How to Backup Your iPhone (iCloud or Computer)
The easiest way to back up an iPhone is iCloud Backup — go to Settings → [your name] → iCloud → iCloud Backup and turn it on; it backs up automatically every night when your phone is charging and on Wi-Fi. For a local backup with no storage limits, back up to a computer instead. Here’s everything you need to know.
iCloud vs. computer backup
| iCloud | Computer (Mac/Windows) | |
|---|---|---|
| Wireless | Yes | No (USB or Wi-Fi) |
| Automatic | Yes (nightly) | Manual (or Wi-Fi sync) |
| Storage | Free 5 GB (paid beyond) | Your computer’s disk |
| Best for | Set-and-forget | Full backups, no fees |
Method 1: iCloud Backup (wireless, automatic)
- Go to Settings → [your name] → iCloud → iCloud Backup.
- Toggle Back Up This iPhone on.
- Tap Back Up Now to do it immediately.
After that, it backs up automatically each night when your iPhone is connected to power, on Wi-Fi, and locked.
Storage note: the free 5 GB iCloud tier is often too small for a full backup. You can upgrade (50 GB is ~$0.99/mo) or choose which apps to include.
Method 2: Back up to a Mac
- Connect your iPhone to the Mac with a cable.
- Open Finder (macOS Catalina or later) and select your iPhone in the sidebar.
- Under Backups, choose Back up all of the data on your iPhone to this Mac.
- Click Back Up Now.
Tick Encrypt local backup to include saved passwords and Health data — otherwise those aren’t backed up.
Method 3: Back up to a Windows PC
- Install Apple Devices (or iTunes on older systems) from the Microsoft Store.
- Connect the iPhone and click Trust.
- In the app, select your iPhone → Back Up Now.
What gets backed up
An iCloud or computer backup includes almost everything: photos, contacts, messages, app data, settings, and your home-screen layout. It does not include:
- Content already synced to iCloud (iCloud Photos, Mail, Contacts — these live in iCloud separately).
- Apple Pay information.
- Face ID / Touch ID data.
- Content re-downloadable from iTunes/App Store.
How to restore from a backup
- On a new iPhone: during setup, choose Restore from iCloud Backup or Restore from Mac/PC.
- On your current iPhone: Settings → General → Transfer or Reset iPhone → Erase All Content and Settings, then restore during setup.
How often should you back up?
- iCloud: nightly, automatically — set it and forget it.
- Computer: manually, before a big iOS update or selling the phone.
For moving just your photos (not a full backup), see how to transfer photos from iPhone to computer.
How to check your last backup
To confirm your backup is actually working:
- iCloud: Settings → [your name] → iCloud → iCloud Backup shows the date and time of your last successful backup.
- Mac: In Finder, select your iPhone — the “Latest backup” date appears under Backups.
- Windows: Apple Devices shows the last backup date on the Summary screen.
If the last backup is weeks old, tap Back Up Now to catch up. Before a backup, you may want to clear cache and free up space so it runs faster.
Troubleshooting
| Problem | Fix |
|---|---|
| Backup not completing | Free up iCloud storage, or stay on Wi-Fi + power + locked |
| “Not enough iCloud storage” | Upgrade to 50 GB, or exclude large apps from the backup |
| Backup takes forever | First backup is always slow; do it overnight |
| Photos missing from backup | If using iCloud Photos, they’re stored separately — not in the backup |
FAQ
How do I back up my iPhone to iCloud?
Settings → [your name] → iCloud → iCloud Backup → toggle on → Back Up Now. It then backs up automatically each night.
How much iCloud storage do I need?
The free 5 GB is often too small. A typical backup needs 10–50 GB, so the 50 GB plan (~$0.99/mo) covers most people.
How do I back up my iPhone without iCloud?
Back up to a computer — Finder on a Mac, or Apple Devices/iTunes on Windows. See Methods 2–3.
Does an iPhone backup include photos?
Yes, unless you use iCloud Photos (which stores them separately in iCloud). A backup includes whatever isn’t already synced to iCloud.
How do I restore my iPhone from a backup?
During setup on a new phone, choose Restore from iCloud Backup or Restore from Mac/PC. On the same phone, erase it first via Settings → General → Transfer or Reset iPhone.
Why is my iCloud backup not completing?
Usually not enough storage, or not on Wi-Fi/power. Check you have free iCloud space and are on Wi-Fi with the phone plugged in and locked.
Should I encrypt my backup?
Yes, if you back up to a computer — encryption is the only way to include saved passwords and Health data. Just don’t forget the encryption password.
How long does an iPhone backup take?
The first iCloud backup can take hours (all data). Subsequent backups are incremental and much faster — usually minutes.
Can I back up my iPhone to a Windows PC without iTunes?
Yes — on modern Windows, use the Apple Devices app (from the Microsoft Store) instead of the older iTunes. The process is the same: connect, trust, and click Back Up Now.
How do I know if my iPhone is backed up?
Check Settings → [your name] → iCloud → iCloud Backup — it shows the last successful backup’s date and time. If it’s stale, tap Back Up Now.
Does backing up to iCloud use a lot of data?
The first backup uploads everything, so it uses the most data. After that, only changes are uploaded, so daily backups are small. Back up on Wi-Fi to avoid mobile data charges.
