使用 Rest API 还原 Azure 文件共享

本文介绍如何使用 REST API 从 Azure 备份所创建的还原点来还原整个文件共享或特定文件。

完成本文的学习后,你将了解如何使用 REST API 执行以下操作:

  • 查看已备份 Azure 文件共享的还原点。
  • 还原完整的 Azure 文件共享。
  • 还原单个文件或文件夹。

先决条件

假设你已具有一个已备份的文件共享,并且你想要还原它。 如果你没有此类文件共享,请查看使用 REST API 备份 Azure 文件共享,以了解如何创建一个。

本文将使用以下资源:

  • RecoveryServicesVault:azurefilesvault
  • 资源组:azurefiles
  • 存储帐户:afsaccount
  • 文件共享:azurefiles

提取 ContainerName 和 ProtectedItemName

多数与还原相关的 API 调用都需要传递 {containerName} 和 {protectedItemName} URI 参数的值。 使用 GET backupprotectableitems 操作的响应正文中的 ID 属性检索这些参数的值。 在我们的示例中,要保护的文件共享的 ID 是:

"/Subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/azurefiles/providers/Microsoft.RecoveryServices/vaults/azurefilesvault/backupFabrics/Azure/protectionContainers/storagecontainer;storage;azurefiles;afsaccount/protectableItems/azurefileshare;azurefiles

因此这些值转换为以下内容:

  • {containername} - storagecontainer;storage;azurefiles;afsaccount
  • {protectedItemName} - azurefileshare;azurefiles

提取备份的 Azure 文件共享的恢复点

若要还原任何备份的文件共享或文件,请首先选择一个恢复点以执行还原操作。 可以使用 Recovery Point-List REST API 调用列出备份项的可用恢复点。 这是一个使用所有相关值执行的 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=2019-05-13&$filter={$filter}

将 URI 值设置如下:

  • {fabricName}:Azure
  • {vaultName}:azurefilesvault
  • {containername}:storagecontainer;storage;azurefiles;afsaccount
  • {protectedItemName}:azurefileshare;azurefiles
  • {ResourceGroupName}:azurefiles

GET URI 包含所有必需的参数。 无需另外提供请求正文。

GET https://management.chinacloudapi.cn/Subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/azurefiles/providers/Microsoft.RecoveryServices/vaults/azurefilesvault/backupFabrics/Azure/protectionContainers/StorageContainer;storage;azurefiles;afsaccount/protectedItems/AzureFileShare;azurefiles/recoveryPoints?api-version=2019-05-13

提取恢复点的示例响应

提交 GET URI 后,将返回 200 响应:

上述响应中的 {name} 字段标识了恢复点。

使用 REST API 恢复完整的共享

使用此还原选项在原始或备用位置还原完整的文件共享。 触发还原是 POST 请求,你可以使用触发还原 REST API 执行此操作。

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

值 {containerName} 和 {protectedItemName} 的设置方式如此处,recoveryPointID 是前面所述的恢复点的 {name} 字段。

POST https://management.chinacloudapi.cn/Subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/azurefiles/providers/Microsoft.RecoveryServices/vaults/azurefilesvault/backupFabrics/Azure/protectionContainers/StorageContainer;storage;azurefiles;afsaccount/protectedItems/AzureFileShare%3Bazurefiles/recoveryPoints/932886657837421071/restore?api-version=2019-05-13'

创建请求正文

若要触发对 Azure 文件共享的还原,请求正文要包含以下组成部分:

名称 Type 说明
属性 AzureFileShareRestoreRequest RestoreRequestResource 属性

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

还原到原始位置

用于还原到原始位置的请求正文示例

以下请求正文定义触发 Azure 文件共享还原所需的属性:

{
   "properties":{
      "objectType":"AzureFileShareRestoreRequest",
      "recoveryType":"OriginalLocation",
      "sourceResourceId":"/subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/AzureFiles/providers/Microsoft.Storage/storageAccounts/afsaccount",
      "copyOptions":"Overwrite",
      "restoreRequestType":"FullShareRestore"
}
}

还原到备用位置

为备用位置恢复指定以下参数:

  • targetResourceId:要将备份内容还原到的存储帐户。 目标存储帐户应与保管库位于同一位置。
  • 名称:目标存储帐户中要将备份内容还原到的文件共享。
  • targetFolderPath:文件共享中要将数据还原到的文件夹。

用于还原到备用位置的请求正文示例

以下请求正文将 afsaccount 存储帐户中的 azurefiles 文件共享还原到 afaccount1 存储帐户中的 azurefiles1 文件共享。

{
   "properties":{
      "objectType":"AzureFileShareRestoreRequest",
      "recoveryType":"AlternateLocation",
      "sourceResourceId":"/subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/AzureFiles/providers/Microsoft.Storage/storageAccounts/afsaccount",
      "copyOptions":"Overwrite",
      "restoreRequestType":"FullShareRestore",
      "restoreFileSpecs":[
         {
            "targetFolderPath":"restoredata"
}
],
      "targetDetails":{
         "name":"azurefiles1",
         "targetResourceId":"/subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/AzureFiles/providers/Microsoft.Storage/storageAccounts/afaccount1"
}
}
}

响应

触发还原操作是一个异步操作。 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)。

响应示例

提交用于触发还原的 POST URI 后,初始响应为包含位置标头或 Azure-async-header 的 202 (已接受)。

由于备份作业是长时间运行的操作,因此应该根据使用 REST API 监视作业文档中所述对其进行跟踪。

使用 REST API 执行项级别恢复

可以使用此还原选项来还原原始或备用位置中的单个文件或文件夹。

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

值 {containerName} 和 {protectedItemName} 的设置方式如此处,recoveryPointID 是前面所述的恢复点的 {name} 字段。

POST https://management.chinacloudapi.cn/Subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/azurefiles/providers/Microsoft.RecoveryServices/vaults/azurefilesvault/backupFabrics/Azure/protectionContainers/StorageContainer;storage;azurefiles;afsaccount/protectedItems/AzureFileShare%3Bazurefiles/recoveryPoints/932886657837421071/restore?api-version=2019-05-13'

使用 REST API 创建实现项级别恢复的请求正文

若要触发对 Azure 文件共享的还原,请求正文要包含以下组成部分:

名称 Type 说明
属性 AzureFileShareRestoreRequest RestoreRequestResource 属性

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

使用 REST API 还原到原始位置以执行项级别恢复

以下请求正文用于还原 afsaccount 存储帐户中 azurefiles 文件共享的 Restoretest.txt 文件。

创建请求正文

{
   "properties":{
      "objectType":"AzureFileShareRestoreRequest",
      "copyOptions":"Overwrite",

}
}
}

应该按照上文所述的实现完整共享还原的相同方式处理响应。
