This release is purely composed of bug fixes and is the current stable release of Percona Xtrabackup.

All of Percona’s software is open-source and free, all the details of the release and its development process can be found in the 1.6.2 milestone at Launchpad.

The --version option has been added to the xtrabackup binary for printing its version. Previously, the version was displayed only while executing the binary without arguments or performing a backup. Bug Fixed: #610614 (Alexey Kopytov).

• As exporting tables should only be used with innodb-file-per-table set in the server, the variable is checked by xtrabackup when using the --export option. It will fail before applying the archived log without producing a potentially unusable backup. Bug Fixed: #758888 (Alexey Kopytov).

• When creating an InnoDB with its own tablespace after taking a full backup, if the log files have been flushed, taking an incremental backup based on that full one would not contain the added table. This has been corrected by explicitly creating the tablespace before applying the delta files in such cases. Bug Fixed: #766607(Alexey Kopytov).
• In some cases, innobackupex ignored the specified xtrabackup binary with the --ibbackup option. Bug Fixed: #729497 (Stewart Smith).
• Minor file descriptors leaks in error cases were fixed. Bug Fixed: #803718 (Stewart Smith).

• Improvements and fixes on the XtraBackup Test Suite: #744303, #787966 (Alexey Kopytov)
• Improvements and fixes on platform-specific distribution: #785556 (Ignacio Nin)
• Improvements and fixes on the XtraBackup Documentation: #745185, #721339 (Rodrigo Gadea)
