Why each option
NetApp Snapshots are used for data protection by creating read-only, point-in-time copies of volumes that enable recovery from data loss or corruption.
NetApp Snapshots create space-efficient, point-in-time read-only images of a volume using redirect-on-write technology, allowing administrators to restore individual files or entire volumes to a previous state - making them a core data protection mechanism in ONTAP.
Snapshots do not increase performance - they are read-only metadata references to existing blocks and add a small amount of overhead for write operations due to block pointer management.
Snapshots provide no network resiliency functionality - they are a storage-layer feature with no impact on network availability or redundancy.
Storage failover in ONTAP is handled by HA pair takeover and giveback mechanisms, not by Snapshots, which are purely a data recovery tool.
