XtraBackup 是一个用来备份 MySQLInnoDB 数据库的开源工具。

Percona XtraBackup 2.2.6 发布,此版本现已提供在下载页面Percona 软件库。此版本支持 Ubuntu 14.10 和 CentOS7。

更新内容如下:

新特性

  • 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 修复:

  • 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.

其他 bug 修复:#1379905, #1386013, #1072695, #1375241, #1182841#1343722.
