    一.xtrabackup概述

    1>.Percona公司概述

      Percona是无偏向开源数据库解决方案的领先提供商,该解决方案使组织能够轻松,安全且负担得起地保持业务敏捷性,最小化风险并保持竞争力。
    
      和MariaDB一样,Percona也有基于MySQL分支开源的数据库产品,即percona-server。
    
      Percona和Google及Sun Microsystems等公司为InnoDB Plugin提供了patch补丁包,使其性能发挥至极致。   XtraDB存储引擎是由Percona开发的一款MySQL数据库的高性能存储引擎,其目的是用来代替InnoDB存储引擎,可用于需要更高性能的环境。   XtraDB可以看作是InnoDB存储引擎的增强版本,它在InnoDB上进行了大量的修改和patched,它完全兼容InnoDB,且提供了很多InnoDB不具备的有用的功能。例如:在多核CPU上面的性能和伸缩性要更好;对于内存的分配和使用也要更好;也解除了InnoDB的很多限制;提供了比InnoDB更多的配置和性能监控参数。   博主推荐阅读:     https:

    InnoDB发展历史:
      InnoDB引擎是由InnobaseOy公司开发。
    
      2001年,Innobase公司开始与MySQL AB公司进行合作并开源InnoDB存储引擎的代码。
    
      Oracle公司在2005年以迅雷不及掩耳之势收购了Innobase公司。
    
      2008年Sun公司收购MySQL AB公司。
    
      2009年Oracle收购Sun公司,而MySQL数据库最终到了Oracle的手中,InnoDB存储引擎和MySQL终于又在一起了。
    
      2008年发布InnoDB Plugin,适用于MySQL 5.1版本,这是Oracle创建的下一代InnoDB引擎,其拥有者是InnoDB而不是MySQL。
    
      Google,Percona,Sun Microsystems等公司为InnoDB Plugin提供了patch补丁包,使其性能发挥至极致。
    
      MySQL 5.1.38前的版本中,当你需要安装InnoDB Plugin时,必须下载Plugin的文件,解压后再进行一系列的安装。

    2>.什么是xtrabackup

      Xtrabackup是percona提供的mysql数据库备份工具,惟一开源的能够对innodb和xtradb数据库进行热备的工具。
     
        Xtrabackup的特点:
          备份还原过程快速、可靠
          备份过程不会打断正在执行的事务
          能够基于压缩等功能节约磁盘空间和流量
          自动实现备份检验
          开源,免费

    3>.xtrabackup的新版变化

    Xtrabackup2.2版之前包括4个可执行文件:
      innobackupex: 
        Perl语言编写的脚本
      xtrabackup: 
        C/C++ 编译的二进制,
        是用来备份 InnoDB 表的,不能备份非 InnoDB 表,和 MySQL Server 没有交互
      xbcrypt: 
        加解密   
      xbstream: 
        支持并发写的流文件格式  
    
    温馨提示:
      innobackupex脚本用来备份非InnoDB表,同时会调用xtrabackup命令来备份InnoDB表,还会和MySQL Server发送命令进行交互,如加全局读锁(FTWRL)、获取位点(SHOW SLAVE STATUS)等。
      即innobackupex是在 xtrabackup 之上做了一层封装实现的xtrabackup版本升级到2.4后,相比之前的2.1有了比较大的变化:innobackupex 功能全部集成到xtrabackup里面,只有一个binary程序,另外为了兼容考虑,innobackupex作为xtrabackup的软链接,即xtrabackup现在支持非Innodb表备份,并且Innobackupex在下一版本中移除,建议通过xtrabackup替换innobackupex.
      截止2019年11月7日,xtrabackup最新版本已发布到8.0.7(直接从2.4版本跳到8.0版本)。

    二.xtrabackup用法概述

    1>.备份

    innobackupex [option] BACKUP-ROOT-DIR
    
    选项说明:[option]
      --user:
        该选项表示备份账号
      --password:
        该选项表示备份的密码
      --host:
        该选项表示备份数据库的地址
      --databases:
        该选项接受的参数为数据库名,如果要指定多个数据库,彼此间需要以空格隔开;如:"xtra_test dba_test",同时,在指定某数据库时,也可以只指定其中的某张表。如:"mydatabase.mytable"。该选项对innodb引擎表无效,还是会备份所有innodb表
      --defaults-file:
        该选项指定从哪个文件读取MySQL配置,必须放在命令行第一个选项位置
      --incremental:
        该选项表示创建一个增量备份,需要指定--incremental-basedir
      --incremental-basedir:
        该选项指定为前一次全备份或增量备份的目录,与--incremental同时使用
      --incremental-dir:
        该选项表示还原时增量备份的目录
      --include=name:
        指定表名,格式:databasename.tablename

    2>.预处理(Prepare)

    innobackupex --apply-log [option] BACKUP-DIR
    
    选项说明:[option]   
    --apply-log:
        一般情况下,在备份完成后,数据尚且不能用于恢复操作,因为备份的数据中可能会包含尚未提交的事务或已经提交但尚未同步至数据文件中的事务。因此,此时数据文件仍处理不一致状态。此选项作用是通过回滚未提交的事务及同步已经提交的事务至数据文件使数据文件处于一致性状态   
    --use-memory:
        和--apply-log选项一起使用,当prepare 备份时,做crash recovery分配的内存大小,单位字节,也可1MB,1M,1G,1GB等,推荐1G   --export:
        表示开启可导出单独的表之后再导入其他Mysql中   
    --redo-only:
        此选项在prepare base full backup,往其中合并增量备份时候使用,但不包括对最后一个增量备份的合并

    3>.还原(innobackupex --copy-back [选项] BACKUP-DIR)

    innobackupex --move-back [选项] [--defaults-group=GROUP-NAME] BACKUP-DIR
    
    选项说明:
     --copy-back:
      做数据恢复时将备份数据文件拷贝到MySQL服务器的datadir
     --move-back:
      这个选项与--copy-back相似,唯一的区别是它不拷贝文件,而是移动文件到目的地。这个选项移除backup文件,用时候必须小心。
      使用场景:没有足够的磁盘空间同事保留数据文件和Backup副本
    
    还原注意事项:
      1.datadir 目录必须为空。除非指定innobackupex --force-non-empty-directorires选项指定,否则--copy-backup选项不会覆盖
      2.在restore之前,必须shutdown MySQL实例,不能将一个运行中的实例restore到datadir目录中
      3.由于文件属性会被保留,大部分情况下需要在启动实例之前将文件的属主改为mysql,这些文件将属于创建备份的用户
        chown -R mysql:mysql /data/mysql
        以上需要在用户调用innobackupex之前完成
        --force-non-empty-directories:
          指定该参数时候,使得innobackupex --copy-back或--move-back选项转移文件到非空目录,已存在的文件不会被覆盖。
          如果--copy-back和--move-back文件需要从备份目录拷贝一个在datadir已经存在的文件,会报错失败

    4>.备份生成的相关文件

    使用innobackupex备份时,其会调用xtrabackup备份所有的InnoDB表,复制所有关于表结构定义的相关文件(.frm)、以及MyISAM、MERGE、CSV和ARCHIVE表的相关文件,同时还会备份触发器和数据库配置信息相关的文件。这些文件会被保存至一个以时间命名的目录中,在备份时,innobackupex还会在备份目录中创建如下文件:
      (1)xtrabackup_info:
          innobackupex工具执行时的相关信息,包括版本,备份选项,备份时长,备份LSN(log sequence number日志序列号),BINLOG的位置   (
    2)xtrabackup_checkpoints:
          备份类型(如完全或增量)、备份状态(如是否已经为prepared状态)和LSN范围信息,每个InnoDB页(通常为16k大小)都会包含一个日志序列号LSN。LSN是整个数据库系统的系统版本号,每个页面相关的LSN能够表明此页面最近是如何发生改变的   (
    3)xtrabackup_binlog_info:
          MySQL服务器当前正在使用的二进制日志文件及至备份这一刻为止二进制日志事件的位置,可利用实现基于binlog的恢复   (
    4)backup-my.cnf:
          备份命令用到的配置选项信息   (
    5)xtrabackup_logfile:
          备份生成的日志文件

    三.xtrabackup备份还原概述

    1>.旧版(2.4版本以前)xtrabackup完全备份及还原

    (1)在原主机
        innobackupex --user=root /backups
        scp -r /backups/2018-02-23_11-55-57/ 目标主机:/data/
    
    (2)在目标主机
        innobackupex --apply-log /data/2018-02-23_11-55-57/
        systemctl stop mariadb
        rm -rf /var/lib/mysql/*
        innobackupex --copy-back /data/2018-02-23_11-55-57/
        chown -R mysql.mysql /var/lib/mysql/
        systemctl start mariadb

    2>. 新版xtrabackup完全备份及还原

    (1)在原主机做完全备份到/backups
        xtrabackup --backup --target-dir=/backups/
        scp -r /backups/* 目标主机:/backups
    (2)在目标主机上
      1)预准备:
        确保数据一致,提交完成的事务,回滚未完成的事务     xtrabackup
    --prepare --target-dir=/backups/   2)复制到数据库目录     注意:数据库目录必须为空,MySQL服务不能启动     xtrabackup --copy-back --target-dir=/backups/   3)还原属性     chown -R mysql:mysql /var/lib/mysql   4)启动服务     systemctl start mariadb

    3>.旧版xtrabackup完全,增量备份及还原

    (1)在原主机
        innobackupex /backups
        mkdir /backups/inc{1,2}
      修改数据库内容
        innobackupex --incremental /backups/inc1 --incremental-basedir=/backups/2018-02-23_14-21-42(完全备份生成的路径)
      再次修改数据库内容
        innobackupex --incremental /backups/inc2 --incremental-basedir=/backups/inc1/2018-02-23_14-26-17 (上次增量备份生成的路径)
        scp -r /backups/* 目标主机:/data/
    
    (2)在目标主机
      不启动mariadb
      rm -rf /var/lib/mysql/*
      innobackupex --apply-log --redo-only /data/2018-02-23_14-21-42/
      innobackupex --apply-log --redo-only /data/2018-02-23_14-21-42/ --incremental-dir=/data/inc1/2018-02-23_14-26-17
      innobackupex --apply-log /data/2018-02-23_14-21-42/ --incremental-dir=/data/inc2/2018-02-23_14-28-29/
      ls /var/lib/mysql/
      innobackupex --copy-back /data/2018-02-23_14-21-42/
      chown -R mysql.mysql /var/lib/mysql/
      systemctl start mariadb

    4>.新版xtrabackup完全,增量备份及还原

    (1)备份过程
      1)完全备份:xtrabackup --backup --target-dir=/backups/base
      2)第一次修改数据
      3)第一次增量备份
        xtrabackup --backup --target-dir=/backups/inc1 --incremental-basedir=/backups/base
      4)第二次修改数据
      5)第二次增量
        xtrabackup --backup --target-dir=/backups/inc2 --incremental-basedir=/backups/inc1
      6)scp -r /backups/* 目标主机:/backups/
      备份过程生成三个备份目录
        /backups/{base,inc1,inc2}
    
    (2)还原过程
      1)预准备完成备份,此选项--apply-log-only 阻止回滚未完成的事务
        xtrabackup --prepare --apply-log-only --target-dir=/backups/base
      2)合并第1次增量备份到完全备份,
        xtrabackup --prepare --apply-log-only --target-dir=/backups/base --incremental-dir=/backups/inc1
      3)合并第2次增量备份到完全备份:最后一次还原不需要加选项--apply-log-only
        xtrabackup --prepare --target-dir=/backups/base --incremental-dir=/backups/inc2
      4)复制到数据库目录,注意数据库目录必须为空,MySQL服务不能启动
        xtrabackup --copy-back --target-dir=/backups/base
      5)还原属性:chown -R mysql:mysql /var/lib/mysql
      6)启动服务:systemctl start mariadb

    5>.xtrabackup单表导出和导入(最好使用Mariadb 10.2及以上版本试验)

    (1)单表备份
      innobackupex --include='hellodb.students' /backups
    (2)备份表结构
      mysql -e 'show create table hellodb.students' > student.sql
    (3)删除表
      mysql -e 'drop table hellodb.students‘
    (4)innobackupex --apply-log --export /backups/2018-02-23_15-03-23/
    (5)创建表
      mysql>CREATE TABLE `students` (
      `StuID` int(10) unsigned NOT NULL AUTO_INCREMENT,
      `Name` varchar(50) NOT NULL,
      `Age` tinyint(3) unsigned NOT NULL,
      `Gender` enum('F','M') NOT NULL,
      `ClassID` tinyint(3) unsigned DEFAULT NULL,
      `TeacherID` int(10) unsigned DEFAULT NULL,
      PRIMARY KEY (`StuID`)
      ) ENGINE=InnoDB AUTO_INCREMENT=26 DEFAULT CHARSET=utf8
    (6)删除表空间
      alter table students discard tablespace;
    (7)cp /backups/2018-02-23_15-03-23/hellodb/students.{cfg,exp,ibd} /var/lib/mysql/hellodb/
    (8)chown -R mysql.mysql /var/lib/mysql/hellodb/
    (9)mysql>alter table students import tablespace;
