使用 REST API 还原Azure Files

本文介绍如何使用 REST API 从由 Azure Backup 创建的还原点还原整个文件共享或特定文件。 还可以使用 Azure portal、Azure PowerShell、Azure CLI 还原 Azure Files。

若要了解 Azure Files支持的备份和还原方案、区域可用性和限制，请参阅 support matrix。 有关常见问题，请参阅 常见问题。

先决条件

我们假设你已有要还原的已备份文件共享。 如果您没有，请查看Backup Azure Files using REST API以了解如何创建。

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

获取 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，这些值被转换为以下内容：

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

获取已备份 Azure Files 的恢复点

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：

上述响应中的 {name} 字段标识了恢复点。

使用 REST API 进行完整共享恢复

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。

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

若要为 Azure 文件服务触发恢复操作，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 Files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：备份内容还原到的存储账户。 目标存储帐户必须与保管库位于同一位置。
  • name：目标存储帐户中用于存放还原备份内容的文件共享。
  • 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 azurefiles 文件共享从 afsaccount 存储帐户还原到 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

还原操作的触发是异步操作。 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 202（已接受），其中包含位置标头或 Azure-async-header。

由于备份作业属于长时间运行的操作，因此应根据 使用 REST API 文档进行监控作业的说明对其进行跟踪。

使用 REST API 执行项目级恢复

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 Files”触发还原，请求正文包含以下组件：

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。

使用 REST API 还原到原始位置以执行项级别恢复

以下请求正文用于在afsaccount 存储帐户的azurefiles 文件共享中还原Restoretest.txt文件。

创建请求正文

{
   "properties":{
      "objectType":"AzureFileShareRestoreRequest",
      "copyOptions":"Overwrite",
      "recoveryType":"OriginalLocation",
      "restoreFileSpecs":[
         {
            "fileSpecType":"File",
            "path":"RestoreTest.txt",
            "targetFolderPath":null
}
],
      "restoreRequestType":"ItemLevelRestore",
      "sourceResourceId":"/subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/azurefiles/providers/Microsoft.storage/storageAccounts/afsaccount",
      "targetDetails":null
}
}

使用 REST API 将数据还原到备用位置以进行项目级别的恢复

以下请求正文用于将 afsaccount 存储帐户中 azurefiles 文件共享的 Restoretest.txt 文件还原到 afaccount1 存储帐户中 azurefiles1 文件共享的 restoredata 文件夹。

创建请求正文

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

应该按照如上文所解释的完整共享还原的相同方式处理响应。

后续步骤

使用 Azure portal、Azure PowerShell、Azure CLI、REST API 管理Azure Files备份。
