**percona mysql备份与恢复(一)**

XtraBackup 是开源的热备mysql的软件，可以备份InnoDB, XtraDB, and MyISAM类型的表，它是由如下三个工具组成的

1.innobackupex：有perl脚本封装的，可以备份MyISAM, InnoDB, and XtraDB类型表，推荐使用此工具  
2.xtrabackup：由c语言编译的，只copy表InnoDB和XtraDB的数据  
3.xbstream：允许从streaming and extracting文件压缩/抽取xbstream格式文件

innobackupex  
innobackupex有更强的功能，它整合了xtrabackup和其他的一些功能，他不但可以全量备份/恢复，还可以基于时间的增量备份与恢复。

innobackupex备份原理  
innobackupex首先调用xtrabackup来备份innodb数据文件，当xtrabackup完成后，innobackupex就查看文件xtrabackup\_suspended ；然后执行“FLUSH TABLES WITH READ LOCK”来备份其他的文件

innobackupex恢复原理  
innobackupex首先读取my.cnf，查看变量(datadir,innodb\_data\_home\_dir,innodb\_data\_file\_path,innodb\_log\_group\_home\_dir)对应的目录是存在，确定相关目录存在后，然后先copy myisam表和索引，然后在copy innodb的表、索引和日志

详细参考：[http://www.percona.com/doc/percona-xtrabackup/innobackupex/how\_innobackupex\_works.html][http_www.percona.com_doc_percona-xtrabackup_innobackupex_how_innobackupex_works.html]

下载：  
\[root@localhost data\]\# wget [ http://www.percona.com/redir/downloads/XtraBackup/XtraBackup-2.0.0/RPM/rhel5/i386/percona-xtrabackup-2.0.0-417.rhel5.i386.rpm][http_www.percona.com_redir_downloads_XtraBackup_XtraBackup-2.0.0_RPM_rhel5_i386_percona-xtrabackup-2.0.0-417.rhel5.i386.rpm]

安装：  
\[root@localhost data\]\# rpm -ivh percona-xtrabackup-2.0.0-417.rhel5.i386.rpm

全量的备份与恢复

**步骤**  
\# innobackupex --user=root   /data/backup/  
\# innobackupex --apply-log   /data/backup/2012-06-27\_16-32-57/  
先把datadir目录更名，因为恢复时，datadir目录不为空，恢复会终止，防止意外覆盖  
\# innobackupex --copy-back   /data/backup/2012-06-27\_16-32-57/

备份：  
\[root@localhost data\]\# innobackupex --user=root   /data/backup/

在创建全量备份后，备份文件是不能restore的，因为这个初始创建的备份只是简单的copy过程，而innodb是事务引擎，所以还需要通过log文件replay committed的事务和回滚uncommitted事务，这样数据库就达到一致的状态，可以restore了。
