使用 REST API 還原 Azure 檔案記憶體

2025-05-22

本文說明如何使用 REST API，從 Azure 備份所建立的還原點還原整個檔案共用或特定檔案。您也可以使用 Azure 入口網站、 Azure PowerShell、 Azure CLI 來還原 Azure 檔案記憶體。

必要條件

我們假設您已經有想要還原的備份的檔案共用。如果您未這麼做，請查看使用 REST API 備份 Azure 檔案，以瞭解如何建立備份。

本文使用下列資源：

RecoveryServicesVault：azurefilesvault
資源群組：azurefiles
儲存體帳戶：afsaccount
檔案共用：azurefiles

擷取 ContainerName 和 ProtectedItemName

針對大部分的還原相關 API 呼叫，您必須傳遞 {containerName} 和 {protectedItemName} URI 參數的值。請在 GET backupprotectableitems 作業的回應主體中使用 ID 屬性來取得這些參數的值。在我們的範例中，我們想要保護的檔案共享標識符為：

"/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，這些值會轉譯如下：

{containername} - storagecontainer;存儲;azurefiles;afsaccount
{protectedItemName} - azurefileshare;azurefiles

擷取已備份 Azure 檔案的還原點

若要還原任何備份的檔案共享或檔案，請先選取恢復點來執行還原作業。已備份項目的可用復原點可使用復原點清單 REST API 呼叫來列出。這是具有所有相關值的 GET 作業。

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

設定 URI 值，如下所示：

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

GET URI 具備所有必要參數。不需要另外的要求本文。

GET https://management.azure.com/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

擷取復原點的回應範例

一旦提交 GET URI，就會傳回 200 回應：

使用上面回應中的 {name} 欄位可識別復原點。

使用此還原選項，在原始或替代位置還原完整的檔案共用。觸發還原屬於 POST 要求，您可以使用觸發還原 REST API 來執行這項作業。

POST https://management.azure.com/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} 的值會在這裡設定，而 recoveryPointID 是上述復原點的 {name} 欄位。

建立要求本文

若要觸發 Azure 檔案的還原，要求本文中的元件如下：

名稱	類型	描述
屬性	Azure 文件分享還原請求	RestoreRequestResource 属性

如需完整的要求本文定義清單及其他詳細資訊，請參閱觸發還原 REST API 文件。

還原至原始位置

還原至原始位置的要求本文範例

下列請求正文定義觸發 Azure Files 還原所需的屬性：

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

還原至替代位置

指定下列參數以進行替代的位置復原：

targetResourceId：要還原備份內容的目標儲存體帳戶。目標儲存體帳戶必須與保存庫位於相同位置。
name：目標儲存帳戶中用於還原備份內容的檔案共用。
targetFolderPath：檔案共用中用以還原資料的資料夾。

還原至替代位置的要求本文範例

下列要求本文會將 afsaccount 記憶體帳戶中的 azurefiles 檔案共用還原至 afaccount1 儲存器帳戶中的 azurefiles1 檔案共用。

回應

還原作業的觸發屬於非同步作業。此作業會建立另一項需要個別追蹤的作業。其會傳回兩個回應：在建立另一項作業時傳回 202 (已接受)，並在該作業完成時傳回 200 (確定)。

回應範例

一旦提交用於觸發還原的 POST URI，初始回應為 202 (已接受) 以及位置標頭或 Azure-async-header。

由於備份作業是長時間執行的作業，所以應該如使用 REST API 監視作業文件所述進行追蹤。

使用 REST API 進行項目層級的復原

您可以使用此還原選項在原始位置或替代位置中還原個別的檔案或資料夾。

{containerName} 和 {protectedItemName} 的值會在這裡設定，而 recoveryPointID 是上述復原點的 {name} 欄位。
