Percona XtraBackup 2.3.3 is now available

Percona XtraBackup 2.3.3 for MySQL Percona is glad to announce the release of Percona XtraBackup 2.3.3 on December 17th, 2015. Downloads are available from our download site or Percona Software 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, Percona XtraBackup drives down backup costs while providing unique features for MySQL backups.

This release is the current GA (Generally Available) stable release in the 2.3 series.

Bugs Fixed:

  • Database directories were not removed if DROP DATABASE happened during the backup. Bug fixed #1461735.
  • Backup would fail if Store backup history on the server feature was enabled and backup was taken from server without binary log enabled. Bug fixed #1509812.
  • Percona XtraBackup now fails with descriptive error message if --defaults-extra-file option is not specified first. Bug fixed #1511451.
  • Backup would fail if --rsync option was used without specifying temporary folder. Bug fixed #1511701.
  • Fixed Percona XtraBackup crash which happened when it was used for SST on MariaDB Galera Cluster caused by double free of datadir variable. Bug fixed #1512281.
  • --move-back option did not respect the innodb_log_group_home_dir and innodb_data_home_dir options which caused ib_logfiles and data files not to be moved back to correct location. Bug fixed #1512616.
  • xtrabackup_binlog_info was not updated correctly when applying incremental backups. Bug fixed #1523687.
  • When using a --defaults-file option Percona XtraBackup would complain about datadir being mismatched if it wasn’t explicitly set in the defaults file. Bug fixed #1508448.
  • Fixed build issues by adding missing check in cmake script for xxd presence. Bug fixed #1511267.
  • Percona XtraBackup would terminate backup process without error if --slave-info option was used on a server not running as a replication slave. Bug fixed #1513520.
  • innobackupex when used with --stream option would create an empty directory with a timestamp as a name. Bug fixed #1520569.

Other bugs fixed #1523728 and #1507238.
