MySQLTuner is a script written in Perl that allows you to review a MySQL installation quickly and make adjustments to increase performance and stability. The current configuration variables and status data is retrieved and presented in a brief format along with some basic performance suggestions.

MySQLTuner supports in this last version ~250 indicators for MySQL/MariaDB/Percona Server.

MySQLTuner is maintained and indicator collect is increasing week after week supporting a lot of configurtion sush as:

Unless you are a MySQL performance tuning expert, it can be enormously challenging and somewhat overwhelming to locate and eliminate MySQL bottlenecks. While many DBAs focus on improving the performance of the queries themselves, this post will focus on the highest-impact non-query items: MySQL Server Performance and OS Performance for MySQL.

Most options can be set using their actual names in the my.cnf.

Redically simple, intelligent and robust backup & recovery for MySQL

Percona XtraBackup is the world’s only open-source, free MySQL hot backup software that performs non-blocking backups for InnoDB and XtraDB databases. With Percona XtraBackup, you can achieve the following benefits:

Backups that complete quickly and reliably
Uninterrupted transaction processing during backups
Savings on disk space and network bandwidth
Automatic backup verification
Higher uptime due to faster restore time

Percona XtraBackup makes MySQL hot backups for all versions of Percona Server, MySQL, and MariaDB. It performs streaming, compressed, and incremental MySQL backups.

Percona XtraBackup works with MySQL, MariaDB, and Percona Server. It supports completely non-blocking backups of InnoDB, XtraDB, and HailDB storage engines. In addition, it can back up the following storage engines by briefly pausing writes at the end of the backup: MyISAM, Merge, and Archive, including partitioned tables, triggers, and database options.

Percona’s enterprise-grade commercial MySQL Support contracts include support for Percona XtraBackup. We recommend support for critical production deployments.

Percona XtraBackup is an high performance, low-profile and non-blocking open-source backup utility for InnoDB and XtraDB databases.

Currently is the only open-source tool that performs backups on 'MySQL-based' servers (MySQL, MariaDB, Percona Server) that doesn't lock your database during it. Backups are online, and queries and transactions continue to run without interruption ('hot backups').

It can back up data from InnoDB, XtraDB, and MyISAM tables on MySQL 5.0 and 5.1 servers, and it has many advanced features like partial, remote, compressed and incremental backups, multi-threaded file copying for performance and Point-in-time recovery.
