Percona announces the release of Percona XtraBackup 2.3.9 on July 24, 2017. 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. New Features Bugs Fixed:
  • Percona XtraBackup would crash when being prepared if the index compaction was enabled. Bug fixed #1192834.
  • Fixed build failure on Debian Stretch by adding support for building with OpenSSL 1.1. Bug fixed #1678947.
  • xbstream could run out of file descriptors while extracting the backup which contains many tables. Bug fixed #1690823.
  • Percona XtraBackup incorrectly determined use of master_auto_postion on a slave, and thus generated invalid xtrabackup_slave_info file. Bug fixed #1705193.
  • Percona XtraBackup would crash while backing up MariaDB 10.2.x with --ftwrl-* options. Bug fixed #1704636.
  • Along with xtrabackup_checkpints file, xtrabackup now copies xtrabackup_info file into directory specified by --extra-lsndir option. Bug fixed #1600656.
  • GTID position was not recorded when --binlog-info option was set to AUTO. Bug fixed #1651505.
Release notes with all the bugfixes for Percona XtraBackup 2.3.9 are available in our online documentation. Bugs can be reported on the launchpad bug tracker.

    Hi! Is it possible that the standard behavior now is creating a compressed backup? I am NOT using the --compress option in my scripts but since the upgrade to 2.3.9 all the files are generated compressed (.ibd.qp), and I had to add a line to decompress the backup, because I couldn't find a "--no-compress" option:

    original line:

    and I had to add:

    scripts are running on CentOS Linux 7

    Thanks for your help.
