What iCloud Backup Covers

iCloud Backup saves specific data from your iPhone, iPad, or iPod Touch to Apple's servers. It does not back up everything on your device. The backup includes your device settings, app data, messages, photos in the Photos app, notes, reminders, health data, home screen layout, and passwords stored in Keychain. It also backs up your mail account settings, calendar events, and call history.

The backup happens automatically when your device is plugged in, locked, and connected to Wi-Fi — usually overnight. You can also start a backup manually by going to Settings, tapping your name, selecting iCloud, then Device, and choosing Back Up Now. The backup runs in the background and does not interrupt normal use.

Key Takeaways

  • iCloud Backup saves app data, messages, photos in the Photos app, settings, and passwords, but not music, movies, or books you bought from iTunes.
  • Backup happens automatically when your device is plugged in, locked, and on Wi-Fi, or you can start one manually from Settings.
  • You get 5 GB of free iCloud storage, and backups count toward that limit — old backups are deleted when you run out of space.
  • Mail, contacts, and calendar data sync through iCloud but are not part of the backup file itself.
  • Apps themselves are not backed up, but their data and settings are — you reinstall the apps from the App Store when you restore.

What iCloud Backup Does Not Include

Music, movies, TV shows, and books you bought from iTunes or Apple Books are not backed up. These items are tied to your Apple ID and will redownload automatically when you sign in on a new device — you do not need a backup to get them back. The same applies to apps: the apps themselves are not backed up, only their data and settings. When you restore from backup, you reinstall the apps from the App Store, and the backup restores your data into them.

iCloud Photo Library is separate from iCloud Backup. If you use iCloud Photo Library, your photos sync to iCloud but are not part of the backup. If you use the Photos app without iCloud Photo Library turned on, those photos are included in the backup. Health data, home automation settings, and Siri shortcuts are backed up, but not if you have disabled iCloud sync for those specific features in Settings.

How Much Storage You Get and What Happens When You Run Out

Every Apple ID gets 5 GB of free iCloud storage. Your backup counts toward this limit. If you have multiple devices, each device's backup takes space, and old backups are deleted automatically when you exceed your limit. This means a backup from an older device may disappear without warning if you run out of space.

You can buy more storage through iCloud+ plans: 50 GB, 200 GB, or 2 TB. These plans also include other features like iCloud Private Relay and expanded Mail storage. You can check how much storage you are using by going to Settings, tapping your name, selecting iCloud, and choosing Manage Storage. The breakdown shows which backups and services are taking up space.

How to Check Your Backup and Turn It On or Off

To see when your device last backed up, go to Settings, tap your name, select iCloud, then Device, and look at the "Last Backup" date and time. If it says "Never," your backup is not running. To turn on backup, make sure you are signed into iCloud (Settings > [Your Name] > iCloud), then go to Device > iCloud Backup and toggle it on. Your device will back up the next time it meets the conditions: plugged in, locked, and on Wi-Fi.

To turn off backup, toggle iCloud Backup off in the same location. You can also delete a specific backup by going to Settings > [Your Name] > iCloud > Manage Storage, selecting the device, and tapping Delete Backup. This frees up space but means you cannot restore from that backup later.

What Happens When You Restore From an iCloud Backup

When you set up a new device or erase and restore an existing one, you can choose to restore from an iCloud backup. During setup, you sign in with your Apple ID, and the device shows a list of available backups. You select the one you want, and the device downloads your settings, app data, messages, and other backed-up information. This process can take 30 minutes to several hours depending on backup size and internet speed.

Apps are not restored from the backup file — instead, the device automatically downloads them from the App Store using your Apple ID. If an app is no longer available in the App Store, it will not reinstall, but your data for that app remains in the backup and may be recovered if you reinstall the app manually later. During restore, keep your device plugged in and on Wi-Fi until the process finishes.

Backup Versus Sync: Understanding the Difference

Backup and sync are different. A backup is a snapshot of your device taken at one moment in time. Sync is ongoing — changes you make to one device appear on others in real time. iCloud Mail, Contacts, Calendar, Notes, and Reminders sync continuously, not as part of the backup. This means if you delete an email on your iPhone, it disappears from your iPad and Mac when ready, even if you have not backed up since the deletion.

iCloud Photo Library also syncs rather than backs up. If you turn on iCloud Photo Library, new photos appear on all your devices automatically. If you delete a photo, it disappears from all devices. This is different from the Photos app backup, which saves a snapshot of your photos at the time of backup. Understanding this distinction matters if you rely on backups to recover deleted data — synced data cannot be recovered from a backup if it has already been deleted across all devices.

Frequently Asked Questions

Does iCloud Backup save my text messages and iMessages?

Yes. Text messages and iMessages are included in iCloud Backup. When you restore from backup, they reappear on your new device. However, message history is only backed up if you have iCloud Backup turned on at the time the messages are sent — older messages sent before you enabled backup are not included.

Will my photos be backed up if I do not use iCloud Photo Library?

Yes, but only the photos in your Photos app at the time of backup. If you use iCloud Photo Library instead, your photos sync continuously rather than being backed up as a snapshot. The two systems work differently — with Photo Library, photos are always current across devices, but without it, you rely on the backup to preserve them.

What if my backup is older than a few days?

Your device should back up automatically every night if it is plugged in, locked, and on Wi-Fi. If your backup is old, check that Wi-Fi is working, your device is actually locking at night, and iCloud Backup is turned on in Settings. You can also start a manual backup by going to Settings > [Your Name] > iCloud > Device > Back Up Now.

Can I back up to iCloud and also use a computer backup?

Yes. You can use both iCloud Backup and a computer backup through a Mac or Windows PC. They are separate and do not interfere with each other. Having both gives you two recovery options if something goes wrong, though each backup takes storage space.

If I delete my iCloud backup, can I get it back?

No. Once you delete a backup from iCloud, it is gone permanently. You cannot recover it. If you think you might need it, do not delete it. A new backup will be created the next time your device backs up automatically.
