Percona XtraBackup 2.4.9Percona announces the GA release of Percona XtraBackup 2.4.9 on November 29, 2017. You can download it from our download site and 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.

New features:

  • Packages are now available for Ubuntu 17.10 (Artful).
  • xbcrypt now can decrypt files in parallel by specifying the number of threads with the --encrypt-threads option.
  • --copy-back option can now be used with --parallel option to copy the user data files in parallel (redo logs and system tablespaces are copied in the main thread).

Bugs Fixed:

  • Percona XtraBackup would fail to backup large databases on 32-bit platforms. Bug fixed #1602537.
  • Percona XtraBackup failed to build with GCC 7. Bug fixed #1681721.
  • Percona XtraBackup would hang during the prepare phase if there was not enough room in log buffer to accommodate checkpoint information at the end of the crash recovery process. Bug fixed #1705383.
  • When backup was streamed in tar format with the --slave-info option, output file xtrabackup_slave_info did not contain the slave information. Bug fixed #1707918.
  • If --slave-info option was used while backing up 5.7 instances, the master binary log coordinates were not properly displayed in the logs. Bug fixed #1711010.
  • innobackupex --slave-info would report a single m instead of slave info in the standard output. Bug fixed #1727920.
  • Percona XtraBackup would crash while preparing the 5.5 backup with utf8_general50_ci collation. Bug fixed #1533722 (Fungo Wang).
  • Percona XtraBackup would crash if --throttle option was used while preparing backups. Fixed by making this option available only during the backup process. Bug fixed #1691093.
  • Percona XtraBackup could get stuck if backups are taken with --safe-slave-backup option, while there were long-running queries. Bug fixed #1717158.

Other bugs fixed: #1678838, #1727922, and #1729241.

Release notes with all the bugfixes for version 2.4.9 are available in our online documentation. Please report any bugs to the launchpad bug tracker.
