Percona XtraBackup 8.0.4

Percona is glad to announce the release of Percona XtraBackup 8.0.4 on December 10, 2018. Downloads are available from our download site and from apt and yum repositories.

Percona XtraBackup enables MySQL backups without blocking user queries, making it ideal for companies with large data sets and mission-critical applications that cannot tolerate long periods of downtime. Offered free as an open source solution, it drives down backup costs while providing unique features for MySQL backups.

This release of Percona Xtrabackup is a General Availability release ready for use in a production environment.

Please note the following about this release:

  • The deprecated innobackupex has been removed. Use the xtrabackup command to back up your instances: $ xtrabackup --backup --target-dir=/data/backup

  • When migrating from earlier database server versions, backup and restore and using Percona XtraBackup 2.4 and then use mysql_upgrade from MySQL 8.0.x

  • If using yum or apt repositories to install Percona XtraBackup 8.0.4, ensure that you have enabled the new tools repository. You can do this with the percona-release enable tools release command and then install the percona-xtrabackup-80 package.

All Percona software is open-source and free. We are grateful to the community for the invaluable contributions to Percona XtraBackup. We would especially like to highlight the input of Alexey Kopytov who has been actively offering improvements and submitting bug reports for Percona XtraBackup.

  • Percona XtraBackup 8.0.4 is based on MySQL 8.0.13 and fully supports Percona Server for MySQL 8.0 series and MySQL 8.0 series.
