A utility like mysqldump is very useful for backing up MySQL data and table schema. However, backups are usually made only once a day or at some other regular interval. If data is lost on your system several hours after the last backup is completed, you may not be able to recover it. There are a few methods by which you can continuously protect data. One method that you can use to be able to recover interim data is to use binary logs. A binary log will record all SQL transactions on a server as they are executed. Some administrators try to minimize any logging because of concerns about server performance. However, on average, binary logging will slow a server by only one percent. In return, though, it allows for up to the minute data recovery.
