MySQL databases are increasingly used by high volume, high transaction applications
that support businesses running full throttle 24-hours a day, seven days a week.
Backup and recovery operations need to be conducted in such as way that is non-disruptive
to users and applications. The latest release of Zmanda Recovery Manager (ZRM) 2.2 provides
Continuous Data Protection (CDP) as well as instant point-in-time recovery for MySQL.
In this webinar, we will demonstrate the latest ZRM enhancements so that you can use ZRM
to build a robust, flexible, and easy to use backup and recovery solution.

LewisC's An Expert's Guide To Oracle Technology

Do you know which open source feature is the most important? Do you know which open source database rocks and which one sucks? Is MySQL better than Postgres? Is Ingres worth considering? How does Firebird compare? Have you used, or have you considered using, an open source database?

Take a survey. It's only 15 questions so it takes just a few minutes.

I'll post a link where you can get the results once they have been compiled and prepared.

BTW, this isn't my survey. I'm just passing on the link.

Last week I learned that Sun has put its 3 database groups (Java DB, MySQL, PostgreSQL) under Marten Mickos. First off, who knew Sun had such a broad database portfolio???? Second, smart move putting them all under Marten. In speaking with Marten's Java DB team I gave them a small nugget of advice that has served us incredibly well with WebSphere Application Server Community Edition (WAS CE). Simply put win with the strengths of the family, not individual products. I've written about customers wanting choice and flexibility and the challenges of trying to position any product, OSS or not, as... READ MORE

The title of MySQL’s website states that they are the world’s most popular open-source database. This is false; MySQL is not an open-source database. That assertion is a fact, not an opinion.

MySQL is Free Software, licensed under the GNU GPL. People frequently use the two phrases “Free Software” and “Open Source Software” as synonyms, but there are very large, very important differences.

The difference between Free and Open Source

Open Source is much more of a development methodology than a philosophical standpoint. The first thing on the Open Source Initiative’s website is this introduction:

Open source is a development method for software that harnesses the power of distributed peer review and transparency of …

I had an interesting discussion with Marten Mickos at JavaOne last week that I've been meaning to blog about. I was disappointed that MySQL decided to put encryption and compression backup into MySQL Server (GPL license), versus including those features only in MySQL Enterprise (commercial license). Most of you will recall the outrage from "the community" that began when MySQL considered adding these enterprisey features only inside of MySQL Enterprise. I wanted to discuss this situation with Marten. I do not believe that Support and/or Monitoring around an OSS product are viable long term value propositions that will convince users... READ MORE

MySQL is back on Open Source track and that is definitely the best news for all (including community, MySQL and Sun as well). I think that now Sun/MySQL have agreed to the importance of community, it becomes community's responsibility to give them more reasons to believe so. Let's participate like never before.

Kaj, in his post says "...model to be useful for both those who spend money to save time, and those who spend time to save money". This is what Open Source is, isn't it?

All in all, a decision most awaited and …

Update: I’ve been suffering some ungly and stupid bugs today, so I’ve fixed them and released version 0.2. It also includes a new script wp-update-home.

I’ve just published some scripts that help me manage my personal wordpress installations, and publish some plugins I’m working on.

Warning: these are early versions which I use for small tasks. If you find
a bug or have suggestions, contact me at jbernal@warp.es

Ask any DBA what are his top priorities for backup of MySQL. Chances are that hot backup and recovery to a specific point-in-time (or transaction) will be on top of everybody?s list.

The recovery to any point-in-time has been always an ultimate goal for data protection. Traditional backup solutions allow recovering only to a point in time when the last backup took place, e.g. last night. A lot of new data could be created and lost since that last backup. That is why in the last several years many vendors have been working on Continuous Data Protection (CDP).

Storage Networking Industry Association (SNIA) defines Continuous Data Protection (CDP) as “a class of mechanisms that continuously capture or track data modifications enabling recovery to previous points in time”.

First up, I want to say, I’m truly impressed with Brazil. One day I will visit this amazing place, and spread the good word of open source with projects that are close to my heart: MySQL, OpenOffice.org, Fedora, and in due time, a lot more. This is a live-blog, from a most interesting talk, at JavaOne 2008. As I wrote on Twitter, “Brazil, simply impresses me. Their use of open source in government, makes me think that the rest of the world has a lot to learn from them”.

Note: these are live notes. It was a great talk, I’d rate it as excellent (and I’m not just saying that because Josh and I work in the same group at Sun). I’ll have to also comment on his thoughts and talk, in due time. MySQL, as an open source project, has a lot to learn.
