Backups from your computer
A computer backup of your device, which is not the same as a sync, includes almost all of your device’s data and settings. A backup from a computer doesn’t include:
- Content from the iTunes and App Stores, or PDFs downloaded directly to Apple Books
- Content synced from Finder or iTunes, like imported MP3s or CDs, videos, books, and photos
- Data already stored in iCloud, like iCloud Photos, iMessages, and text (SMS) and multimedia (MMS) messages
- Face ID or Touch ID settings
- Apple Pay information and settings
- Apple Mail data
- Activity, Health, and Keychain data (to back up this content, you’ll need to use Encrypted Backup in iTunes.)
Learn how to back up your device using your computer, how to find backups on your Mac or PC, and how to delete backups that you no longer need.
Contact your wireless network provider
If the missing device is an iPhone or an iPad with cellular, report your missing device to your wireless network provider. Ask the network provider to disable your account to prevent calls, texts and data use. And if your device is covered under your wireless network provider plan, file a claim.

Icloud backups
With a Wi-Fi network connection, you can back up your device using iCloud. You don’t need to plug your device into a computer to back up with iCloud.
iCloud backups include nearly all data and settings stored on your device. iCloud backups don’t include:
- Data that’s already stored in iCloud, like Contacts, Calendars, Notes, iCloud Photos, iMessages, Voice Memos, text (SMS) and multimedia (MMS) messages, and Health data
- Data stored in other cloud services, like Gmail and Exchange mail
- Apple Mail data
- Apple Pay information and settings
- Face ID or Touch ID settings
- iCloud Music Library and App Store content (If it’s still available in the iTunes, App, or Apple Books store, you can tap to re-download your already purchased content.)
Learn how to back up your device using iCloud or how to manage iCloud storage and delete backups that you no longer need.
When you use Messages in iCloud, Health data on iOS 12, or Voice Memos, your content is automatically stored in iCloud. If you turn on iCloud Photos, your content is also automatically stored in iCloud.
