How to back up an iPhone to an external hard drive on Windows

By Adrián Lengyel, who built SaveMyRoll · Facts about other products checked on 11 November 2026

Short answer: connect the drive, open SaveMyRoll, choose a folder on the external drive and start. It checks free space first, sorts by date taken, and verifies every file, so you know when it is safe to free up the phone.

  1. Prepare the drive. NTFS or exFAT, with enough free space for your library (Settings → General → iPhone Storage → Photos shows its size).
  2. Connect the iPhone with its cable, unlock it and tap Trust.
  3. Choose a folder on the external drive in SaveMyRoll. It shows how many files are new and whether they fit.
  4. Start the backup. If the drive fills up or is unplugged, SaveMyRoll stops at once and tells you; everything saved so far stays verified.
  5. Read the report. Only when it says “Everything is safe” is every file confirmed.
  6. Next month, choose the same folder: only new photos and videos are copied.

Questions

Can I back up iPhone photos directly to an external drive on Windows?

Yes. Apple’s own iPhone backups go to the C: drive by default, but a photo backup tool such as SaveMyRoll can write straight to any folder on an external drive.

Which drive format should I use?

NTFS or exFAT. Avoid FAT32 for videos: it cannot store files larger than 4 GB, and long 4K videos often are.

Is it safe to delete photos from the iPhone afterwards?

Only after the backup is verified. SaveMyRoll’s report says “Everything is safe” only when every file was read back from the drive and matched the original. Ideally keep a second copy too.

Try SaveMyRoll on your own iPhone. The first 100 files are free, with every feature, no account and no time limit.
