Question

我创建了一个控制台应用程序，我用它来Full以及Differential Backups; 下面是功能，现在我正在搜索查询，我可以对Incremental Backup进行查询。

FullBackup：

  Success_backup = Execute_Query_Master_Database("BACKUP DATABASE " + DatabaseName + " TO DISK = '" + Backup_FileName + "' ");
  Success_Alter_DB = Execute_Query_Master_Database("ALTER DATABASE " + DatabaseName + "  SET MULTI_USER ");

差异BAckup：

 Success_backup = Execute_Query_Master_Database("BACKUP DATABASE " + DatabaseName + " TO DISK = '" + Backup_FileName + "' WITH  DIFFERENTIAL  ");
 Success_Alter_DB = Execute_Query_Master_Database("ALTER DATABASE " + DatabaseName + "  SET MULTI_USER ");


    public static  bool Execute_Query_Master_Database(string strQuery)
    {
        SqlConnection Conn = null;
        SqlCommand _command;

        {
            string connectionstring = @"Data Source=" + servername + ";Initial Catalog='master';User Id='" + UserName + "';Password='" + PassWord + "'";
            Conn = new SqlConnection(connectionstring);

            Conn.Open();
            _command = new SqlCommand();
            _command.Connection = Conn;
            _command.CommandType = CommandType.Text;
            _command.CommandText = strQuery;
            _command.CommandTimeout = 0;

            _command.ExecuteNonQuery();

            return true;
        }
        catch (Exception ex)
        {              
            Console.WriteLine("Error occured in Function - Execute_Scaler_Master_Database()");
            Console.WriteLine("Error Message as below : ");
            Console.WriteLine("===========================");
            Console.WriteLine(ex.Message);
            Console.WriteLine();

            return false;
        }
        finally
        {
            _command = null;
            Conn.Close();           
        }
    }

Here是描述SQL Server备份选项的MSDN帖子。我没有看到增量备份的选项，至少使用本机SQL命令。

我建议考虑使用Transaction Log Backups，它实际上会在每种可能情况下覆盖你。

希望我帮忙！

什么是增量备份查询
