Manage device backups
A backup includes information about the layout of the Home screen, app data (such as Safari bookmarks and Calendar events), anything you can set in Settings on the device (including restrictions, certificates, and some account types), and contacts. Backups don’t include apps or media that you would normally sync using iTunes in macOS 10.14 and earlier and the Finder in macOS 10.15 and later or that you would store in iCloud or on iCloud Drive. A backup of an unsupervised device is identical to and interchangeable with an iTunes or Finder backup, and can be restored only to an unsupervised device.
