使用 Azure 数据保护的 REST API 备份 Azure 磁盘

  • 项目

本文介绍如何通过 REST API 管理 Azure 磁盘的备份。

Azure 磁盘备份提供了一个统包式解决方案，通过自动定期创建快照并使用备份策略在配置的时间段内保留快照，为托管磁盘提供快照生命周期管理。 无需对基础结构投入任何资金，无需编写任何自定义脚本，无需产生任何管理开销，就能管理磁盘快照。 它是一个使用增量快照创建托管磁盘时间点备份的崩溃一致性备份解决方案，并支持每日创建多个备份。 它也是一个无代理解决方案，不会影响生产应用程序的性能。 它支持备份和还原 OS 磁盘与数据磁盘（包括共享磁盘），不管这些磁盘当前是否已附加到正在运行的 Azure 虚拟机。

有关 Azure 磁盘备份区域可用性、支持的方案和限制的详细信息，请参阅支持矩阵。

先决条件

配置备份

所涉关键实体

创建保管库和策略后，需要考虑 3 个关键点来保护 Azure 磁盘。

要保护的磁盘

请注意要保护的磁盘的 ARM ID 和位置。 用作磁盘的标识符。

"/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx/resourcegroups/RG-DiskBackup/providers/Microsoft.Compute/disks/msdiskbackup"

快照资源组

磁盘快照存储在订阅内的资源组中。 作为指导原则，建议创建专用资源组作为 Azure 备份服务使用的快照数据存储。 专用资源组可以限制资源组的访问权限，确保备份数据管理的安全性和便捷性。 请注意要放置磁盘快照的资源组 ARM ID。

"/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourcegroups/snapshot-rg"

备份保管库

备份保管库要求在磁盘上具有启用备份的权限。 保管库的系统分配托管标识用于分配此类权限。

分配权限

你需要通过 RBAC 向保管库（保管库 MSI 表示）、相关磁盘和/或磁盘 RG 分配少量权限。 可以通过 Azure 门户或 CLI 执行上述操作。 若要分配相关权限，请参阅配置托管磁盘备份的先决条件。

准备配置备份的请求

为保管库和磁盘设置相关权限并配置保管库和策略后，即可准备请求配置备份。 下面是为 Azure 磁盘配置备份的请求正文。 Azure 磁盘的 Azure 资源管理器 ID (ARM ID) 及其详细信息在 datasourceinfo 部分中提供，策略信息则位于 policyinfo 部分中，在该处，快照资源组作为其中一个策略参数提供。

{
  "backupInstance": {
    "dataSourceInfo": {
      "datasourceType": "Microsoft.Compute/",
      "objectType": "Datasource",
      "resourceID": "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxx/resourceGroups/RG-DiskBackup/providers/Microsoft.Compute/disks/msdiskbackup",
      "resourceLocation": "westUS",
      "resourceName": "msdiskbackup",
      "resourceType": "Microsoft.Compute/disks",
      "resourceUri": ""
    },
    "policyInfo": {
      "policyId": "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxx/resourceGroups/TestBkpVaultRG/providers/Microsoft.DataProtection/backupVaults/testBkpVault/backupPolicies/DiskBackup-Policy",
      "policyParameters": {
        "dataStoreParametersList": [
          {
            "dataStoreType": "OperationalStore",
            "objectType": "AzureOperationalStoreParameters",
            "resourceGroupId": "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourcegroups/snapshot-rg"
          }
        ]
      }
    },
    "objectType": "BackupInstance"
  }
}

验证配置备份的请求

若要验证配置备份的请求是否能成功，请使用验证备份 API。 可以参考响应来执行所需的先决条件，然后提交备份请求的配置。

验证备份请求是 POST 操作，并且 URI 包含 {subscriptionId}、{vaultName} 和 {vaultresourceGroupName} 参数。

POST https://management.azure.com/Subscriptions/{subscriptionId}/resourceGroups/{vaultresourceGroupname}/providers/Microsoft.DataProtection/backupVaults/{backupVaultName}/validateForBackup?api-version=2021-01-01

例如，此 API 转换为：

POST https://management.azure.com/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxx/resourceGroups/TestBkpVaultRG/providers/Microsoft.DataProtection/backupVaults/testBkpVault/validateForBackup?api-version=2021-01-01

我们之前准备的请求正文将用于提供要保护的 Azure 磁盘的详细信息。

示例请求正文

{
  "backupInstance": {
    "dataSourceInfo": {
      "datasourceType": "Microsoft.Compute/disks",
      "objectType": "Datasource",
      "resourceID": "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxx/resourceGroups/RG-DiskBackup/providers/Microsoft.Compute/disks/msdiskbackup",
      "resourceLocation": "westUS",
      "resourceName": "msdiskbackup",
      "resourceType": "Microsoft.Compute/disks",
      "resourceUri": ""
    },
    "policyInfo": {
      "policyId": "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxx/resourceGroups/TestBkpVaultRG/providers/Microsoft.DataProtection/backupVaults/testBkpVault/backupPolicies/DiskBackup-Policy",
      "policyParameters": {
        "dataStoreParametersList": [
          {
            "dataStoreType": "OperationalStore",
            "objectType": "AzureOperationalStoreParameters",
            "resourceGroupId": "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourcegroups/snapshot-rg"
          }
        ]
      }
    },
    "objectType": "BackupInstance"
  }
}

备份请求验证的响应

备份请求验证是一个异步操作。 因此，此操作会创建另一个需要单独跟踪的操作。

它将返回两个响应：创建另一个操作时为 202（已接受），该操作完成时为 200（已确定）。

名称 类型 说明
202 已接受 该操作将异步完成
200 正常 OperationJobExtendedInfo 已接受
其他状态代码 CloudError 描述操作失败原因的错误响应

配置备份请求

验证请求后，可以将相同内容提交到创建备份实例 API。 备份实例表示一个项，该项受备份保管库中 Azure 备份的数据保护服务保护。 在此处，Azure 磁盘是备份实例，可以使用前面经过验证的同一请求正文，只需添加一点内容。

针对备份实例使用唯一名称。 因此，建议组合使用资源名称和唯一标识符。 例如，在下面的操作中，我们将使用 msdiskbackup-2dc6eb5b-d008-4d68-9e49-7132d99da0ed，并将其标记为备份实例名称。

若要创建或更新备份实例，请使用以下 PUT 操作。

PUT https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.DataProtection/{BkpvaultName}/backupInstances/{UniqueBackupInstanceName}?api-version=2021-01-01

例如，此 API 转换为：

 PUT https://management.azure.com/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxx/resourceGroups/TestBkpVaultRG/providers/Microsoft.DataProtection/backupVaults/testBkpVault/backupInstances/msdiskbackup-2dc6eb5b-d008-4d68-9e49-7132d99da0ed?api-version=2021-01-01

创建配置备份的请求

要创建备份实例，下面是请求正文的组成部分：

名称 类型 说明

配置备份请求示例

我们将使用用于验证备份请求的请求正文，并采用唯一名称，如上所述。

            "resourceGroupId": "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourcegroups/snapshot-rg"
          }
        ]
      }
    },
    "objectType": "BackupInstance"
  }
}

配置备份请求的响应

创建备份实例请求是一个异步操作。 因此，此操作会创建另一个需要单独跟踪的操作。

它返回两种响应：创建备份实例并配置保护时返回 201（已创建），配置完成时返回 200（正常）。

名称 类型 说明
201 Created 备份实例 创建备份实例并配置保护
200 正常 备份实例 已配置保护
其他状态代码 CloudError 描述操作失败原因的错误响应

提交 PUT 请求以创建备份实例后，初始响应是带有 Azure-asyncOperation 标头的 201（已创建）。 请注意，请求正文包含所有备份实例属性。

然后通过简单的 GET 命令使用“Azure-AsyncOperation”标头跟踪生成的操作。

  "endTime": "2021-07-07T17:02:20Z"
}

停止保护并删除数据

若要删除对 Azure 磁盘的保护并删除备份数据，请执行删除操作。

停止保护和删除数据是一种 DELETE 操作。

DELETE https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.DataProtection/backupVaults/{vaultName}/backupInstances/{backupInstanceName}?api-version=2021-01-01

例如，此 API 转换为：

DELETE "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxx/resourceGroups/TestBkpVaultRG/providers/Microsoft.DataProtection/backupVaults/testBkpVault/backupInstances/msdiskbackup-2dc6eb5b-d008-4d68-9e49-7132d99da0ed?api-version=2021-01-01"

针对删除保护的响应

DELETE 操作是一种异步操作。 因此，此操作会创建另一个需要单独跟踪的操作。

它将返回两个响应：创建另一个操作时为 202（已接受），该操作完成时为 200（确定）。

名称 类型 说明
200 正常 删除请求的状态
202 已接受 已接受
删除保护的响应示例

提交 DELETE 请求后，初始响应将为带有 Azure-asyncOperation 标头的 202（已接受）。
