## Volume Snapshot and Restore Volume from Snapshot Support
{{< feature-state for_k8s_version="v1.17" state="beta" >}}
{{< feature-state for_k8s_version="v1.20" state="stable" >}}
Volume snapshot feature was added to support CSI Volume Plugins only. For details, see [volume snapshots](/docs/concepts/storage/volume-snapshots/).
To enable support for restoring a volume from a volume snapshot data source, enable the
`VolumeSnapshotDataSource` feature gate on the apiserver and controller-manager.
Volume snapshots only support the out-of-tree CSI volume plugins. For details, see [Volume Snapshots](/docs/concepts/storage/volume-snapshots/).
In-tree volume plugins are deprecated. You can read about the deprecated volume plugins in the [Volume Plugin FAQ] (https://github.com/kubernetes/community/blob/master/sig-storage/volume-plugin-faq.md).
