4.5 恢复整个库
恢复命令：
xtrabackup --defaults-file=/etc/my.cnf--prepare --user=backup --password="123456"--target-dir=/data/backups/mysql/full_incre_20150319 2>/tmp/restore_end_3.log
停止mysql服务：
service mysqld5612 stop
开始rsync数据文件：
cd /data/backups/mysql/full_incre_20150319
rsync -rvt --exclude'xtrabackup_checkpoints' --exclude 'xtrabackup_logfile'? ./ /home/data/mysql/data
授予mysql访问权限：
chown -R mysql:mysql /home/data/mysql/data
启动mysql服务：
service mysqld5612 start

4.6，验证
登录mysql，看到以前在备份之后删除的t4以及t_incre_2表的数据已经通过2次增量备份恢复过来了，如下所示：
?
mysql> select * from t4;
+-----+---+
| a? | b |
+-----+---+
| aaa | 1 |
| bbb | 2 |
+-----+---+
2 rows in set (0.05 sec)
?
mysql> select * from t_incre_2;
+----+---+
| a | b |
+----+---+
| cc | 2 |
| dd | 2 |
+----+---+
2 rows in set (0.06 sec)
