使用服务器DB (MySQL)同步大型本地数据库

I need to weekly sync a large (3GB+ / 40+ tables) local MySQL database to a server database. The two databases are exactly the same. The local DB is constantly updated and every week or so the server DB need to be updated with the local data. You can call it 'mirrored DB' or 'master/master' but I'm not sure if this is correct.I need to weekly sync a large (3GB+ / 40+ table
