使用 ARM 範本在 Azure 中備份虛擬機器

Azure 備份會備份內部部署機器與應用程式，以及 Azure VM。 本文說明如何使用 Azure Resource Manager 範本 (ARM 範本) 和 Azure PowerShell 來備份 Azure VM。 本快速入門著重於部署 ARM 範本來建立「復原服務」保存庫的程序。 如需開發 ARM 範本的詳細資訊，請參閱 Azure Resource Manager 文件和範本參考。

Azure Resource Manager 範本是一個 JavaScript 物件標記法 (JSON) 檔案，會定義專案的基礎結構和設定。 範本使用宣告式語法。 您可以描述預期的部署，而不需要撰寫程式設計命令順序來建立部署。

復原服務保存庫是一個邏輯容器，可儲存受保護資源 (例如 Azure VM) 的備份資料。 當備份作業執行時，它會在復原服務保存庫內建立復原點。 然後您可以使用其中一個復原點，將資料還原到指定的時間點。 此外，您可以使用 Azure PowerShell、Azure CLI 或在 Azure 入口網站中備份 VM。

如果您的環境符合必要條件，而且您很熟悉 ARM 範本，請選取 [部署至 Azure] 按鈕。 範本會在 Azure 入口網站中開啟。

範本中定義的資源為：

• Microsoft.Storage/storageAccounts
• Microsoft.Network/publicIPAddresses
• Microsoft.Network/networkSecurityGroups
• Microsoft.Network/virtualNetworks
• Microsoft.Network/networkInterfaces
• Microsoft.Compute/virtualMachines
• Microsoft.RecoveryServices/vaults
• Microsoft.RecoveryServices/vaults/backupFabrics/protectionContainers/protectedItems

部署範本

若要部署範本，請選取 [試試看] 以開啟 Azure Cloud Shell，然後將下列 PowerShell 指令碼貼到 Shell 視窗中。 若要貼上程式碼，請以滑鼠右鍵按一下 Shell 視窗，然後選取 [貼上]。

$projectName = Read-Host -Prompt "Enter a project name (limited to eight characters) that is used to generate Azure resource names"
$location = Read-Host -Prompt "Enter the location (for example, centralus)"
$adminUsername = Read-Host -Prompt "Enter the administrator username for the virtual machine"
$adminPassword = Read-Host -Prompt "Enter the administrator password for the virtual machine" -AsSecureString
$dnsPrefix = Read-Host -Prompt "Enter the unique DNS Name for the Public IP used to access the virtual machine"

$resourceGroupName = "${projectName}rg"
$templateUri = "https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/quickstarts/microsoft.recoveryservices/recovery-services-create-vm-and-configure-backup/azuredeploy.json"

New-AzResourceGroup -Name $resourceGroupName -Location $location
New-AzResourceGroupDeployment -ResourceGroupName $resourceGroupName -TemplateUri $templateUri -projectName $projectName -adminUsername $adminUsername -adminPassword $adminPassword -dnsLabelPrefix $dnsPrefix

在本快速入門中，您會使用 Azure PowerShell 來部署 ARM 範本。 您也可以使用 Azure 入口網站、Azure CLI 和 REST API 來部署範本。

驗證部署

開始備份作業

此範本會建立 VM，並在 VM 上啟用備份。 部署範本之後，您需要啟動備份作業。 如需詳細資訊，請參閱啟動備份作業。

監視備份作業

若要監視備份作業，請參閱監視備份作業。

清除資源

如果您不再需要備份 VM，便可加以清除。

• 如果您想要嘗試還原 VM，請略過清除程序。
• 如果您使用現有的 VM，可以略過最後的 Remove-AzResourceGroup Cmdlet，讓資源群組和 VM 留在原處。

停用保護，移除還原點和保存庫。 然後，刪除資源群組和相關聯的 VM 資源，如下所示：

Disable-AzRecoveryServicesBackupProtection -Item $item -RemoveRecoveryPoints
$vault = Get-AzRecoveryServicesVault -Name "myRecoveryServicesVault"
Remove-AzRecoveryServicesVault -Vault $vault
Remove-AzResourceGroup -Name "myResourceGroup"

下一步

在本快速入門中，您已建立復原服務保存庫、啟用 VM 的保護功能，並建立初始復原點。

• 了解如何在 Azure 入口網站中備份 VM。
• 了解如何快速還原的 VM
• 了解如何建立 ARM 範本。
