The two ways to back up your iPhone to a computer
You can back up your iPhone to a computer using either iCloud or a direct connection with iTunes or Finder. iCloud backs up automatically over WiFi once you turn it on, while a direct connection lets you control exactly when the backup happens and stores the data on your computer's hard drive instead of in the cloud. Most people use iCloud for convenience, but a direct backup is faster if you have a large amount of data and want to keep everything offline.
The method you choose depends on whether you want automatic backups or prefer to back up manually, and whether you want the backup stored on Apple's servers or on your own computer. Both methods protect your photos, messages, settings, and app data — the difference is where that data lives and how often it updates.
Key Takeaways
- iCloud backs up automatically over WiFi when your iPhone is plugged in and locked, but you pay for storage if you exceed 5 GB.
- A direct backup through Finder (Mac) or iTunes (Windows) stores everything on your computer and requires you to plug in your iPhone manually.
- Both methods encrypt your data, but a direct backup gives you a copy you control entirely on your own device.
- You can use both methods at the same time — iCloud for automatic protection and a direct backup as an extra copy.
How to set up iCloud backups on your iPhone
Open Settings on your iPhone, tap your name at the top, then tap iCloud. Scroll down and tap iCloud Backup. Turn on the toggle next to "iCloud Backup" so it shows blue. Your iPhone will now back up automatically whenever it is plugged in, locked, and connected to WiFi.
iCloud gives you 5 GB of free storage. If your backup is larger than that, you will see a message that your backup could not complete. You can check how much space your backup uses by going back to Settings > [Your Name] > iCloud > Manage Account Storage, then tapping Backups and selecting your iPhone. If you need more space, Apple offers paid plans starting at 50 GB per month. The backup runs in the background and does not interrupt normal use of your phone.
How to back up your iPhone through Finder or iTunes
On a Mac running macOS Catalina or newer, plug your iPhone into your computer with a USB cable. Open Finder, click your iPhone in the sidebar under Locations, then click General. Under Backups, select "Back up all of the important data on your iPhone to this Mac" and click Back Up Now. The backup will take several minutes depending on how much data is on your phone.
On Windows or an older Mac, use iTunes instead. Plug in your iPhone, open iTunes, click the iPhone icon in the top left, then click Back Up Now under the Backups section. iTunes will create a backup file on your computer that contains everything on your phone. You can see where the backup is stored by going to Edit > Preferences > Devices on Windows, or iTunes > Preferences > Devices on Mac.
This type of backup is encrypted by default, which means the data is scrambled and protected. You can also choose to encrypt the backup by checking the box next to "Encrypt iPhone backup" before you click Back Up Now. An encrypted backup protects passwords and health data, but you will need to remember the password you set if you ever restore from it.
What gets backed up and what does not
Both iCloud and direct backups save your photos, videos, messages, contacts, calendars, notes, reminders, health data, app data, and device settings. They also save your home screen layout, wallpaper, and notification preferences. Backups do not include music or movies you bought from iTunes, apps themselves (they are reinstalled from the App Store when you restore), or data from apps that store information only on their own servers.
If you use a service like Spotify or Gmail, those apps back up their own data to their own servers, not to your iPhone backup. Your backup will restore the apps themselves and your login information, but not the content inside them — you will still have your playlists and emails because they live in Spotify and Gmail's systems, not on your phone.
How often to back up and when backups happen automatically
iCloud backups run automatically once per day when your iPhone is plugged in, locked, and on WiFi. You do not need to do anything — the backup happens in the background. If you want to back up right away instead of waiting for the automatic schedule, go to Settings > [Your Name] > iCloud > iCloud Backup and tap Back Up Now.
Direct backups through Finder or iTunes only happen when you plug in your phone and click the backup button yourself. There is no automatic schedule. If you want regular backups without plugging in your phone every time, iCloud is the better choice. If you want to control exactly when backups happen and keep everything on your computer, use direct backups and plug in your phone once a week or once a month depending on how often your data changes.
Checking that your backup is working
For iCloud, go to Settings > [Your Name] > iCloud > iCloud Backup. You will see the date and time of your last backup under "Latest Backup". If the date is recent, your backup is working. If it says "Backup in progress" or shows a date from several days ago, your phone may not have been plugged in and locked on WiFi at the right time.
For direct backups, open Finder (Mac) or iTunes (Windows), plug in your iPhone, and look at the Backups section. You will see the date and time of your most recent backup. If you want to see the actual backup file on your computer, the location varies by operating system — on Mac it is usually in ~/Library/process Support/MobileSync/Backup/, and on Windows it is usually in C:\Users\[Your Username]\AppData\Roaming\Apple Computer\MobileSync\Backup\.
Restoring from a backup if you get a new iPhone or reset yours
When you set up a new iPhone or restore an existing one, you will be asked whether you want to restore from a backup. If you choose to restore from iCloud, sign in with your Apple ID and select which backup you want to use. If you choose to restore from a computer backup, plug your iPhone into the computer where the backup is stored, open Finder or iTunes, select your iPhone, and click Restore Backup.
The restore process copies everything from the backup back onto your phone — your photos, messages, apps, and settings will all return to the way they were when the backup was made. This takes time depending on the size of your backup and your internet speed. Do not unplug your phone during the restore.
Frequently Asked Questions
Can I back up to both iCloud and my computer at the same time?
Yes. You can turn on iCloud Backup and also plug your phone into your computer to create a direct backup. Having both gives you two copies of your data — one in the cloud and one on your computer. This is useful if you want automatic protection through iCloud but also want an offline copy you control.
What happens if I run out of iCloud storage?
Your backup will not complete and you will see a message on your phone. You can delete old backups of other devices you no longer use, delete photos or videos from iCloud Photos to free up space, or pay for a larger iCloud plan. You can also switch to backing up only through your computer instead.
Do I need WiFi to back up to my computer?
No. A direct backup through Finder or iTunes uses the USB cable connection and does not need WiFi. iCloud backups do require WiFi because they send data to Apple's servers over the internet.
Will backing up my iPhone back up my Apple Watch or iPad too?
No. Each device backs up separately. Your iPhone backup contains only iPhone data. If you want to back up your Apple Watch, it backs up through your iPhone automatically when you set up iCloud. Your iPad has its own separate backup that you set up the same way as your iPhone.
How long does a backup take?
iCloud backups usually take 10 to 30 minutes depending on how much data is on your phone and your WiFi speed. Direct backups through Finder or iTunes are usually faster because they use a USB cable — typically 5 to 15 minutes. The first backup takes longer than later ones because it has to copy everything.
