In this article, we are going to cover the ways through which you can repair a corrupted MySQL database. It is mainly seen that the chances of data corruption on large traffic database servers are on the higher side. This is either result of hard disk or network failures.
Talking about the recovery process of deleted or corrupted MySQL databases, it’s an impossible job until and unless you don’t know the right approach to get it done. Therefore, it is essential to have a backup of the MySQL database before you try to repair it or recover corrupt data. For that, you need to have a thorough approach to MySQL commands.

Now, we will cover some of the essential practical methods that would help you backup and restore your lost MySQL databases.
How to backup with the help of the mysqldump command?
If we talk about the mysqldump command, it is beneficial for dumping the database with the help of SQL statements. The following syntax helps back up a MySQL database:
Mysqldump –u[user] -p [database_name] > [filename].sql
In the command given above, the username is specified by ‘user’, the file path by ‘database_name’, and the “greater than” symbol ‘>’ specifies the output characteristic. Moreover, by using this command, a MySQL database can be backed up easily. However, in case you want to back up the database management system altogether, you need to follow the corresponding command-
Mysqldump -all-databases -single-transaction -quick -look-tables=false>full-backup-$(date +%F).sql -u root-p
