An administrator is selecting a backup technique that will allow the server OS to be completely restored on new hardware in case of a full server failure. Which of the following backup technologies…

A snapshot backup captures the entire state of a system or volume at a specific point in time, including all OS files, settings, and data, making it suitable for full system restoration on new or different hardware when used with compatible restore tooling.

An image backup performs a sector-by-sector copy of an entire disk, preserving the OS, boot records, and all partitions in a self-contained file that can be written directly to new hardware to achieve a complete bare-metal restore.

Bare-metal backup is not a distinct backup technology but rather a descriptor for the recovery scenario - the actual technologies used to achieve a bare-metal restore are image and snapshot backups.

An incremental backup only captures data changed since the last backup of any type, so it does not contain a complete standalone copy of the OS required for full restoration.

A differential backup only captures data changed since the last full backup, so it cannot independently restore a full server OS without a preceding full backup.
