管理增强型复制

概览

本页面介绍如何在双区域存储桶上使用增强型复制功能。

所需的角色

为了获得使用增强型复制所需的权限，请让您的管理员为您授予存储桶的 Storage Admin (roles/storage.admin) IAM 角色。

此预定义角色可提供使用增强型复制所需的权限。如需查看所需的确切权限，请展开所需权限部分：

所需权限

• storage.buckets.get
• storage.buckets.update
• storage.buckets.list
  • 仅当您计划使用 Google Cloud 控制台执行本页面上的任务时，才需要此权限。

您也可以使用自定义角色或其他预定义角色来获取这些权限。

如需了解如何授予存储桶的角色，请参阅将 IAM 与存储桶搭配使用。

设置增强型复制

如需在现有存储桶上启用或停用增强型复制，请按照以下说明操作：

控制台

1. 在 Google Cloud 控制台中，进入 Cloud Storage 存储桶页面。
   

   进入“存储桶”

2. 在存储桶列表中，点击所需存储桶的名称。

3. 点击配置标签页。

4. 在复制行中，点击 修改。

   随即显示的窗口表示您要启用增强型复制还是停用增强型复制。

5. 点击保存以确认新设置。

命令行

将 gcloud storage buckets update 命令与 --rpo 标志结合使用：

gcloud storage buckets update gs://BUCKET_NAME --rpo=STATE

其中：

• BUCKET_NAME 是相关存储桶的名称，例如 my-bucket。

• STATE 为 ASYNC_TURBO（用于启用增强型复制）或 DEFAULT（用于停用增强型复制）。

如果成功，响应将如下所示：

Updating gs://my-bucket/...
  Completed 1  

客户端库

C++

如需了解详情，请参阅 Cloud Storage C++ API 参考文档。

如需向 Cloud Storage 进行身份验证，请设置应用默认凭据。 如需了解详情，请参阅为客户端库设置身份验证。

以下示例会在存储桶上启用增强型复制：

namespace gcs = ::google::cloud::storage;
using ::google::cloud::StatusOr;
[](gcs::Client client, std::string const& bucket_name) {
  auto updated = client.PatchBucket(
      bucket_name,
      gcs::BucketMetadataPatchBuilder().SetRpo(gcs::RpoAsyncTurbo()));
  if (!updated) throw std::move(updated).status();

  std::cout << "RPO is set to 'ASYNC_TURBO' for " << updated->name() << "\n";
}

以下示例会在存储桶上启用默认复制：

namespace gcs = ::google::cloud::storage;
using ::google::cloud::StatusOr;
[](gcs::Client client, std::string const& bucket_name) {
  auto updated = client.PatchBucket(
      bucket_name,
      gcs::BucketMetadataPatchBuilder().SetRpo(gcs::RpoDefault()));
  if (!updated) throw std::move(updated).status();

  std::cout << "RPO is set to 'default' for " << updated->name() << "\n";
}

REST API

JSON API

1. 安装并初始化 gcloud CLI，以便为 Authorization 标头生成访问令牌。

2. 创建一个包含以下信息的 JSON 文件：

   {
     "rpo": "STATE"
   }

   其中，STATE 为 ASYNC_TURBO（用于启用 Turbo 复制）或 DEFAULT（用于停用 Turbo 复制）。

3. 使用 cURL 通过 PATCH Bucket 请求调用 JSON API：

   curl -X PATCH --data-binary @JSON_FILE_NAME \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json" \
     "https://storage.googleapis.com/storage/v1/b/BUCKET_NAME?fields=rpo"

   其中：

   • JSON_FILE_NAME 是您在第 2 步中创建的 JSON 文件的路径。
   • BUCKET_NAME 是相关存储桶的名称，例如 my-bucket。

   如果请求成功，则不会返回任何响应。

XML API

此功能无法通过 XML API 进行管理。请改用 JSON API。

检查存储桶的复制状态

如需检查存储桶的恢复点目标 (RPO) 或复制状态，请按照以下说明操作：

控制台

1. 在 Google Cloud 控制台中，进入 Cloud Storage 存储桶页面。
   

   进入“存储桶”

2. 在存储桶列表中，点击要验证的存储桶的名称。

3. 点击配置标签页。

4. 如果该存储桶启用了增强型复制，则复制会设置为增强型。

命令行

使用带有 --format 标志的 gcloud storage buckets describe 命令：

gcloud storage buckets describe gs://BUCKET_NAME --format="default(rpo)"

其中：

• BUCKET_NAME 是相关存储桶的名称，例如 my-bucket。

如果成功，则响应类似如下示例：

rpo: ASYNC_TURBO

客户端库

如需了解详情，请参阅 Cloud Storage C++ API 参考文档。

如需向 Cloud Storage 进行身份验证，请设置应用默认凭据。 如需了解详情，请参阅为客户端库设置身份验证。

namespace gcs = ::google::cloud::storage;

  if (!metadata) throw std::move(metadata).status();

  std::cout << "RPO is " << metadata->rpo() << " for bucket "
            << metadata->name() << "\n";
}

REST API

JSON API

1. 安装并初始化 gcloud CLI，以便为 Authorization 标头生成访问令牌。

2. 使用 cURL，通过 GET Bucket 请求调用 JSON API：

   curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://storage.googleapis.com/storage/v1/b/BUCKET_NAME?fields=rpo"

   其中 BUCKET_NAME 是相关存储桶的名称，例如 my-bucket。

   响应如下例所示：

   {
     "name": "my-bucket",
     "projectNumber": "234...",
     ...
     "rpo": "ASYNC_TURBO"
   }

   请注意 rpo 键。值 ASYNC_TURBO 表示已启用增强型复制。DEFAULT 表示已应用默认复制。双区域和多区域存储桶中始终存在 rpo 字段，但单区域存储桶中不存在该字段。

XML API

此功能无法通过 XML API 进行管理。请改用 JSON API。

后续步骤

• 详细了解增强型复制。

• 详细了解增强型复制价格。

• 了解监控存储桶性能的指标，包括复制性能。
• 了解如何使用 Cloud Monitoring 提醒根据指定的指标创建提醒政策并管理与这些政策关联的通知。
