Are you ready? Let's read!
InnoDB is one of the low-level subsystems in the MySQL database management system. It is included in all standard assemblies for any Windows OS version.
The main difference from other low-level MySQL subsystems is the presence of foreign keys and a transaction mechanism. In InnoDB, data is stored in large shared files, whereas in MyISAM, a data file is created for each particular table. The data format provides reliable data storage by locking data at the row level. However, there are situations when there is a need for MySQL recovery.
Therefore, you need to know at least a few good MySQL InnoDB recovery tools.
Method 1. InnoDB recovery from a corrupted or failed disk
To do MySQL InnoDB recovery, you first need to simply restart the computer. This helps to remove errors associated with the corruption of the database, while the data remains unaffected.
You can also check the table for errors. CHECK TABLE is great for this in MEDIUM mode. If you worry that the table may be destroyed, it is better to use the function QUICK. In any case, be prepared for the fact that the table can be changed. If you have a backup copy of the database, it's time to use it. After that, you can recover data after all subsequent changes to the tables using special programs and applications. The best such application will be described below.
Method 2. InnoDB recovery with MySQL Recovery
