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：
?
mysql> create table t4 select 'aaa' asa, 1 as b;
Query OK, 1 row affected (0.36 sec)
Records: 1 Duplicates: 0? Warnings: 0
?
mysql>
mysql> insert into t4 select 'bbb',2;
Query OK, 1 row affected (0.05 sec)
Records: 1 Duplicates: 0? Warnings: 0
?
mysql>
?
?
3.2 再进行增量备份1
xtrabackup --defaults-file=/etc/my.cnf--backup --user=backup --password="123456" --port=3306 --target-dir=/data/backups/mysql/incre_20150320/--incremental-basedir=/data/backups/mysql/full_incre_201503192>/tmp/incre_backup_1.log
?
查看备份日志信息：
