What type of data can be accessed through mobile device backups?

Mobile device backups typically include a variety of user-related data that set the environment for a person's use of their device. One of the key types of information stored in these backups is user preferences and settings. This can encompass a wide array of details such as the arrangement of applications on the home screen, theme choices, notification settings, Wi-Fi passwords, and various app-specific configurations. Retaining this information is crucial as it allows users to restore their device or migrate to a new one while keeping their personalized experience intact.

In contrast, while physical device integrity is focused on the condition of the hardware, and hardware specifications provide information about the technical aspects of the device, neither of these can typically be accessed through backups, as they are more related to the device itself than to user data. Unused application data, while it might sound plausible, generally does not get actively backed up because it does not typically contain user settings or preferences that are essential for the operation of apps. Thus, user preferences and settings stand out as the most relevant and accessible type of data through mobile device backups.
