Announcing mylvmbackup 0.5
Employee +0 Vote Up -0Vote Down
Eric Bergen from Proven Scaling (which I had the pleasure to meet in person during the MySQL Conference & Expo in Santa Clara last month) was kind enough to send me a patch for the mylmbackup tool, which justifies a new release:
Attached is a patch file for mylvmbackup that adds the ability to use
lvm version 2 and perform innodb recovery on the snapshot prior to
creating a tar ball. The option is named --innodb-recover.

I've also fixed a bug with default value handling for command line
options. In version 0.4 if a config file was specified default values
in the script were all changed to blank. This means that the config
file had to supply values for every variable instead of just the
values that need

mylvmbackup 0.4 has been released
Employee +0 Vote Up -0Vote Down
I am happy to announce version 0.4 of mylvmbackup, a tool to perform consistent backups of a MySQL server's tables using Linux LVM snapshots.

For this release I'd like to especially thank Robin H. Johnson from the Gentoo project, who contributed another batch of useful changes and informed me that mylvmbackup is now in productive use to perform backups of the MySQL databases that power the project's Bugzilla bug tracking system. I am always glad to read about such use cases - how do you utilize mylvmbackup in your environment?

  • The option handling has been improved. mylvmbackup now starts by using the builtin defaults, followed by the default configuration file (/etc/mylvmbackup.conf, followed by an alternative configuration file (specified via

mylvmbackup 0.3 now released
Employee +0 Vote Up -0Vote Down

I am happy to announce version 0.3 of mylvmbackup, a tool that performs consistent backups of a MySQL server's tables using Linux LVM snapshots.

Special thanks go to Fred Blaise, who contributed the majority of the new features that have been added to this new release:

  • It is now possible to use an external configuration file /etc/mylvmbackup.conf to store the options. This is probably more convenient than having to pass a slew of options on the command line or having to hack the script itself to change the default values. This new feature requires the Config::IniFiles Perl module to be installed, a sample configuration file is included in the package.
  • The logging to the console has

mylvmbackup version 0.2 has been released
Employee +0 Vote Up -0Vote Down

I am happy to announce that version 0.2 of the mylvmbackup tool is now available!

mylvmbackup is a Perl script for quickly performing backups of a MySQL server's databases using the Linux Logical Volume Manager (LVM). It creates a consistent LVM snapshot of the server's data directory which is then backed up without further blocking the server's operation.

After version 0.1 was published in May this year, I did not really get much feedback about it. I had some ideas for improvements (see the TODO file included in the package), but never got around to actually start working on them.

Thanks to Robin H. Johnson from the Gentoo project for contributing a number of new options and

Presenting mylvmbackup 0.1
Employee +0 Vote Up -0Vote Down
With all the recent buzz on Planet MySQL about using LVM to perform "semi-hot" backups of MySQL on Linux, I remembered that we once created such a Perl script for a server project that we worked on in cooperation with a hardware vendor. As this particular backup method was also mentioned and recommended in my talk about MySQL backup and security on Linux and the script hasn't actually been publicly available so far, I offered to take over the ownership and release it under the GPL. The first tarball release (0.1) is now available from   [Read more...]
