Backup > Selective Backup > Get Started.
Step 3. Choose the data categories. To backup iPhone photos to flash drive, click the Photos icon and select the desired photos in the Select Files window.
Step 4. Set Backup Storage Path to the flash drive. Then click Start Backup.
Step 5. Open My Backups to confirm that the task finished and to access the restore option later.
iTunes cannot normally create its device backup directly on a flash drive. The practical approach is to back up the iPhone to the computer, locate the backup folder, and copy that complete folder to USB. iTunes backups are not designed for browsing individual files, and restoring one may replace the current content on the iPhone.
Step 1. Install or open the latest available version of iTunes and connect the iPhone.
Step 2. Click the Device icon, open Summary, and select This Computer.
Step 3. Click Back Up Now and wait until iTunes shows that the latest backup is complete.
💡 Note: If you want to save Health and Activity data from your device or Apple Watch, select Encrypt local backup and create a password. You can't recover your backup without this password.
Step 1. Open the applicable Backup location:

Step 2. Identify the required backup by its modified date.
Step 3. Connect the flash drive and copy the entire backup folder to it. Do not alter the files or subfolders.
Step 4. Safely eject the flash drive after the copy completes.
On newer macOS releases, Finder manages local iPhone backups. As with iTunes, create the backup on the Mac first and then copy the intact backup folder to the flash drive.
Step 1. Connect the iPhone to the Mac, unlock it, and tap Trust if prompted.
Step 2. Open Finder and choose the iPhone under Locations.
Step 3. On the General tab, select Back up all of the data on your iPhone to this Mac.
Step 4. Optionally select Encrypt local backup, then click Back Up Now.
Step 1. In Finder, select the iPhone and choose General > Manage Backups.
Step 2. Control-click the required backup and select Show in Finder.
Step 3. Connect the flash drive and copy the entire highlighted backup folder to the USB drive.
Step 4. Wait for the copy to finish, verify the folder exists on the flash drive, and eject the drive safely.
💡 Notes:
1. Can I backup iPhone to flash drive without a computer?
The methods in this guide require a Windows PC or Mac. A direct phone-to-drive workflow depends on the iPhone model, connector, drive format, power requirements, and the type of files being copied; it is not the same as creating a complete restorable device backup.
2. Can I open an iTunes or Finder backup from the flash drive?
Not as a normal collection of photos and messages. Apple device backups use a structured database intended for restoration. Keep the full folder unchanged. If you need accessible files, use a selective backup or export workflow instead.
3. Can I restore an iTunes or Finder backup directly from USB?
Usually, you must copy the intact backup folder back to the computer's standard MobileSync Backup location before iTunes or Finder can detect it. Do not merge folders or rename files inside the backup.
4. Which method is the most flexible?
On Windows, AOMEI FoneBackup is the most flexible option because it supports direct USB destinations and selective data backup. iTunes and Finder are suitable when you want an Apple local device backup and are comfortable copying the complete backup folder afterward.
To backup iPhone to flash drive on Windows with the least manual file handling, use AOMEI FoneBackup and set the USB drive as the destination for a full or selective backup. With iTunes or Finder, first create a local backup and then copy the entire unchanged backup folder to USB. Whichever method you choose, verify the copy before deleting any original data and keep encrypted-backup passwords in a safe place.
Besides iPhone backup, you can also use AOMEI FoneBackup to transfer non-purchased music from iPhone to computer. Try it now to discover more!
