Apple Certified Support Professional Practice Exam 2025 – Complete Prep Guide

Time Machine, Apple's built-in backup feature for macOS, allows users to select multiple backup disks for their backups. This functionality is particularly useful for those who want redundancy or wish to back up to different locations for added security.

When you select multiple disks, Time Machine manages the backups across these disks. It will use the selected disks in the order they are listed, automatically rotating between them when creating backups. This means that if you have, for example, two backup disks, Time Machine will use the first disk for one backup, then switch to the second disk for the next backup, and so on.

This flexibility ensures that if one disk fails or becomes unavailable, you still have access to your backups from the other disks. The ability to select multiple disks enhances the reliability of backups and provides users with various options to safeguard their data effectively.

In contrast, the other options suggest limitations that do not reflect the capabilities of Time Machine accurately, as users can indeed select more than one backup disk for their backups.
