Percona XtraBackup 2.2.6 is now available

Percona is glad to announce the release of Percona XtraBackup 2.2.6 on November 3, 2014. Downloads are available from our download site here and Percona Software Repositories. We’re also happy to announce that Ubuntu 14.10 and CentOS 7 users can download, install, and upgrade Percona XtraBackup 2.2.6 from Percona’s 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.

New Features:

• Percona XtraBackup now reads server options from SHOW VARIABLES rather than my.cnf configuration file.
• Percona XtraBackup now has more verbose output during initial table scan (it will now print a diagnostic message before performing a tablespace scan, which may take a long time on systems with large numbers of tablespaces) and before starting a backup/apply-log/copy-back operation in innobackupex (it will now print a diagnostic message with a timestamp to make it easier for users to get duration of the operation.)

Bugs Fixed:

• innobackupex didn’t take the default datadir, which caused backups to fail if the datadir wasn’t specified in the my.cnf configuration file. Bug fixed #936934.
• innobackupex will now fail with an error when innobackupex –slave-info is used on a multi-threaded non-GTID slave, because Exec_Master_Log_Pos cannot be trusted for a multi-threaded slave. Bug fixed #1372679.
• InnoDB log scanning failure (bug #60788) would cause backups to fail. Fixed by porting the fix from MySQL 5.7. Bug fixed #1375383.
• Options --apply-log and --decompress weren’t marked as mutually exclusive, ie. if they were both specified, only --decompress would work, which could lead to MySQL instance being started with an unprepared backup. Fixed by making mutually exclusive categories of options: 1. --decompress, --decrypt; 2. --copy-back; 3. --move-back; 4. --apply-log. Bug fixed #1376874.
• innobackupex wasn’t creating directories specified in innodb_data_home_dir and innodb_log_group_home_dir when --copy-back option was used. Bug fixed #1382347.
• Percona XtraBackup now supports all option modifiers supported by upstream MySQL: skip, disable, enable, maximum, loose. Bug fixed #664128.
• Percona XtraBackup would fail to perform a full backup on Percona Server 5.5 if innodb_log_file_size variable wasn’t set in the [mysqld] section of my.cnf. Bug fixed #1334062.

Other bugs fixed: #1379905, #1386013, #1072695, #1375241, #1182841, and #1343722.
