In an effort to reduce recovery time during hardware failures, a server administrator needs to implement a backup method that will allow for complete OS and service/application recovery as long as…

Incremental backup only captures data changed since the last backup, so it cannot independently restore an OS or applications without first applying a full backup and all subsequent incremental sets.

A bare metal backup records a complete image of the physical disk including the boot sector, OS files, installed services, and application data. During recovery, this image is written directly to new compatible hardware, restoring the system to its exact pre-failure state. No OS reinstallation or application configuration is required, making it the fastest path to full operational recovery after hardware failure.

Snapshots capture a point-in-time state of a volume or VM but are typically tied to the source storage platform and do not inherently provide bootable, hardware-independent recovery.

A full backup copies all selected files and data but does not capture OS boot records and system configuration in a way that allows direct restoration onto bare hardware without a separate OS installation.
