Comprehensive and Detailed Explanation From Exact Extract:

The VolumeSnapshot Kubernetes resource provides metadata about snapshots of Persistent Volumes, including references to the parent volume and snapshot IDs. It represents a snapshot request and maintains information linking it to the source PVC and the actual snapshot data. This resource enables Kubernetes-native management of volume snapshots, allowing users to create, delete, and list snapshots declaratively. Portworx integrates with Kubernetes snapshot APIs and populates VolumeSnapshot resources with detailed information necessary for managing snapshot lifecycle and restoring data. The Kubernetes and Portworx documentation highlight VolumeSnapshot as the primary interface to monitor and interact with snapshot metadata, crucial for backup, restore, and disaster recovery workflows in containerized environments【Pure Storage Portworx Snapshot API Guide†source】.
