mysql enterprise backup入门使用

**************************************************************
--1.全备
**************************************************************

#mysqlbackup --defaults-file=/usr/local/mysql/my.cnf  --host=127.0.0.1   --port=3306  --protocol=tcp  --user=root  --password=passwd123!  --databases="wind" --with-timestamp   --backup-dir=/backup   --log-bin-index=/usr/local/mysql/mysql_logs/binary_log/mysqldb01-bin.index backup-and-apply-log 




----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.




#cat  /backup/2015-04-01_09-39-09/meta/backup_variables.txt  |grep ‘lsn‘

end_lsn=70249846
start_lsn=70249472


/***************************參数


[backup_variables]
apply_log_done=1    #　是否释放检測ibbackup_logfile文件(0表示没有,1表示已经释放)
binlog_index=mysqldb01-bin.index  #二进制日志索引文件
binlog_position=mysqldb01-bin.000011:338   #二进制日志文件大小
end_lsn=70249846   # 结束LSN点
has_external_plugins=0    #外部插件
is_compressed=0  #是否压缩(0:否,1:是)
is_incremental=0    #是否是增量为增量备份文件(0:否,1:是)
is_incremental_with_redo_log_only=0  仅仅配置重做日志,当输入数据大小重做日志大小时,会有一场抛出
is_onlyinnodb=0  #是否仅仅备份了innodb的表
is_partial=1   #是server备份还是部分备份（0表示全server备份,1表示部分备份）
is_skip_unused_pages=0  
meb_version=3.12.0  #版本
start_lsn=70249472  #開始备份的LSN点

---2.增量备份
**************************************************************

mysqlbackup --defaults-file=/usr/local/mysql/my.cnf  --host=127.0.0.1   --port=3306  --protocol=tcp  --user=root  --password=passwd123!  --databases="wind" --with-timestamp  --log-bin-index=/usr/local/mysql/mysql_logs/binary_log/mysqldb01-bin.index --incremental --start-lsn=70249846  --incremental-backup-dir=/backupinc backup   




mysqlbackup --defaults-file=/usr/local/mysql/my.cnf  --host=127.0.0.1   --port=3306  --protocol=tcp  --user=root  --password=passwd123!  --databases="wind" --with-timestamp  --log-bin-index=/usr/local/mysql/mysql_logs/binary_log/mysqldb01-bin.index --incremental --start-lsn=138861169  --incremental-backup-dir=/backupinc  backup 


**************************************************************
--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           |
+--------------------+
| information_schema |
| jason              |
| mysql              |
| 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;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| jason              |
| mysql              |
| performance_schema |
| 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 |
| test               |
| wind               |
+--------------------+
6 rows in set (0.01 sec)


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