Xtrabackup下载、安装以及全量备份请参考：

MySQL管理之使用XtraBackup进行热备

MySQL开源备份工具Xtrabackup备份部署

MySQL Xtrabackup备份和恢复

用XtraBackup实现MySQL的主从复制快速部署【主不锁表】

安装和使用 Percona 推出的 Xtrabackup 备份 MySQL

1，创建mysql备份用户

mysql -uroot –password=”” -e”CREATE USER ‘backup’@’192.168.%’ IDENTIFIED BY ‘123456’”;

mysql -uroot –password=”” -e”GRANT RELOAD, LOCK TABLES, REPLICATION CLIENT, CREATE TABLESPACE, SUPERON *.* TO ‘backup’@’192.168.%'”;

2，xtrabackup进行全量备份

备份命令：

xtrabackup –defaults-file=/etc/my.cnf–user=backup –password=”123456″ –port=3306 –backup–target-dir=/data/backups/mysql/full_incre_$(date +%Y%m%d)

PS: 2>/tmp/fullbackup.log 将备份信息放入文件中。

备份过程信息如下：
[root@data01 ~]# xtrabackup–defaults-file=/etc/my.cnf –user=backup –password=”123456″–port=3306 –backup –target-dir=/data/backups/mysql/full_incre_$(date+%Y%m%d)
xtrabackup version 2.2.9 based on MySQLserver 5.6.22 Linux (x86_64) (revision id: )
xtrabackup: uses posix_fadvise().
xtrabackup: cd to /home/data/mysql/data

3，xtrabackup进行增量备份

3.1先录入一张表，，实现第一次增量数据：
