"Back up your iPhone" sounds like one job. It is actually two, and without a computer they need two different tools.
The first job is the device: your apps and their data, your settings, your Home Screen, your messages. Lose the phone and this is what lets a new one feel like yours within an hour.
The second job is your photo library: the photos, videos, and documents that exist nowhere else. Lose these and there is no reinstalling them.
Without a Mac or PC, Apple gives you exactly one way to back up the device, iCloud Backup, and it has a blind spot precisely where the second job lives. This guide covers both halves, and where VaultDrive fits.
Can you back up an iPhone without a computer?
Yes, in two parts:
- iCloud Backup for the device — apps, settings, messages. Nothing to install.
- A USB drive for your photos, videos, and files, copied straight from the phone with no computer involved.
One limitation to be clear about up front: there is no way to make a complete local device backup without a computer. A full backup of apps, settings, and messages to your own storage still requires a Mac or PC running Finder, iTunes, or the Apple Devices app. Without one, the whole-device backup has to go to iCloud.
What you can keep locally, without a computer, is the part that matters most — your photo library.
What does iCloud Backup actually include?
Most people assume "everything." It does not, and the gaps are the point of this article.
iCloud Backup includes most of the data and settings stored on the device: app data, device settings, your Home Screen and app layout, iMessage and SMS messages, purchase history, and ringtones.
It does not include data already stored in iCloud. That covers Contacts, Calendars, Notes, Reminders, and anything else set to sync to iCloud, plus:
- Your photos, when iCloud Photos is on. Apple treats the library as already in iCloud and leaves it out.
- Your messages, when Messages in iCloud is on, for the same reason.
It also excludes things like Apple Pay details and Face ID or Touch ID settings, and apps themselves are downloaded again from the App Store instead of being stored in the backup.
That photo rule creates a trap. With iCloud Photos on, your photo library is not in your backup — and iCloud Photos is a sync service, so deleting a photo on your phone deletes it from iCloud and every other device too. Both switches are green, and your photos still have exactly one live copy. Backup vs. sync covers why that distinction matters.
With iCloud Photos off, photos are included in the backup — and on any real library they blow straight through the free 5 GB.
Either way, the most irreplaceable part of your phone is the part iCloud Backup handles worst.
How to turn on iCloud Backup
For the device half:
- Open Settings and tap your name at the top.
- Tap iCloud, then iCloud Backup.
- Turn on Back Up This iPhone.
- Tap Back Up Now to make the first backup immediately.
After that, the iPhone backs itself up automatically, typically overnight, when it is connected to power, connected to Wi-Fi, and locked. On models that support it, you can also allow backups over cellular.
Check it worked: the same screen shows the date and time of the last successful backup. If that date is weeks old, something is stopping it — most often, not enough iCloud storage.
The storage question. Apple's free tier is 5 GB, shared across everything in your iCloud account. A device backup without photos is often small enough to fit. With photos included, you will almost certainly need a paid iCloud+ plan, and that cost continues for as long as you want the backup to exist. Taking the photo library out of the equation is the simplest way to keep the device backup small.
Backing up the photo half to a USB drive
This is the part that no longer needs a computer. Since iOS 13, an iPhone can read and write external drives directly.
- iPhone 15 and later have USB-C, so a USB-C flash drive or portable SSD plugs straight in.
- iPhone 14 and earlier need a Lightning to USB adapter.
- Format the drive exFAT. FAT32 cannot store any file over 4 GB, which long 4K and ProRes videos easily exceed.
The full hardware and formatting walkthrough is in how to back up iPhone photos to a USB drive without a computer.
You can do this with the built-in Files app: select photos, tap Share, choose Save to Files. For a small batch, that is fine. For an entire library, it runs into problems quickly — manual selection, no memory of what you already copied, long waits while iOS downloads originals from iCloud when Optimize iPhone Storage is on, and nothing that checks the result. Files app vs VaultDrive goes through those limits in detail.
How VaultDrive solves the photo half
VaultDrive is built for exactly the gap iCloud Backup leaves. It copies your library from the iPhone straight to a USB drive over the cable, with no computer, no account, and nothing uploaded. Here is how it handles each part of the problem.
Your originals aren't on the phone. If Optimize iPhone Storage is on, your phone holds small previews and the real photos live in iCloud. VaultDrive downloads the originals first, over Wi-Fi only by default so a large library doesn't use your cellular data. Anything it can't retrieve is reported as "In iCloud — not on this phone" instead of being silently counted as backed up.
You want everything, not a selection. Back up the whole library, or pick specific albums. No selecting thousands of photos by hand.
Your albums stay organized. On the drive, each album becomes a folder of the same name — an album called Italy 2025 becomes a folder called Italy 2025. Screenshots get their own folder, and documents from the Files app keep their original folder structure.
Full quality, nothing lost. Files are copied byte for byte, with no compression or re-encoding, so HEIC, ProRAW, ProRes, 4K, and Cinematic video arrive exactly as they left. Live Photos stay paired, and each photo keeps its capture date, location, and camera details.
A long backup survives interruptions. On iOS 26 and later, a backup keeps running after you leave the app, and its progress shows in a system Live Activity. If iOS stops it anyway, it resumes where it left off when you return. On earlier iOS versions it pauses shortly after you leave the app and picks up where it stopped when you come back. Either way, nothing already copied is lost, and a single problem file doesn't end the run — it is logged with a reason, and the backup continues.
The copy is checked. After each file, VaultDrive confirms it exists on the drive and its size matches the original, with an optional SHA-256 hash check. A file that fails is marked as failed, not counted as backed up.
Next time takes minutes. With Pro, later backups copy only what's new since the last run.
Your photos stay yours. No account or sign-up, and none of your photos, videos, or files are uploaded — they travel over the cable to the drive and nowhere else.
Core backup is free up to 200 files or 2 GB per run, which is enough to try it on your own library. Pro is a one-time purchase, not a subscription, and removes the limit.
What VaultDrive does not do is back up the device itself — apps, settings, and messages. That is iCloud Backup's job. The two are meant to be used together.
The complete setup
| What | Tool | Where it lives |
|---|---|---|
| Apps, settings, messages | iCloud Backup | Apple's servers |
| Photos, videos, Live Photos | VaultDrive | A USB drive you own |
| Documents from Files | VaultDrive | The same drive |
Set up this way, losing your phone costs you an afternoon of setup rather than your memories. Losing access to your Apple account, or deleting a photo by mistake, no longer takes your library with it. And because the photos are off the phone and out of the iCloud backup, the device backup stays small enough to fit a modest plan.
Why a cloud copy and a drive copy protect you from different things is covered in USB backup vs cloud backup.
A reasonable routine: leave iCloud Backup to run on its own each night, and connect the drive once a month plus after any trip or event.
How do you restore?
The device. When you set up a new or erased iPhone, choose to transfer your apps and data from iCloud Backup and sign in. The phone downloads your settings and app data, and apps reinstall from the App Store.
The photos. This is where plain files pay off. A VaultDrive backup is ordinary files in ordinary folders, so there is nothing proprietary to unpack. Connect the drive, open the Files app, browse to the photos, select them, tap Share, and save the images or videos back to your library. The same folders open on any Mac, PC, or Android phone, with or without the app.
Switching phones? Apple offers Prepare for New iPhone under Settings → General → Transfer or Reset iPhone. It gives you temporary extra iCloud storage — at the time of writing, for up to 21 days — to complete a full backup for the move, even if your usual plan is too small. It's useful for the move, but it doesn't replace a copy you keep.
Frequently Asked Questions
Can you back up an iPhone without a computer?
Yes, in two parts. iCloud Backup backs up the device itself — app data, settings, Home Screen layout, and messages — with no computer involved. Your photo library is best backed up separately, because iCloud Backup skips it whenever iCloud Photos is on. An iPhone can copy its photos, videos, and files straight to a USB drive with an app like VaultDrive, again with no Mac or PC.
Does iCloud Backup include my photos?
Only if iCloud Photos is turned off. When iCloud Photos is on, Apple treats the library as already stored in iCloud and leaves it out of the device backup. That library is synced rather than backed up, so deleting a photo on the phone deletes it from iCloud too. If iCloud Photos is off, photos are included in the backup, but they usually exceed the free 5 GB on their own.
Is there a way to make a full local iPhone backup without a computer?
No. A complete local device backup, including apps, settings, and messages, still requires a Mac or PC using Finder, iTunes, or the Apple Devices app. Without a computer, the whole-device backup has to go to iCloud. What you can keep locally without a computer is the photo library and your files, which you can copy directly to a USB drive.
How much iCloud storage do I need to back up my iPhone?
Apple's free tier is 5 GB, shared with everything else in your iCloud account. A device backup without photos is often small enough to fit. With photos included, or with iCloud Photos turned on, a real library almost always needs a paid iCloud+ plan. Moving the photo library to a USB drive is the main way to keep an iCloud device backup within a smaller plan.
Does VaultDrive back up my whole iPhone?
No. VaultDrive backs up your photos, videos, Live Photos, screenshots, and files from the Files app to a USB drive at original quality. It does not back up apps, app data, settings, or messages; iCloud Backup handles those. The two are designed to be used together, with VaultDrive covering the part iCloud Backup leaves out.
How do I restore photos from a USB drive to my iPhone?
Connect the drive, open the Files app, browse to the photos on the drive, select them, tap Share, and choose to save the images or video. Because a VaultDrive backup is made of ordinary files in ordinary folders, restoring needs no special app, and the same files open on any computer.
The short version
Without a computer, a complete iPhone backup comes in two halves.
iCloud Backup handles the device: apps, settings, and messages. Turn it on and let it run each night.
Your photo library needs its own copy, because iCloud Backup either skips it (when iCloud Photos is on) or can't fit it in 5 GB (when it's off). VaultDrive copies the originals straight to a USB drive — albums kept as folders, full quality, checked file by file, with nothing uploaded — and after the first run it only copies what's new.
Apps can always be downloaded again. Your photos can't — so make sure they exist somewhere you control.
