I need a script that can incrementally transfer all the data from one MySQL database to another. That's my first objective, second is to be able to schedule it. What I am trying to do is create a second (backup) database for my Vbulletin website that will be updated automatically during off-peak hours. This would create a twin database that I could hotswap in times of trouble by changing three values in my VB config file. The key is that it has to be incremental to accommodate a large database and small import thresholds. What I'm looking for is something like the BIGDUMP script but for a DB to DB transaction. This solution could already exist and I wouldn't know. PHP and MySQL are well outside my realm of understanding, so any info you could provide would be greatly appreciated.
