----NOTE:
 mysqlbackup: INFO: Could not find binlog index file. binlogs will not be copied for this backup.
 Point-In-Time-Recovery will not be possible.
 If this is online backup then server may not have started with --log-bin.
 You may specify its location with --log-bin-index option.

--3.还原指定表空间
**************************************************************

--3.1 合并增量备份到全备

ls /backupinc/
2015-04-01_10-03-16  2015-04-01_10-11-51


mysqlbackup --backup-dir=/backup/2015-04-01_09-39-09 \
--incremental-backup-dir=/backupinc/2015-04-01_10-03-16 \
apply-incremental-backup 


mysqlbackup --backup-dir=/backup/2015-04-01_09-39-09 \
--incremental-backup-dir=/backupinc/2015-04-01_10-11-51 \
apply-incremental-backup 



--3.2 模拟删除指定表空间

#cat /usr/local/mysql/my.cnf |grep datadir
datadir=/usr/local/mysql/data


MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+

| performance_schema |
| test               |
| wind               |
+--------------------+
6 rows in set (0.01 sec)


MariaDB [wind]> select count(*) from t1;
+----------+
| count(*) |
+----------+
|  3000000 |
+----------+
1 row in set (0.60 sec)


MariaDB [(none)]> drop database wind;
Query OK, 1 row affected (0.24 sec)

MariaDB [(none)]> commit;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> show databases;
+--------------------+

| test               |
+--------------------+
5 rows in set (0.00 sec)


--3.3 还原指定表空间

mysqlbackup  --defaults-file=/usr/local/mysql/my.cnf   \
--datadir=/usr/local/mysql/data/   \
--log-bin-index=/usr/local/mysql/mysql_logs/binary_log/mysqldb01-bin.index \
--backup-dir=/backup/2015-04-01_09-39-09 \
--databases="wind" \
copy-back 





chown -R mysql /usr/local/mysql
chgrp -R mysql /usr/local/mysql


 
--3.4验证表空间恢复情况


MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| jason              |
| mysql              |
| performance_schema |
