1. API Description

Domain name for API request: lighthouse.intl.tencentcloudapi.com.

This API is used to roll back the system disk snapshot of the specified instance.

Only rollback to the original system disk is supported.

Only snapshots in `NORMAL` status can be used for rollback. To query the status of a snapshot, you can call the `DescribeSnapshots` API and see the `SnapshotState` field in the response.

When a snapshot is rolled back, the status of the instance must be `STOPPED` or `RUNNING`. You can call the `DescribeInstances` API to query the instance status. Instances in `RUNNING` status will be forcibly shut down before snapshot rollback.

A maximum of 20 requests can be initiated per second for this API.

We recommend you to use API Explorer

Try it

API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.
