Percona XtraBackup 2.1.1 GA 发布,改进记录包括:
New Features:
- Percona XtraBackup 支持 紧缩备份. 可节省不少磁盘空间。包含新的 innobackupex –rebuild-threads 参数可用于指定在重构第二索引 (innobackupex --apply-log --rebuild-indexes) 启动的线程数。这个允许在重建索引时对单个表进行并行处理
- Percona XtraBackup 实现了 加密备份.
- innobackupex 现在使用 Perl’s
DBD::MySQL
包跟服务器通讯,替换 MySQL 命令行客户端 - 移除对 InnoDB 5.0 和 InnoDB 5.1 内建的支持
- 完全删除 --remote-host 参数
- Percona XtraBackup 可使用 XtraDB changed page tracking 特性来执行 增量备份
Bugs Fixed:
- innobackupex is using
SHOW MASTER STATUS
to obtain binlog file and position. This could trigger a bug if the server being backed up was standalone server (neither master nor slave in replication) and binlog information wasn’t available. Fixed by not creatingxtrabackup_binlog_info
file when binlog isn’t available. Bug fixed #1168513. - Percona XtraBackup would leave
xbtemp
temp files behind due to a typo. Bug fixed #1172016. - Percona XtraBackup would assume the table has been dropped if the tablespace was renamed after it was scanned by XtraBackup on startup and before XtraBackup attempted to copy it. Bug fixed #1079700.
- Orphaned
xtrabackup_pid
file left inside tmpdir could cause SST to fail. Fixed by fix checking ifxtrabackup_pid
file exists once innobackupex starts, and try to remove it or fail if it cannot be removed. Bug fixed #1175860. - xtrabackup –stats option would not work with server datadir if the server isn’t running and logs were in a separate directory. Bug fixed #1174314.
Other bugs fixed: bug fixed #1166713, bug fixed #1175581, bug fixed #1175318, bug fixed #1175309, bug fixed #1176198, bug fixed #1175566.
