Lesson 4: iOS File Storage Structure Flashcards
key points
The iOS file system contains two volumes.
The system volume contains the operating system and for this reason cannot be completely erased. Only iOS system data can be written to this location.
The user volume contains user data. Information stored on the user volume is encrypted only when the device is protected with a passcode.
All third-party apps exist within an app sandbox to prevent them from accessing or modifying the contents of other apps without permission from the user.
App data is information created and stored by an app during use.
App data might include the high score of a game or the contents of a document.
App data is stored within the app directory and, potentially, backed up by iCloud or another server.
Local app data is removed when an app is deleted. However, data may still exist in iCloud or a third-party server.
Using Shared iPad divides the data differently on an iOS device.
When a student logs in, apps that support cloud storage sync their app data in the background. Other app data is cached locally on the iPad and, if necessary, continues to push to the cloud even after logout.
Shared iPad allows administrators to designate how many users can share an iPad; local storage is then divided to provide space for each user.
Shared iPad is enabled via a mobile device management (MDM) solution. In Jamf Pro, shared iPad is enbaled as part of a PreStage enrollment.
