Statement: HyperSnap for File is based on Copy-On-Write. Is this statement True or False?

• A. Cannot Be Determined
• B. Not Applicable
• C. False
• D. True

Answer: (C)

Understanding how snapshots are implemented helps here. HyperSnap for File uses Redirect-on-Write to create and manage file-level snapshots. After a snapshot is taken, any subsequent writes go to new blocks and the metadata is redirected to those blocks, while the original blocks remain as they were at the moment of the snapshot. This provides a consistent point-in-time view without duplicating existing data. Copy-On-Write would copy the original blocks when a write touches them after the snapshot, which adds more data movement and overhead. So, the statement is false because HyperSnap for File relies on Redirect-on-Write rather than Copy-On-Write.
