Percona XtraBackup 2.2.8 发布了，XtraBackup 是一个用来备份MySQL 的InnoDB 数据库的开源工具。该版本基于 MySQL 5.6.22，修复了一些 bug：
Bugs Fixed:
-
Incremental backups would fail if the number of undo tablespaces ( innodb_undo_tablespaces ) was more than . This was caused by innobackupex removing the undo tablespaces during the prepare phase. Bug fixed #1363234 .
-
Fixed multiple memory leaks detected by AddressSanitizer. Bug fixed #1395143 .
-
innobackupex could fail when preparing backup that was taken from Percona Server 5.5 with log files ( innodb_log_file_size ) bigger than
4G. The root cause was that the last checkpoint LSN offset in log group is stored at different offsets inibdata1for Percona Server 5.5 and MySQL 5.6 when the total size of log files is greater than4G. Bug fixed #1403237 . -
Percona XtraBackup out-of-source builds failed. Bug fixed #1402450 .
