XtraBackup 是一个用来备份 mysql”>MySQL 的 innodb”>InnoDB 数据库的开源工具。
此版本主要是 bug 修复：
- Decrypting backup with the wrong key would make the backup unusable and unrecoverable. Bug fixed #1413044.
- XtraDB Changed Page Tracking wasn’t working with innobackupex. Bug fixed #1436793.
- Fixed Percona XtraBackup assertion caused by dirty pages remaining in the buffer pool after the log was fully applied. Bug fixed #1368846.
- Backup will not be prepared and innobackupex will stop with an error if the transaction log file is corrupted and it wasn’t applied to the intended LSN. Previously this was showing only as a warning. Bug fixed #1414221.
- New status
log-appliedis introduced for backup prepared with
--redo-onlyto avoid making the backup unusable by preparing full or incremental backup without
--redo-onlyand then applying next incremental on top of it. Incremental backup now can be applied only to backup in
log-appliedstate, but not to
full-preparedas it was earlier. Bug fixed#1436790.
