How to Backup iPhone
Every way to back up an iPhone — iCloud over Wi-Fi, a Mac using Finder, or a Windows PC using the Apple Devices app or iTunes — with what each method actually saves.
| Step | Details |
|---|---|
| 01 | Open Settings > [your name] > iCloud > iCloud Backup Turn on iCloud Backup if it isn't already, then tap Back Up Now. Keep your iPhone on Wi-Fi and plugged in until the progress bar finishes — it can take a while the first time. |
| 02 | Check you have enough iCloud storage first Free iCloud accounts get 5 GB, which fills up fast with photos and app data. If the backup fails partway through, check Settings > [your name] > iCloud > Manage Account Storage before trying again. |
| 03 | On a Mac, connect your iPhone and open Finder Select your iPhone in the Finder sidebar, click General, choose "Back up all of the data on your iPhone to this Mac," and click Back Up Now. |
| 04 | On Windows, use the Apple Devices app (or iTunes on older systems) Connect your iPhone with a cable, trust the computer when prompted, then click General in Apple Devices (or Summary in iTunes) and click Back Up Now. |
| 05 | Turn on "Encrypt local backup" to save passwords and health data A Mac or Windows backup only includes saved passwords, Health data, and Activity data if you check this box and set a password — otherwise those are skipped even though everything else is backed up. |
Losing photos or messages because you skipped a backup before updating iOS or switching phones is completely avoidable — every method below is already built into your iPhone.
Which method should you use?
| Method | Needs a computer? | Storage limit | Includes passwords & Health data? |
|---|---|---|---|
| iCloud | No, Wi-Fi only | 5 GB free, more if you pay | Yes, automatically |
| Mac (Finder) | Yes | None (uses your Mac's drive) | Only if Encrypt local backup is on |
| Windows (Apple Devices / iTunes) | Yes | None (uses your PC's drive) | Only if Encrypt local backup is on |
Backing up with iCloud
Go to Settings > [your name] > iCloud > iCloud Backup, turn the toggle on if it isn't already, and tap Back Up Now. Your iPhone needs to stay connected to Wi-Fi (and ideally plugged in) until the progress bar finishes — the first backup can take a while depending on how much is on your phone. After that, iCloud backs up automatically overnight whenever your phone is charging, locked, and on Wi-Fi.
Backing up with a Mac (Finder)
Connect your iPhone to your Mac with a cable, then select it in the Finder sidebar. Click General, choose "Back up all of the data on your iPhone to this Mac," and click Back Up Now. If you want your saved passwords and Health/Activity data included, check Encrypt local backup first and set a password — without it, those categories are skipped even though the rest of your data still backs up.
Backing up with Windows
Connect your iPhone with a cable and tap Trust on your phone if prompted. On Windows 11, open the Apple Devices app (available free from the Microsoft Store) and click General; on older Windows versions, use iTunes and click Summary instead — the backup button and options are the same either way. Just like on Mac, check Encrypt local backup if you want passwords and Health data included.
Fixing a stuck or failed backup
Running out of iCloud storage is the single most common reason a backup won't finish — check Settings > [your name] > iCloud > Manage Account Storage to see how much room you have left. For a computer backup, make sure the cable connection isn't loose and that your iPhone doesn't lock or disconnect mid-backup.
