3.4 进行第二天的增量备份
备份命令：
xtrabackup --defaults-file=/etc/my.cnf--backup --user=backup --password="123456" --port=3306 --target-dir=/data/backups/mysql/incre_20150321/--incremental-basedir=/data/backups/mysql/incre_20150320 2>/tmp/incre_backup_2.log
备份信息记录如下：
[root@data01 ~]# more /tmp/incre_backup_2.log

4，xtrabackup进行增量恢复
4.1为了验证比对，先删除两个增量备份前表里面的数据
