使用 REST API 还原Azure Virtual machines

本文介绍如何使用 REST API 从恢复点还原Azure Virtual Machines或单个磁盘。它涵盖了选择恢复点、触发还原作业以及执行跨区域还原。

先决条件

使用Azure Backup完成Azure VM 备份后，可以从同一备份副本还原整个 VM、磁盘或文件。执行任何还原操作时，首先必须确定相关的恢复点。

为Azure VM 还原选择恢复点

可以使用列出恢复点 REST API 列出备份项的可用恢复点。这是一个简单的 GET 操作，包含所有相关值。

GET https://management.chinacloudapi.cn/Subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupFabrics/{fabricName}/protectionContainers/{containerName}/protectedItems/{protectedItemName}/recoveryPoints?api-version=2019-05-13

{containerName} 和 {protectedItemName} 是在此处构造的。 {fabricName} 为 Azure。

GET URI 包含所有必需的参数。无需额外提供请求正文。

响应

名称	类型	说明
200 正常	RecoveryPointResourceList	OK

示例响应

提交 GET URI 后，将返回 200 (OK) 响应。

    },
......

给定响应中的 {name} 字段标识了恢复点。

触发 Azure VM 的还原操作

选择相关的还原点后，继续触发还原操作。

备份项目上的所有还原操作都使用相同的 POST API 执行。只有请求正文随还原方案而变化。

重要

后面提及有关各种还原选项及其依赖项的所有详细信息。请在继续触发这些操作之前查看。

触发还原操作是 POST 请求。详细了解“触发还原”REST API。

POST https://management.chinacloudapi.cn/Subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupFabrics/{fabricName}/protectionContainers/{containerName}/protectedItems/{protectedItemName}/recoveryPoints/{recoveryPointId}/restore?api-version=2019-05-13

{containerName} 和 {protectedItemName} 是在此构造的。 {fabricName}为“Azure”，{recoveryPointId}是{name}所述的恢复点的字段。

获取恢复点后，需要为相关还原方案构造请求正文。以下部分概述了每个方案的请求正文:

还原磁盘
替换磁盘
还原为新虚拟机

恢复响应

触发任何还原操作是一个异步操作。这意味着，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（正常）。

名称	类型	说明
202 已接受		已接受

示例响应

提交用于触发还原磁盘的 POST URI 后，初始响应为 202（已接受），其中包含位置标头或 Azure-async-header。

  }
}

由于还原作业是长时间运行的作业，因此应按照使用 REST API 文档中“监控作业”的说明，对其进行跟踪。

还原磁盘

如果需要自定义从备份数据创建 VM，可以将磁盘还原到所选的存储帐户，然后根据要求从这些磁盘创建 VM。存储帐户应与恢复服务保管库位于同一区域，并且不应为区域冗余。磁盘以及备份 VM（“vmconfig.json”）的配置存储在给定的storage帐户中。如here所述，下面提供了还原磁盘的相关请求正文。

创建请求正文

若要从Azure VM 备份触发磁盘还原，以下是请求正文的组件：

名称	类型	说明
属性	IaaSVMRestoreRequest	RestoreRequestResourceProperties

有关请求正文的完整定义列表和其他详细信息，请参阅“触发还原”REST API 一文。

示例请求

以下请求正文定义了触发磁盘还原所需的属性:

{
  "properties": {
    "objectType": "IaasVMRestoreRequest",
    "recoveryPointId": "20982486783671",
    "recoveryType": "RestoreDisks",
    "sourceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Compute/virtualMachines/testVM",
    "storageAccountId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Storage/storageAccounts/testAccount",
    "region": "chinaeast2",
    "createNewCloudService": false,
    "originalStorageAccountOption": false,
    "encryptionDetails": {
      "encryptionEnabled": false
    }
  }
}

有选择地还原磁盘

如果您正在选择性地备份磁盘，则会在恢复点摘要和详细响应中提供当前备份的磁盘列表。还可以有选择地还原磁盘，在此处提供了更多详细信息。若要有选择地还原备份磁盘列表中的磁盘，请从恢复点响应中找到磁盘的 LUN，并将 restoreDiskLunList 属性添加到以上请求正文中，如下所示。

{
    "properties": {
        "objectType": "IaasVMRestoreRequest",
        "recoveryPointId": "20982486783671",
        "recoveryType": "RestoreDisks",
        "sourceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Compute/virtualMachines/testVM",
        "storageAccountId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Storage/storageAccounts/testAccount",
        "region": "chinaeast2",
        "createNewCloudService": false,
        "originalStorageAccountOption": false,
        "encryptionDetails": {
          "encryptionEnabled": false
        },
        "restoreDiskLunList" : [0]
    }
}

跟踪响应的方式如此处所述，并且长时间运行的作业完成后，备份的虚拟机（“VMConfig.json”）的磁盘和配置将显示在指定的存储帐户中。

替换已备份虚拟机中的磁盘

还原磁盘在从恢复点创建磁盘，而替换磁盘则将备份 VM 的当前磁盘替换为恢复点中的磁盘。如here所述，下面提供了用于替换磁盘的相关请求正文。

创建请求正文

若要从Azure VM 备份触发磁盘替换，以下是请求正文的组件。

名称	类型	说明
属性	IaaSVMRestoreRequest	RestoreRequestResourceProperties

有关请求正文的完整定义列表和其他详细信息，请参阅“触发还原”REST API 文档。

示例请求

以下请求正文定义触发磁盘还原所需的属性。

{
    "properties": {
        "objectType": "IaasVMRestoreRequest",
        "recoveryPointId": "20982486783671",
        "recoveryType": "OriginalLocation",
        "sourceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Compute/virtualMachines/testVM",

        "region": "chinaeast2",
        "createNewCloudService": false,
        "originalStorageAccountOption": false,
        "affinityGroup": "",
        "diskEncryptionSetId": null,
        "subnetId": null,
        "targetDomainNameId": null,
        "targetResourceGroupId": null,
        "targetVirtualMachineId": null,
        "virtualNetworkId": null
     }
}

还原为另一个虚拟机

如above所述，以下请求正文定义触发虚拟机还原所需的属性。

{
  "properties": {
          "objectType":  "IaasVMRestoreRequest",
          "recoveryPointId": "348916168024334",
          "recoveryType": "AlternateLocation",
          "sourceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Compute/virtualMachines/testVM",
          "targetVirtualMachineId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/targetRG/providers/Microsoft.Compute/virtualmachines/targetVM",
          "targetResourceGroupId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/targetRG",
          "storageAccountId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Storage/storageAccounts/testingAccount",
          "virtualNetworkId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/targetRG/providers/Microsoft.Network/virtualNetworks/testNet",
          "subnetId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/targetRG/providers/Microsoft.Network/virtualNetworks/testNet/subnets/default",
          "region": "chinaeast2",
          "createNewCloudService": false,
          "originalStorageAccountOption": false,
          "encryptionDetails": {
            "encryptionEnabled": false
          }
     }
 }

应该根据上文所述的还原磁盘的相同方式处理响应。

Azure VM 的跨区域还原

如果在用于保护 VM 的保管库上启用跨区域还原，则会将备份数据复制到次要区域。可使用备份数据来执行还原操作。若要使用 REST API 在次要区域触发还原操作，请执行以下步骤：

选择次要区域中的恢复点

可以使用“列出用于 CRR 的恢复点 REST API”列出次要区域中备份项目的可用恢复点。这是一个包含所有相关值的简单 GET 操作。

GET https://management.chinacloudapi.cn/Subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupFabrics/{fabricName}/protectionContainers/{containerName}/protectedItems/{protectedItemName}/recoveryPoints?api-version=2018-12-20

{containerName} 和 {protectedItemName} 是按此构造的这里。 {fabricName} 为 Azure。

GET URI 包含所有必需的参数。不需要额外的请求正文。

注意事项

要获取次要区域中的恢复点，请使用 API 版本 2018-12-20，如上例所示。

响应

名称	类型	说明
200 正常	RecoveryPointResourceList	OK

示例响应

提交 GET URI 后，将返回 200 (OK) 响应。

上述响应中的 {name} 字段标识了恢复点。

获取访问令牌

若要执行跨区域还原，您需要访问令牌来授权请求访问次要区域中复制的还原点。若要获取访问令牌，请执行以下步骤：

步骤 1：

使用 AAD 属性 API 获取次要区域（以下示例中的 chinaeast2）的 AAD 属性：

GET https://management.chinacloudapi.cn/subscriptions/{subscriptionId}/providers/Microsoft.RecoveryServices/locations/chinaeast2/backupAadProperties?api-version=2018-12-20

响应示例

返回的响应格式如下：

{
  "properties": {
    "tenantId": "00000000-0000-0000-0000-000000000000",
    "audience": "https://RecoveryServices/IaasCoord/aadmgmt/wus",
    "servicePrincipalObjectId": "00000000-0000-0000-0000-000000000000"
  }
}

步骤 2：

使用“获取访问令牌 API”授权您的请求，以访问次要区域中复制的还原点：

POST https://management.chinacloudapi.cn/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupFabrics/{fabricName}/protectionContainers/{containerName}/protectedItems/{protectedItemName}/recoveryPoints/{recoveryPointId}/accessToken?api-version=2018-12-20

对于请求正文，粘贴上一步中 AAD 属性 API 返回的响应内容。

{
  "properties": {
    "tenantId": "00000000-0000-0000-0000-000000000000",
    "audience": "https://RecoveryServices/IaasCoord/aadmgmt/wus",
    "servicePrincipalObjectId": "00000000-0000-0000-0000-000000000000"
  }
}

响应示例

返回的响应格式如下：

}

将磁盘还原到次级区域

使用跨区域还原触发器 API 将某个项还原到次要区域。

POST https://management.chinacloudapi.cn/subscriptions/{subscriptionId}/providers/Microsoft.RecoveryServices/locations/{azureRegion}/backupCrossRegionRestore?api-version=2018-12-20

请求正文应包含两个部分：

crossRegionRestoreAccessDetails：粘贴上一步中执行的 Get Access 令牌 API 请求响应的 properties 块以填充请求正文的此段。
restoreRequest：若要填充请求正文的 restoreRequest 段，需要传递之前获取的恢复点 ID 以及源 VM 的Azure Resource Manager（ARM）ID，以及用作暂存位置的次要区域中storage帐户的详细信息。若要执行磁盘还原，请将 RestoreDisks 指定为还原类型。

下面是将 VM 的磁盘还原到次要区域的示例请求正文：

与主要区域还原操作类似，这是一个异步操作，需要单独跟踪。
