XtraBackup 是一个用来备份 MySQL 的 InnoDB 数据库的开源工具。
Percona XtraBackup 2.2.7 发布，此版本现已提供在下载页面或者 Percona 软件库。
Non-default value for innodb_log_block_size variable would cause assertion when preparing the backup. Bug fixed #1391216.
When Percona XtraBackup would run FLUSH ENGINE LOGS during the backup process on GTID master, command was recorded to the slave’s binary log as well。Bug fixed #1394632.
FLUSH ENGINE LOGS
Exporting tables was inefficient when backup contained a large (and unrelated) change buffer. Bug fixed #1366065 (Davi Arnaut).
innobackupex was printing the GTID even if the GTID mode was disabled which could cause confusion since it wasn’t incrementing. Bug fixed #1391041.
其他 bug 修复：bug #1386157.
