# 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](http://www.percona.com/downloads/XtraBackup/Percona-XtraBackup-8.0.4/) 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](https://www.percona.com/doc/percona-xtrabackup/2.4/how-tos.html#recipes-for-xtrabackup)
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*.

## New Features
