DevOps Glossary

Kubernetes VolumeSnapshot is a Kubernetes API resource that captures a point-in-time snapshot of a PersistentVolumeClaim, or PVC, for backup, restore, and data cloning workflows. It works with the Container Storage Interface, or CSI, and a compatible storage driver, which creates the actual storage-level snapshot outside the Pod. A VolumeSnapshot is useful for stateful workloads such as databases, queues, and application file stores, but it is not a full backup system by itself; you still need to manage retention, consistency, restore testing, and off-cluster protection as part of your Kubernetes infrastructure management.
