+<!-- This document describes the concept of `VolumeSnapshotClass` in Kubernetes. Familiarity
+with [volume snapshots](/docs/concepts/storage/volume-snapshots/) and
+[storage classes](/docs/concepts/storage/storage-classes) is suggested. -->
+
+
+本文档描述了 Kubernetes 中 `VolumeSnapshotClass` 的概念。 建议熟悉[卷快照（Volume Snapshots）](/docs/concepts/storage/volume-snapshots/)和[存储类（Storage Class）](/docs/concepts/storage/storage-classes)。

+
+<!-- ## Introduction
+
+Just like `StorageClass` provides a way for administrators to describe the "classes"
+of storage they offer when provisioning a volume, `VolumeSnapshotClass` provides a
+way to describe the "classes" of storage when provisioning a volume snapshot. -->
+
+## 介绍
+
+就像 `StorageClass` 为管理员提供了一种在配置卷时描述存储“类”的方法，`VolumeSnapshotClass` 提供了一种在配置卷快照时描述存储“类”的方法。
+
+<!-- ## The VolumeSnapshotClass Resource
+
+Each `VolumeSnapshotClass` contains the fields `snapshotter` and `parameters`,
+which are used when a `VolumeSnapshot` belonging to the class needs to be
+dynamically provisioned.
+
+The name of a `VolumeSnapshotClass` object is significant, and is how users can
+request a particular class. Administrators set the name and other parameters
+of a class when first creating `VolumeSnapshotClass` objects, and the objects cannot
+be updated once they are created.
+
+Administrators can specify a default `VolumeSnapshotClass` just for VolumeSnapshots
+that don't request any particular class to bind to.
+ -->
+
+## VolumeSnapshotClass 资源
+
+每个 `VolumeSnapshotClass` 都包含 `snapshotter` 和 `parameters` 字段，当需要动态配置属于该类的 `VolumeSnapshot` 时使用。
+
+`VolumeSnapshotClass` 对象的名称很重要，是用户可以请求特定类的方式。
+管理员在首次创建 `VolumeSnapshotClass` 对象时设置类的名称和其他参数，对象一旦创建就无法更新。
+
+管理员可以为不请求任何特定类绑定的 VolumeSnapshots 指定默认的 `VolumeSnapshotClass`。
+
+
+```yaml
+apiVersion: snapshot.storage.k8s.io/v1alpha1
+kind: VolumeSnapshotClass
+metadata:
+  name: csi-hostpath-snapclass
+snapshotter: csi-hostpath
+parameters:
+```
+<!-- 
+### Snapshotter
+
+Volume snapshot classes have a snapshotter that determines what CSI volume plugin is
+used for provisioning VolumeSnapshots. This field must be specified.
+ -->
+ 
+### 快照生成器（Snapshotter）
+
+卷快照类具有一个快照生成器，用于确定配置 VolumeSnapshot 的 CSI 卷插件。 必须指定此字段。
+
+<!-- ## Parameters
+
+Volume snapshot classes have parameters that describe volume snapshots belonging to
+the volume snapshot class. Different parameters may be accepted depending on the
+`snapshotter`. -->
+
+## 参数
+
+卷快照类具有描述属于卷快照类的卷快照参数。 可根据 `snapshotter` 接受不同的参数。
