Which Mac OS X feature simplifies the process of incremental backups?

The correct response is Time Machine, which is specifically designed for creating incremental backups on macOS. Time Machine automatically backs up your entire system, including applications, music, photos, email, documents, and system files. When it runs, Time Machine only saves the changes made since the last backup, making it an efficient way to save disk space and time. This incremental backup approach means that after an initial full backup, subsequent backups only involve the data that has been added or modified, allowing for efficient storage management and easy recovery of files.

In contrast, Spotlight is a search feature that allows you to quickly find files and applications on your Mac but does not play any role in the backup process. Finder is the file management application for macOS, enabling users to browse and manage files, but it also does not facilitate backups. Activity Monitor is a utility for monitoring system performance, including CPU usage, memory, and disk activity, but it does not provide backup functionalities. Thus, Time Machine is the dedicated solution for incremental backups on macOS.
