Question

我想执行将Azure SQL数据库作为DACPAC导出到Blob存储的计划任务。我想知道我可以这样做吗。网络工作？ Powershell脚本？

Answer 1

我们也可以使用WebJob执行此操作。我用Microsoft.Azure.Management.Sql -Pre .Net SDK创建了一个演示版，它对我来说很成功。有关如何部署webjob和创建预定作业的更多信息，请参阅以下文档。

creating-and-deploying-microsoft-azure-webjobs

create-a-scheduled-webjob-using-a-cron-expression

以下是我的详细步骤和示例代码：

<强>先决条件：

在Azure AD中注册应用程序并为其创建服务原则。有关如何注册应用和获取访问令牌的更多详细信息，请参阅document。

<强>步骤：

1.创建C＃控制台应用程序

2.使用Azure AD中的注册表应用程序获取accessToken

public static string GetAccessToken(string tenantId, string clientId, string secretKey)
 {

    var clientCredential = new ClientCredential(clientId, secretKey);
    var context = new AuthenticationContext("https://login.windows.net/" + tenantId);
    var accessToken = context.AcquireTokenAsync("https://management.azure.com/", clientCredential).Result;
    return accessToken.AccessToken;
  }

3.创建Azure sqlManagementClient对象

  SqlManagementClient sqlManagementClient = new SqlManagementClient(new TokenCloudCredentials(subscriptionId, GetAccessToken(tenantId,clientId, secretKey)));

4.使用sqlManagementClient.ImportExport.Export将.dacpac文件导出到azure存储

var export = sqlManagementClient.ImportExport.Export(resourceGroup, azureSqlServer, azureSqlDatabase,   
                    exportRequestParameters)

5。转到应用程序的Bin / Debug路径，并在.zip文件中添加 all 内容。

从Azure门户

从kudu工具

从天蓝色存储中检查备份文件。

SDK信息请参阅Package.config文件。

演示代码：

 static void Main(string[] args)
        {
            var subscriptionId = "Your Subscription Id";
            var clientId = "Your Application Id";
            var tenantId = "tenant Id";
            var secretKey = "secretkey";
            var azureSqlDatabase = "Azure SQL Database Name";
            var resourceGroup = "Resource Group of Azure Sql ";
            var azureSqlServer = "Azure Sql Server";
            var adminLogin = "Azure SQL admin login";
            var adminPassword = "Azure SQL admin password";
            var storageKey = "Azure storage Account Key";
            var baseStorageUri = "Azure storage URi";//with container name endwith "/"
            var backName = azureSqlDatabase + "-" + $"{DateTime.UtcNow:yyyyMMddHHmm}" + ".bacpac";  //back up sql file name
            var backupUrl = baseStorageUri + backName;
            ImportExportOperationStatusResponse exportStatus = new ImportExportOperationStatusResponse();
            try
            {
                ExportRequestParameters exportRequestParameters = new ExportRequestParameters
                {
                    AdministratorLogin = adminLogin,
                    AdministratorLoginPassword = adminPassword,
                    StorageKey = storageKey,
                    StorageKeyType = "StorageAccessKey",
                    StorageUri = new Uri(backupUrl)
                };

                SqlManagementClient sqlManagementClient = new SqlManagementClient(new TokenCloudCredentials(subscriptionId, GetAccessToken(tenantId,clientId, secretKey)));
                var export = sqlManagementClient.ImportExport.Export(resourceGroup, azureSqlServer, azureSqlDatabase,   
                    exportRequestParameters); //do export operation

                while (exportStatus.Status != OperationStatus.Succeeded) // until operation successed
                {
                    Thread.Sleep(1000 * 60);
                    exportStatus = sqlManagementClient.ImportExport.GetImportExportOperationStatus(export.OperationStatusLink);  
                }

               Console.WriteLine($"Export DataBase {azureSqlDatabase} to Storage wxtom2 Succesfully");
            }
            catch (Exception)
            {

             //todo

            }
        }
