MySQL Enterprise Incremental Backup simplified

MySQL Enterprise Backup (MEB) has the capability to make real incremental (differential and cumulative?) backups. The actual releases are quite cool and you should really look at it...

Unfortunately the original MySQL documentation is much too complicated for my simple mind. So I did some testing and simplified it a bit for our customers...

MySQL provides some great enterprise features beside the MySQL Server. The ones we are asked the most at customers are:

MySQL table Point-in-Time-Recovery from mysqldump backup

Sometimes we face the situation where we have a full MySQL database backup done with mysqldump and then we have to restore and recover just one single table out of our huge mysqldump file.
Further our mysqldump backup was taken hours ago so we want to recover all the changes on that table since our backup was taken up to the end.

In this blog article we cover all the steps needed to achieve this goal for MySQL and MariaDB.

Backup Manager for MySQL, MariaDB and Percona Server (mysql_bman)

About

The MySQL Backup Manager (mysql_bman) is a wrapper script for standard MySQL backup tools. The Problem with MySQL backup tools is, that they have many options and thus are overcomplicated and errors are easy made.

mysql_bman has the intention to make backups for MySQL easier and technically correct. This means it should per default not allow non-consistent backups or complain if some functions or parameters are used in the wrong way to guarantee proper backups.

MySQL Environment MyEnv 1.0.4 has been released

FromDual has the pleasure to announce the release of the new version 1.0.4 of its popular MySQL, MariaDB and Percona Server multi-instance environment MyEnv.

Backup is for sissies! Let's have a look what we can do when we are not a sissy...
