Hi.
I've added a SQL database to my project. It's beside of the exe file in SQL folder.
I was using SQL to LINQ.
Now I wanna get a backup from it with C#.
I'm using following method :

PHP Code:
public static void GetBackUp()
{
    if (!
Directory.Exists(StaticVariables.BackUPFolder))
        
Directory.CreateDirectory(StaticVariables.BackUPFolder);

    
using (RezaRestaurant.SQL.DataClasses1DataContext dbc = new RezaRestaurant.SQL.DataClasses1DataContext())
    {
        
dbc.ExecuteCommand(@"BACKUP DATABASE " dbc.Mapping.DatabaseName " TO DISK='c:\aaa.bak'");//Exception
    
}

But I've received the below Exception

Name:  BackUP Exception.jpg

Could you please guide me, how I can resolve it ?
