# CreateSnapshot

## 1. API Description

This API (CreateSnapshot) is used to create a snapshot of the specified disk.

{% hint style="info" %}
**Notes**

* This is an asynchronous API. The request returns immediately after submission, but the operation is not yet complete. You can query the snapshot creation result by calling [`DescribeSnapshots`](/api-reference/compute/zec/disk-snapshot/describesnapshots.md). If the snapshot status changes from `CREATING` to `AVAILABLE`, the creation was successful. The snapshot cannot be deleted during the creation process.
* Whether the disk supports creating snapshots can be determined by the `SnapshotAbility` field, which can be queried via the [`DescribeDisks`](/api-reference/compute/zec/disk/describedisks.md) API.
* The disk must be in **In Use** or **Available** state.
* See the product usage limits for the maximum number of snapshots that can be created.
  {% endhint %}
