In cloud storage, snapshots are best used for which scenario?

• A. Long-term archival storage.
• B. Clone a volume for testing.
• C. Quick rollback to a point in time or cloning a volume.
• D. Encrypting data.

Answer: (C)

Snapshots capture the exact state of a storage volume at a specific moment, making it possible to restore that moment quickly if something goes wrong. They also let you create a new volume from the snapshot, giving you an instant clone for testing or development without touching the original. That combination—fast rollback to a point in time and easy cloning—is what makes snapshots especially useful.

For long-term archival storage, you’d typically use backups or cheaper, offline storage rather than snapshots, which are built for speed and frequent reuse. Encryption is a separate protection layer and isn’t the primary purpose of a snapshot, even though you can snapshot encrypted volumes.
