Percona XtraBackup 2.2.4

Percona is glad to announce the release of Percona XtraBackup 2.2.4 on September 12th 2014. Downloads are available from our download site here and from apt and yum repositories.

This release is the current stable release in the 2.2 series.

New Features

Percona XtraBackup has implemented support for Galera GTID autorecovery. Percona XtraBackup retrieves the GTID information, after backing up a server with backup locks support, from the InnoDB trx header on recovery and creates the xtrabackup_galera_info during that stage.

Bugs Fixed

Percona XtraBackup is now built with system zlib library instead of the older bundled one. Bug fixed #1108016.

apt-get source was downloading older version of Percona XtraBackup. Bug fixed #1363259.

innobackupex would ignore the innobackupex --databases without innobackupex --stream option and back up all the databases. Bug fixed #569387.

rsync package wasn’t a dependency although it is required for the innobackupex --rsync option. Bug fixed #1259436.

innobackupex --galera-info was checking only for non-capitalized wsrep_* status variables which was incompatible with MariaDB Galera Cluster 10.0. Bug fixed #1306875.

Percona XtraBackup now supports MariaDB GTID. Bugs fixed #1329539 and #1326967 (Nirbhay Choubey).

Percona XtraBackup would crash trying to remove absent table from InnoDB data dictionary while preparing a partial backup. Bug fixed #1340717.

MariaDB 10.1 is now added to the list of supported servers. Bug fixed #1364398.

Percona XtraBackup would fail to restore (copy-back) tables that have partitions with their own tablespace location. Bug fixed #1322658.

All of Percona’s software is open-source and free, all the details of the release can be found in the 2.2.4 milestone at Launchpad.
