Volume Snapshots

Time updated：2025-12-22 09:26:17

This section explains how to manage volume snapshots and volume snapshot contents.

A volume snapshot defines the storage resources required to save the snapshot data. After a volume snapshot is created, the system saves the snapshot data in the backend storage system. Each snapshot data unit corresponds to a volume snapshot content on the KubeSphere platform.

Note
If you did not specify an external persistent storage system when installing KubeSphere, KubeSphere will use the local storage system of the cluster nodes as the persistent storage system. Typically, the local storage system of cluster nodes does not support the volume snapshot feature. Before creating a volume snapshot, you need to install a storage plugin for the KubeSphere cluster, ensure that the backend storage system supports the volume snapshot feature, and create a Volume Snapshot Class.
