The short answer
For iCloud, go to Settings › [your name] › iCloud › iCloud Backup, turn on Back Up This iPhone and tap Back Up Now. Backups then run automatically when your iPhone is locked, charging and on Wi-Fi. For a computer, connect your iPhone to a Mac (Finder) or a Windows PC (Apple Devices app) and click Back Up Now.
A backup is what saves your photos, messages and settings if your iPhone is lost, broken or replaced. It takes a few minutes to set up and then runs on its own.
You have two options: iCloud, which is automatic and wireless, or a computer, which is free and doesn’t use iCloud storage. Many people use both.
Option 1: Back up to iCloud
- Connect to Wi-Fi.
- Open Settings, tap your name, then iCloud.
- Tap iCloud Backup.
- Turn on Back Up This iPhone.
- Tap Back Up Now and stay on Wi-Fi until it finishes.
After that, your iPhone backs up automatically each day when it’s connected to power, locked and on Wi-Fi.
Check that it worked
On the same iCloud Backup screen, look under Back Up Now for the date and time of your last successful backup.
If you run out of iCloud storage
- Turn off backups for large apps you don’t need in Settings › [your name] › iCloud › Storage › Backups.
- Use iCloud Photos so photos aren’t duplicated in the backup.
- Buy more iCloud storage, or back up to a computer instead.
Option 2: Back up to a computer
On a Mac
- Connect your iPhone with a cable.
- Open Finder and select your iPhone in the sidebar.
- If asked, tap Trust on your iPhone and enter your passcode.
- Under Backups, choose Back up all of the data on your iPhone to this Mac.
- Tick Encrypt local backup if you want to include passwords and Health data, and set a password.
- Click Back Up Now.
On a Windows PC
- Install the Apple Devices app from the Microsoft Store (or use iTunes on older setups).
- Connect your iPhone and tap Trust on the phone.
- Select your iPhone in the app, choose Back up all of the data on your iPhone to this computer, optionally encrypt it, then click Back Up Now.
What a backup doesn’t include
- Data already stored in iCloud, like iCloud Photos, Contacts, Calendars and Notes when they’re synced.
- Content from the App Store and Apple Music, which you can download again.
- Face ID or Touch ID settings.
When to back up manually
- Before an iOS update.
- Before repairs or a battery replacement.
- Before switching to a new iPhone. See how to transfer data to a new iPhone.

The bottom line
Turn on iCloud Backup once and check the “last backup” date every so often. If you’d rather not pay for iCloud storage, back up to your computer regularly and encrypt the backup.
Frequently asked questions
Does an iCloud backup include my photos?
If iCloud Photos is turned on, your photos are already stored in iCloud and aren't included again in the backup. If it's off, photos are part of the iCloud backup.
How much iCloud storage do I need?
Every Apple Account includes 5 GB free, which often isn't enough for a full backup. You can see the size of your backup in Settings › [your name] › iCloud › Storage, and buy more if needed.
Should I encrypt my computer backup?
Yes, if you can. An encrypted computer backup also saves passwords, Health data and other sensitive information. Store the encryption password somewhere safe: you can't restore the backup without it.
