I was going through hell getting my databases synced. I have my local development setup that I work on daily. I am in the process of working on about 7 sites. When I tried to export my database and then import it to my remoter server I always received an error. I think that it was my web host not letting me upload.
Database sync was so easy to set up. I added my secret key, it detected the remote server, and then I pushed my development site to my live remote server. Simple, fast.
Days were wasted technical support. All in the past now. My only question for the developer is, "where can I donate?"
