从未托管在 SQL Server 上的 Windows 应用程序备份 SQL Server DB

Question

有许多示例可以提供 SMO 解决方案来备份 SQL 数据库，我有一个可以使用。

虽然我的场景需要我从连接到网络的计算机上的 Windows 应用程序备份 SQL 数据库。

问题出在服务器名称上...每次我运行以下代码时都会收到错误消息“'ServerName' 的备份失败。”

显然找不到服务器。当我在服务器（以及我的本地机器）上运行代码时，我的课程就会运行。

如何连接到服务器？

我的代码如下：

public void BackupDB(string database, string databasename)
    {

        // Check if file exists - if so delete it...We don't want multiple backups kept.
        if (File.Exists(databasename) == true)
        {
            File.Delete(databasename);
        }

        Server srv = new Server("My SERVER NAME");

        Backup bkpDBFull = new Backup();


        /* Specify whether you want to back up database or files or log */
        bkpDBFull.Action = BackupActionType.Database;

        /* Specify the name of the database to back up */
        bkpDBFull.Database = database;

        /*  backup on the file system */
        bkpDBFull.Devices.AddDevice(databasename, DeviceType.File); 
        bkpDBFull.BackupSetName = "Database Backup";
        bkpDBFull.BackupSetDescription = "Database - Full Backup";

        /* You can specify the expiration date for your backup data
         * after that date backup data would not be relevant */
        //bkpDBFull.ExpirationDate = DateTime.Today.AddDays(10);

        /* You can specify Initialize = false (default) to create a new
         * backup set which will be appended as last backup set on the media. You
         * can specify Initialize = true to make the backup as first set on the
         * medium and to overwrite any other existing backup sets if the all the
         * backup sets have expired and specified backup set name matches with
         * the name on the medium */
        bkpDBFull.Initialize = false;

        /* Wiring up events for progress monitoring */
        progbar1.Value = 0;
        progbar1.Maximum = 100;
        progbar1.Value = 10;
        bkpDBFull.PercentComplete += new PercentCompleteEventHandler(PercentCompleteEventHandler);
        bkpDBFull.PercentCompleteNotification = 10;

        //bkpDBFull.Complete += Backup_Completed;

        /* SqlBackup method starts to take back up
         * You can also use SqlBackupAsync method to perform the backup
         * operation asynchronously */
        try
        {
            bkpDBFull.SqlBackup(srv);
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
            return;
        }

        MessageBox.Show("Backup Complete");

        this.Close();
    }

您需要在您的 SQL 服务器中启用来自其他计算机的连接。此说明将指导您完成整个过程：
