二、使用innobackupex预备全备

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。“准备”的主要作用正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也使得数据文件处于一致性状态。读取备份文件夹中的配置文件，然后innobackupex重做已提交事务，回滚未提交事务，之后数据就被写到了备份的数据文件(innodb文件)中，并重建日志文件。这一步隐式调用了2次xtrabackup –prepare。

语法：

innobackupex --apply-log --use-memory=4G /path/to/BACKUP-DIR/日期文件夹

例子：

[root@xqzt backup]# innobackupex --apply-log /backup/2016-09-04_18-01-55/

160904 18:04:24 innobackupex: Starting the apply-log operation

IMPORTANT: Please check that the apply-log run completes successfully.

           At the end of a successful apply-log run innobackupex

           prints "completed OK!".

如果执行正确，其最后输出的几行信息通常如下：completed OK!

在实现“准备”的过程中，innobackupex 通常还可以使用 --use-memory 选项来指定其可以使用的内存的大小，默认通常为 100M。如果有足够的内存可用，可以多划分一些内存给 prepare 的过程，以提高其完成速度。

三、使用innobackupex还原备份

innobackupex命令的--copy-back选项用于执行恢复操作，其通过复制所有数据相关的文件至mysql服务器DATADIR目录中来执行恢复过程。innobackupex通过backup-my.cnf来获取DATADIR目录的相关信息。

语法：

innobackupex --copy-back /path/to/BACKUP-DIR

innobackupex --copy-back --datadir=恢复的数据目录 /path/to/BACKUP-DIR

注：

  • datadir必须是为空的，innobackupex –copy-back不会覆盖已存在的文件
  • 还原时需要先关闭服务，如果服务是启动的，那么就不能还原到datadir。

例子

[root@xqzt mysql]# innobackupex --copy-back /backup/2016-09-04_18-01-55/

160904 18:06:31 innobackupex: Starting the copy-back operation

IMPORTANT: Please check that the copy-back run completes successfully.

           At the end of a successful copy-back run innobackupex

           prints "completed OK!".

160904 18:06:33 completed OK!

如果执行正确，其输出信息的最后几行通常如下：completed OK! 请确保如上信息的最行一行出现“innobackupex: completed OK!”。

如果服务器剩余空间不足，你可以使用 --move-back替换掉 --copy-back。

启动数据库

当数据恢复至DATADIR目录以后，还需要确保所有数据文件的属主和属组均为正确的用户，如mysql，否则，在启动mysqld之前还需要事先修改数据文件的属主和属组。如：

chown -R mysql.mysql 新的数据目录

现在可以启动mysql了

四、Xtrabackup备份文件的说明

查看备份的输出，使用innobakupex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令的目录中。

[root@xqzt backup]# tree -L 2 /backup/

/backup/

└── 2016-09-04_18-01-55

    ├── backup-my.cnf

    ├── ibdata1

    ├── ib_logfile0

    ├── ib_logfile1

    ├── ibtmp1

    ├── mysql

    ├── test

    ├── xtrabackup_binlog_info

    ├── xtrabackup_checkpoints

    ├── xtrabackup_info

    └── xtrabackup_logfile

4 directories, 9 files

在备份的同时，innobackupex还会在备份目录中创建如下文件：

(1)xtrabackup_checkpoints

包含备份类型（如完全或增量）、备份状态（如是否已经为prepared状态）和LSN(日志序列号)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，即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。

[root@xqzt 2016-09-04_18-01-55]# cat xtrabackup_checkpoints

backup_type = full-prepared

from_lsn = 0

to_lsn = 1626027

last_lsn = 1626027

compact = 0

recover_binlog_info = 0

(2)xtrabackup_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。

[root@xqzt 2016-09-04_18-01-55]# cat xtrabackup_info

uuid = 9e4c2078-7286-11e6-92a6-0800279b6e4d

name =

tool_name = innobackupex

tool_command = --defaults-file=/etc/my.cnf --user=root --password=... /backup/

tool_version = 2.4.4

ibbackup_version = 2.4.4

server_version = 5.6.30-log

start_time = 2016-09-04 18:01:56

end_time = 2016-09-04 18:01:58

lock_time = 0

binlog_pos = filename 'mysql-bin.000012', position '262'

innodb_from_lsn = 0

innodb_to_lsn = 1626027

partial = N

incremental = N

format = file

compact = N

compressed = N

encrypted = N

(3)xtrabackup_binlog_info

二进制日志文件及用于InnoDB或XtraDB表的二进制日志文件的当前position。

[root@xqzt 2016-09-04_18-01-55]# cat xtrabackup_binlog_info

mysql-bin.000012	262

(4)xtrabackup_logfile

开始以来的二进制日志，用于prepare的时候实现一致性

(5)backup-my.cnf

备份命令用到的配置选项信息；

[root@xqzt 2016-09-04_18-01-55]# cat backup-my.cnf

# This MySQL options file was generated by innobackupex.

# The MySQL server
