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。 Bugs 修复 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. 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. 更多改进内容请看在线文档。 Percona XtraBackup 2.2.7 发布下载地址
