Which backup type is best for bare-metal restores?

• A. Image-based backup
• B. File-level backup
• C. Cloud-backup only
• D. Local backups only

Answer: (A)

Bare-metal restores require bringing the entire machine back to its exact previous state, including the operating system, boot records, drivers, applications, and data. An image-based backup captures a complete snapshot of a disk or partition at a single point in time, so restoring from it reinstalls the OS, boot sector (MBR/UEFI), partition layout, and every file exactly as it was. This makes the restore process you can boot into a recovery environment and rebuild the system in one step. File-level backups only copy individual files and folders, so they cannot recreate the OS, boot structures, or installed programs without additional steps. Relying on cloud-only or local-only backups doesn’t by itself guarantee a full system restore; what matters is that the backup type preserves the entire system image. An image-based approach, whether stored locally or in the cloud, provides the most reliable path to a true bare-metal restore.
