Any Web developer who creates high-volume websites, packaged applications, or business critical systems, can run into serious problems if his/her MySQL database gets corrupted. In most cases, corruption occurs when the developer tries to mount database, open/drop/access a table, or modify the database. To judge the exact level of MySQL database corruption and find the correct way to repair database, the developer needs to view MySQL log.

 

While MySQL log helps the developer to get pass database corruption in most cases, there are many situations when a database remains corrupted even after executing the steps mentioned in the log file. In such situations, the developer needs to restore the database from an updated backup. But, in situations where the database backup is unavailable or incomplete, the developer needs to opt for a third-party MySQL recovery application.

 

A MySQL recovery utility repairs and recovers logically damaged MySQL database objects like tables, views, index, columns, and more. The MySQL database recovery tool ensures complete safety of the database as it performs repair process on the copy of the original database. Such database recovery tools also provide complete preview of repaired database components before a user decides to save them at his/her desired location. In most cases, a MySQL recovery tool is created with interactive user interface, which makes it easily understandable for both technical and non-technical users.
