    So i have a data entry application, that just reads and write to the database, but it is very important for it to be up 24/7 so if the main server crashes, i need to be able to run that application on a backup server and keep on working, and after the primary comes backup, all the data and changes made on the backup must go to the primary, almost like with mirror.
