Hello, every one. I have created some application which will take Backups of a Database in Full and Differential modes in C#.net to the Sql Server 2008 Database, now if i want to make the Restore not entire database, but only the data which is modified on a Particular date. Is it possible to do. I have provided my code samples, can any one help me.

private void BackupDataBaseFull(Server MyServer,Database MyDataBase,string DestinationPath,string Type)
         {
             try

                 backDB.Action = BackupActionType.Database;
                 backDB.Database = MyDataBase.Name;
                 backDB.Devices.AddDevice(DestinationPath, DeviceType.File);
                 backDB.BackupSetName = "Sql Database Backup Full";
                 backDB.BackupSetDescription = "Sql Database Backup - Full Backup";
                 backDB.ExpirationDate = DateTime.Now.AddDays(5);
