Diary of A Webmaster Part 4 - Backing Up With MySQLDump
MySQL is one of the most popular database management systems for the development of interactive Websites that need to utilize persistent data sources. As with all other popular database management systems, MySQL offers several methods to backup your important data. In this article we’ll look at how to backup your databases using the mysqldump utility that comes with MySQL. We’ll review several examples using mysqldump, including the backup of your database to a file, another server, and even a compressed gzip file. I’ll assume that you have MySQL installed locally on a Windows, Unix or Linux machine, and that you have administrative privileges on that machine.

MySQL Database Performance Tuning Best Practices Video Tutorial » My Digital Life
MySQL is one of the most popular database management system that powers the most dynamically served website, including sites with millions traffic and visitors everyday. Many web pages and web applications or services rely on MySQL to store contents data which will be retrieved and read by web servers to dynamically built the web pages that visitors will read. As each visit will mean that web server is required to access the MySQL database server at least once to assemble, build and serve the page to reader, so the performance of MySQL server is very important and essential to the overall speed of website, especially on the busy and heavy loaded web host. To improve the performance of MySQL databases, optimize, or know how to optimize MySQL is a needed skill. Jay Pipes had given a talk during Google TechTalks in April 28, 2006 on best practices and techniques for performance tuning for MySQL DB server.mysql-log-filter - Project Hosting on Google Code
