C#将远程数据库的SMO备份到本地机器

Microsoft.SqlServer.Management.Smo.FailedOperationException: Backup failed for Server ‘25.98.30.79’. —> Microsoft.SqlServer.Management.Common.ExecutionFailureException: An exception occurred while executing a Transact-SQL statement or batch. —> System.Data.SqlClient.SqlException: Cannot open backup device ‘C:Program FilesState ManagerArchiveCapture20100217152147*product*databases*database**database*.bak’. Operating system error 3(The system cannot find the path specified.).

这似乎是由SQL服务器尝试将此文件写入其本地驱动器引起的.由于安全限制,我无法设置可以放置备份的共享区域.

有人知道如何将这些数据移回机器代码正在被调用？

我的代码如下

private string Name;
    private string Server;
    private string dbName;
    private string user;
    private string password;

    public Boolean performCapture(String archiveDir)
    {
        String destination = archiveDir + "" + Name;
        if (!System.IO.Directory.Exists(destination))
        {
            System.IO.Directory.CreateDirectory(destination);
        }

        Server sqlServer = connect();
        if (sqlServer != null)
        {
            DatabaseCollection dbc = sqlServer.Databases;
            if (dbc.Contains(dbName))
            {
                Backup bkpDatabase = new Backup();
                bkpDatabase.Action = BackupActionType.Database;
                bkpDatabase.Database = dbName;
                BackupDeviceItem bkpDevice = new BackupDeviceItem(destination + "" + dbName + ".bak",DeviceType.File);

                bkpDatabase.Devices.Add(bkpDevice);
                bkpDatabase.Incremental = false;
                bkpDatabase.Initialize = true;
                // Perform the backup
                bkpDatabase.SqlBackup(sqlServer);

                if (System.IO.File.Exists(destination + "" + dbName + ".bak"))
                {
                    return true;
                }
                else
                {
                    return false;
                }
            }
            else
            {
                return false;
            }
        }
        else
        {
            return false;
        }
    }
