备份远程SQL Server数据库

Question

I want to backup my remote SQL Server database onto the local computer.

So far I've tried:

using (SqlConnection defaultSqlConnection = new SqlConnection(Constants.Database_Constants.GetConnectionStringFromProfile(Constants.Profiles.Staging)))
{
    string pathDatabase = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + "\\backup_production_database"+DateTime.UtcNow.ToString("d_MMM_yyyy_HH_mm_ss", CultureInfo.InvariantCulture)+".bak";
    WriteLine("The backup will be stored in " + pathDatabase);

    string backupDb = "BACKUP DATABASE DB_Staging TO DISK = '" + pathDatabase+ "' WITH INIT, COMPRESSION";

    File.Create(pathDatabase);

    using (SqlCommand backupCommand = new SqlCommand(backupDb, defaultSqlConnection))
    {
        defaultSqlConnection.Open();
        backupCommand.ExecuteNonQuery();
    }
}

But I get this error :

Cannot open backup device 'XXXX\\bin\\Debug\\backup_production_database22_Mar_2017_08_04_42.bak'. Operating system error 3(The system cannot find the path specified.). BACKUP DATABASE is terminating abnormally.

I know that I could generate a script using SQL Server Management Studio but it doesn't help me. I want to backup my database in a powershell script automatically without having to go manually into SQL Server Management Studio

You cannot create a directly backup from a remote server to a local disk.
