Step-by-step explanation:
macOS X uses a powerful and convenient software called Time Machine to automatically backup and restore data. Time Machine is an integral part of the macOS that provides a seamless way to create a backup of the entire system, including your files, applications, system files, and preferences. This backup system is designed to work with external storage devices, such as an external hard drive or a supported network storage device.
Time Machine is known for its ease of use. Once set up, it runs in the background, automatically backing up your system at regular intervals. Users can restore their entire system from a Time Machine backup or recover individual files, which is particularly helpful if a file is accidentally deleted or lost. The interface provides a visual timeline, allowing users to navigate through their backups to find snapshots of their system at a specific point in time.
Other options, such as BackupWizard, RestorePro, and DataGuard, are not part of the macOS ecosystem. Hence, the correct answer to the question is a) Time Machine.
