ApplyInstanceSnapshot

Last updated: 2023-12-04 16:31:52

    1. API Description

    Domain name for API request: lighthouse.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.
