iTunes and iCloud backups each contain a lot of data, and they're broadly similar. Apple describe what is stored in each backup type in their knowledge-based, but they don't cover off the rules that influence what is stored and when.

Status iTunes iCloud
Always stored Documents, data from third-party apps, location history, device settings, voice memos Documents, data from third-party apps, location history, device settings
Only stored if encrypted Health data, Keychain, Screen Time passcode N/A
If iCloud Photo Library disabled Photos & videos Photos & videos
If cloud-based Contacts service not enabled Contacts Contacts
If "Messages in iCloud" not enabled Messages Messages
Never stored Email, Apple Pay data, Face ID and Touch ID settings, iTunes or iCloud Music Library Music, Apple Books Email, Apple Pay data, Face ID and Touch ID settings, iTunes or iCloud Music Library Music, Apple Books

If you are using iTunes backups and your backup is not encrypted, it won't contain Health data or saved passwords (ie. your Apple Keychain and Screen Time passcode). If you are using an encrypted iTunes backup, it will be broadly similar to an iCloud backup in terms of its content.

Gegevens in een iTunes- of iCloud-back-up

  • documenten
  • Gegevens van ingebouwde Apple-apps: Notes, Agenda, Berichten (iMessages, SMS, MMS), Oproepgeschiedenis, Safari-browsergeschiedenis, Foto's, Video's, voicemail
  • Gegevens van apps van derden die deze in de back-up opslaan. In de praktijk is dit de meesten van hen. WhatsApp, Kik, Hike, Viber, WeChat, etc. slaan alle rijke gegevens op in back-ups.
  • Locatiegeschiedenisgegevens
  • Apparaat- en netwerkinstellingen
  • Sleutelhangers, keybags en wachtwoordgegevens
  • Veel forensische gegevens

Merk op dat het mogelijk is om uw back-ups handmatig te configureren om sommige van deze gegevens niet te bevatten.

Gegevens niet opgenomen in een iTunes- of iCloud-back-up

  • E-mailberichten van de standaard Apple Mail-app
  • Je iTunes-muziek en video's
  • De iOS-app-installatiebestanden ( .IPA )
  • Touch ID en Face ID-gegevens

We hebben een handleiding over wat elk van de bestanden in een iTunes-back-up is .

Why might data be missing from an iTunes or iCloud backup?

Choices you make with Apple's services can affect the types of data that are stored in your backups. For example, if you enable iCloud Photo Library, that service will act as the main store of your photos and videos. Yes, they'll be synced on your phone if you use it, but they won't all necessarily be backed up, irrespective of whether you choose "Optimise iPhone Storage" or "Download and Keep Originals".

This seems odd at first, but it makes sense when you think about it: if Apple are storing all of your photos in iCloud Photo Library, would you also want them to store a duplicate of all of your photos in a backup? After all, your iPhone wouldn't be the primary home for that data: the iCloud is. So including them in an iTunes backup would slow down the backup process, and eat up your storage space, and backing them up in the iCloud would essentially mean each of your photos was stored twice.

Enabling following services will mean data isn't always stored in your backups:

  • iCloud Photo Library -- as your photos and videos will be stored in iCloud Photo Library and only synced with your phone when needed.
  • iCloud or Gmail Contacts -- as your contacts will be stored in the cloud and synced with your iPhone when needed.
  • Messages in iCloud -- as older messages may be removed from your iPhone and stored in the iCloud, and thus won't be on your phone to be backed up.

The free version of iPhone Backup Extractor will let you easily examine your backup, if you're concerned that it might be missing data. If you'd like to read more, we've got articles on key files in iTunes backups and where apps stored data in iTunes backups.
