Suggested answer: A

Explanation:

A snapshot is a point-in-time image of a system's state that can be created while the system is running, without interrupting operations. Snapshots can be used to restore the entire system to the exact state at the time of the snapshot. They are commonly used in virtualized environments and allow administrators to roll back to a previous state if needed.

Snapshot (Answer A): Captures the entire system's state and can be taken without downtime.

Archive (Option B): Refers to long-term storage, not necessarily something that supports live backups.

Open file (Option C): Refers to a method that handles open files during backup but doesn't provide full system restoration capabilities.

Differential (Option D): Backs up only the data changed since the last full backup but still requires a full backup for complete system restoration.
