It s a good practice to use a config file like this    lt  xml version  1 0  encoding  utf-8   gt   lt configuration gt     lt connectionStrings gt       lt add name  MyConnString  connectionString  Data Source  local  Initial Catalog MyDB  Integrated Security SSPI   Timeout 30   gt     lt  connectionStrings gt     lt appSettings gt       lt add key  BackupFolder  value  C  temp    gt     lt  appSettings gt   lt  configuration gt     Your C  code will be something like this      read connectionstring from config file var connectionString   ConfigurationManager ConnectionStrings  MyConnString   ConnectionString       read backup folder from config file   C  temp    var backupFolder   ConfigurationManager AppSettings  BackupFolder     var sqlConStrBuilder   new SqlConnectionStringBuilder connectionString       set backupfilename  you will get something like   C  temp MyDatabase-2013-12-07 bak   var backupFileName   String Format   0  1 - 2  bak        backupFolder  sqlConStrBuilder InitialCatalog       DateTime Now ToString  yyyy-MM-dd      using  var connection   new SqlConnection sqlConStrBuilder ConnectionString         var query   String Format  BACKUP DATABASE  0  TO DISK   1              sqlConStrBuilder InitialCatalog  backupFileName        using  var command   new SqlCommand query  connection                 connection Open            command ExecuteNonQuery
