每日凌晨2:00进行dump对相应数据库进行备份,同时对相应数据库进行binlog日志文件更新。
如果发现数据库错误,只需要先恢复上一个dump的备份,然后再还原当天的binlog日志文件。
举例:
每日12:00执行:
mysqldump database --flush-logs -uroot -p --opt > database_20020601.sql
按照日期规则执行。
如果想恢复到今早10点的数据库,那么:
1、完整备份整个当前数据库
cd /var/lib/mysql
mysqldump -uroot -p123456 mydata > mydata.bak
2、删除当前备份好的数据库
rm -rf mydata
3、先用dump恢复
mysql -uroot -p123456
mysql database -uroot -p123456
4、再用binlog按时间恢复
mysqlbinlog --stop-date="2011-07-28 10:18:49" /var/lib/mysql/mysql-bin.000006 | mysql -uroot -p123456
备注:
1、最好要把dump备份和binlog备份保存在异地--异地备份。
2、mysql主从复制。
