A user wants to back up a device's OS and data. Which of the following is the best way to accomplish this task?

An incremental backup only saves changes since the last full or incremental backup, requiring the full backup and all subsequent incremental backups for a full restore, and it typically focuses on data, not the OS.

A system image is a complete snapshot of an entire drive, including the operating system, installed applications, system settings, and all user data. This allows for a full bare-metal recovery in case of catastrophic system failure, restoring the device to the exact state it was in when the image was created.

A system restore point primarily saves system files and registry settings to revert the OS to an earlier state, but it does not back up user data or create a full OS image for bare-metal recovery.

A differential backup saves all changes since the last full backup, requiring only the full backup and the latest differential backup for a restore, but it also typically focuses on data rather than a complete OS image.
