The role of data stored in MySQL database in today’s world is already known - it powers business and mission critical apps. Protecting this data is of utmost important to any enterprise. Before you actually have a backup in place, that are some very important things to think about the backup implementation. Like for instance, how soon would you want your data recovered after a user or system error? This article provides an indepth analysis about the basics of what needs to be considered while planning a Backup and Recovery solution for your MySQL database.

A MySQL network storage engine for MogileFS.

After writing the MySQL Storage Engine for Amazon S3, and having heavily dug into the storage engine for MemCacheD, it can't really be that hard.

Would it be useful?

Ok, so the MySQL Camp II officially starts in 8 hours and 9 minutes. If you are in New York, it behooves you to attend.

MySQL Camp II is sponsored by Polytechnic Institute, Logic Works, Too Many Connections (free MySQL Camp T-Shirts!), Proven Scaling (Lunch) and Google (Coffee).

I expect a lot of cool discussions and meeting with old and new friends. I will be interested in talking/discussing about:

Optimizing data architecture for InnoDB,
Speeding up MySQL replication,
MySQL disaster recovery,
Setting up QA environments that mimic production
Optimizing MySQL on …

I had a wonderful evening tonight with Jay Pipes, Paul McCullagh, Marc Simony, Ronald Bradford, Tania, Taso, Jeremy (not "the Jeremy" who along with Sheeri was missed) and my wife. We met at The Village Pourhouse for Pre-camp party organized by my good friend Ronald (thanks!).

One line said at the gathering (don't ask why):

"The Naked MySQL DBA: My ISAM is bigger than yours"

That called for a once-in-a-lifetime laughter. It was just so funny.

Scale-up vs scale-out - what are they?

Basically, “scaling up” means to add power to your server, or get a bigger server -build it up. “Scaling out” means to add new servers to your configuration - build it out.

Oracle touts both approaches, using RAC on big servers or on “blades”, or a “grid”.

MySQL generally touts scaling out, and most of the big sites using MySQL use “scale-out”. In my experience, and according to Jay Pipe’s excellent blog entry on the subject, that’s partially because MySQL doesn’t scale up as well as it scales out. (Another reason he mentions - that also fits my experience - is that people who pay for Oracle licensing match that by also buying expensive machines to put it on.)

In Oracle, whether you scale up or out, you’ll probably use RAC, which means setting up private interconnects and basically using “shared everything” with your servers. You’re still sort …

I just re-installed my MacOS 10.4 (Tiger) from scratch. However, it's more than just putting in the DVD and doing an upgrade.. This post is more a reminder for myself when I'll have to do it again!

For MySQL you'll need newer versions installed on MacOS 10.4 of the popular GNU tools: automake, autoconf, bison and libtool. Otherwise you'll notice it doesn't really compile. You'll find URLs here below and download the latest versions.
Additionally I needed to install pkgconfig because /usr/local/bin/autoreconf just failed for the ndb-connectors! Don't ask me why, I just found while googling for it..

I did install everything under /usr/local and changed my $PATH in ~/.bash_profile to PATH="/usr/local/bin:$PATH"

Quick "one liner" for shell to check on the version of the build tools:
shell> for p in automake autoconf bison pkg-config; do echo -n "$p: " ; $p --version | head -n1; done; glibtool …

According to recent survey, over 20% of MySQL users plan to migrate a Microsoft Access applications to MySQL over the next 12 months. However there are few documents available that describe best practices for performing such a migration.
This document summarizes discussion from the ?MS Access Migration? session at the 2007 MySQL User Group meeting in California. That session brought together a number of MySQL users with a goal of identifying key success factors for moving MS Access applications to MySQL.

And the surprises are not over. More is coming. Stay …

Zmanda’s MySQL Backup and Recovery Solution is the only comprehensive backup solution that addresses the unique needs of MySQL databases — such as multiple database storage engines. Zmanda Recovery Manager (ZRM) for MySQL now features graphical tools to simplify the process of protecting MySQL data.

This free presentation from experts in open-source backup and recovery of MySQL will demonstrate Zmanda Management Console for ZRM , which is a web based service integrated with Zmanda Network. It provides management and visualization tools for defining all backup activities of a MySQL DBA:

•  what to backup, e.g. all databases or just the selected tables

• where to store the backup images

• when to perform backups, e.g. schedule daily, weekly or monthly full and incremental backups
