腾讯云轻量服务器定时创建快照

把下面的实例ID和secretId、secretKey替换就行了，这里是查询快照然后删除快照并新建一个快照。

由于腾讯云一个轻量只能有两个快照，我这里直接删除第二个快照，所以设置定时任务时，设置多久创建一次新快照都行。

// Depends on tencentcloud-sdk-nodejs version 4.0.3 or higher
const tencentcloud = require("tencentcloud-sdk-nodejs");

const LighthouseClient = tencentcloud.lighthouse.v20200324.Client;

const clientConfig = {
  credential: {
    secretId: "更改为账号secretId",
    secretKey: "更改为账号secretKey",
  },
  region: "ap-guangzhou",
  profile: {
    httpProfile: {
      endpoint: "lighthouse.tencentcloudapi.com",
    },
  },
};

const client = new LighthouseClient(clientConfig);

const chakan = {
  "Filters": [
    {
      "Name": "instance-id",
      "Values": [
        "更改为实例id"
      ]
    }
  ]
};

client.DescribeSnapshots(chakan).then(

  (data) => {

    shanchu_id = data.SnapshotSet[1].SnapshotId //数组的第二个

    const shanchu = {
      "SnapshotIds": [
        shanchu_id
      ]
    };

    client.DeleteSnapshots(shanchu).then(
      (data) => {

        console.log('删除一个旧快照成功');
        console.log(data);

        // 创建快照

        const chuangjian = {
          "InstanceId": "更改为实例id"
        };
        client.CreateInstanceSnapshot(chuangjian).then(
          (data) => {
            console.log('创建一个新快照成功');
            console.log(data);
          },
          (err) => {
            console.error("error", err);
          }
        );

      },
      (err) => {

        console.log('删除一个旧快照失败~~~~必须已有两个快照，才能删除第二个快照并创建新快照');
        console.error("error", err);
      }
    );

  },
  (err) => {

    console.log('查询旧快照失败');
    console.error("error", err);
  }
);

这里是查询一个轻量的流量使用情况，然后发邮件通知我。这里除了实例id和密钥要替换外，还要设置smtp信息。
