本文介绍如何使用 REST API 从 Azure 备份 创建的还原点还原整个文件共享或特定文件。
先决条件
我们假设你已有要还原的已备份文件共享。 如果没有,请查看如何使用 REST API 备份 Azure 文件 ,以了解如何创建一个文件。
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 为:
"/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
 
为备份的 Azure 文件提取恢复点
若要恢复任何已备份的文件共享或文件,请先选择一个恢复的时间点以执行还原操作。 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:

使用 REST API 恢复完整的共享
使用此还原选项可在原始位置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。

创建请求正文
若要为 Azure 文件存储触发还原,以下是请求正文的组件:
| 名称 | 类型 | 说明 | 
|---|---|---|
| 属性 | Azure文件共享还原请求 | 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:还原备份内容的目标存储帐户中的文件共享。
 - targetFolderPath:文件共享中的用于恢复数据的文件夹。
 
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
若要为 Azure 文件触发恢复,以下是请求主体的组件:
