Download the Free MySQL Recovery Tool to Recover Your MySQL Database

2 Ways to Recover MySQL Database Files (with Pictures) 1. Method 1: Using MySQL's Built-In Backup and Restoration Tools 1.1. Create a Backup of the MySQL Database - Connect to the MySQL Server: Use a command-line interface or a tool like phpMyAdmin to access your MySQL server. - Run the `mysqldump` Command: Execute the following command, replacing `` with the name of your database: ``` mysqldump -u -p > backup.sql ``` This will create a SQL dump file named "backup.sql" containing the database structure and data. 1.2. Restore the Backup - Stop the MySQL Service: Temporarily stop the MySQL server to prevent conflicts during the restore process. - Import the SQL Dump File: Use the `mysql` command-line client to import the backup into the MySQL server: ``` mysql -u -p < backup.sql ``` This command will recreate the database and its contents from the backup. 1. Method 2: Using Third-Party Recovery Tools 2.1. Choose a Recovery Tool: Research and select a reliable MySQL recovery tool, such as Stellar Repair for MySQL or Remo Repair MySQL. 2.2. Download and Install the Software: Download the chosen tool and follow the installation instructions provided by the developer. 2.3. Launch the Recovery Process - Connect to the MySQL Server: Enter the necessary details like host, username, password, and port to connect to your MySQL instance. - Scan for Damaged Files: Start the scan to locate damaged or lost MySQL database files. - Preview and Select Files: Once the scan is complete, preview the recoverable data and select the files you want to recover. - Save the Recovered Data: Choose a new location to save the recovered database files, and initiate the recovery process. Remember to always prioritize having regular backups to minimize potential data loss.

Don't worry if you've lost files or data from a MySQL database. You can perform MySQL recovery using a specialized tool or by leveraging Binary Log (Binlog).

What Is a MySQL Database? MySQL is an open-source relational database management system (RDBMS) that uses Structured Query Language (SQL). It is widely used for storing, managing, and retrieving data in web-based applications, content management systems, and e-commerce platforms. Developed by Oracle Corporation, MySQL is known for its speed, reliability, and flexibility, making it a popular choice among developers. It allows multiple users to access and manipulate data simultaneously and can be deployed on various operating systems, including Windows, Linux, and macOS.

A database is a systematically organized collection of data, which can range from a straightforward shopping list to a picture gallery or the extensive information contained within a corporate network. To manage, access, and manipulate data stored within a computer database, you require a Database Management System (DBMS) such as MySQL Server. Given that computers excel at handling large volumes of data, DBMSs hold a pivotal position in computing, functioning independently or as integral components of other applications.

MySQL is a Relational Database Management System (RDBMS) built upon SQL (Structured Query Language). Initially launched in January 1998, MySQL currently forms a part of the product suite of parent company MySQL AB, which includes database servers and development tools. It finds application across a broad spectrum, such as data warehousing, e-commerce, web databases, logging applications, and distributed systems. Owing to its rapid performance, high reliability, user-friendly interface, and substantial cost efficiency, it has now become the world's most popular open-source database.

The Best MySQL Database Recovery Software (Recommended)

MySQL database files typically have extensions such as .FRM, .MYD, and .MYI. The .FRM files store table definitions, .MYI files represent MyISAM index files, and .MYD files contain the actual table data. Like any other data, MySQL files can be lost due to accidental deletion, unintentional formatting, partition loss, system crashes, or virus infections. Despite your best efforts to prevent it, data loss incidents can still occur.

Next, what if you need to recover MySQL data when the issue arises but you don't have a backup? In this case, we suggest trying out data recovery software. We recommend using the tool Data Recovery Wizard. It is capable of handling various data loss scenarios and retrieving the MySQL database file from them. Additionally, it boasts several notable features:

How to Recover MySQL Using MySQL Data Recovery Tool

Download this hard disk data recovery software and retrieve your lost MySQL data as soon as possible. Launch the software and proceed with the following simple steps to recover your missing MySQL files.

Step 1. Run the Data Recovery Wizard tool on your computer. Select the drive where you lost your files and click "Scan". If your lost files were on an external storage device, first connect it to your computer.

Step 2. The software will promptly scan the deleted files and subsequently conduct a deep scan to locate additional lost files. Upon completion of the scan, you can utilize the "Filter" option to swiftly filter specific file types.

Step 3. Click the "Preview" button or double-click on a file to view a full preview. Lastly, select the desired files, click "Recover," and choose another safe location to save all the files simultaneously.

If you have other data loss issues, you can also download this MySQL file recovery software to effortlessly retrieve pictures, videos, and documents with just a few clicks.

How to Recover MySQL from Binary Log (Binlog)

The prerequisite for recovering data from Binlog is that the MySQL Binlog must be enabled. If Binlog logging is not enabled, disregard this method. You can check the MySQL configuration file to verify if Binlog is activated. The log files are typically located in the /var/lib/mysql directory.

Step 1. Log in to MySQL and use the command to view the Binlog.

1. # cat /etc/my.cnf
2. # mysql -uroot -p
3. mysql> show variables like 'log_bin%';
4. # ll /home/programs/mysql-5.6.26/data/mysql-bin*

Step 2. Locate the incorrect statement in the Binlog.

You can locate the execution time of the erroneous statement in the Binlog and restore the logs up to that point. Alternatively, you can skip this step and directly restore the entire Binlog. After that, open the SQL file and remove the erroneous statement.

Run the following command: ```bash # sudo mysqlbinlog --base64-output=DECODE-ROWS -v -d ids --start-datetime '2016-10-11 15:22:53' mysql-bin.000001 > /home/stack/data.sql ``` This command decodes base64-encoded rows, outputs verbosely, and extracts binlog events from the `mysql-bin.000001` file for the `ids` database starting from the datetime '2016-10-11 15:22:53'. The result is then saved to the file `/home/stack/data.sql`.

Step 3. Recover MySQL from Binlog

Use the MySQL Binlog command to directly restore the Binlog log to an SQL script, and you can specify the start and end time.

If multiple Binlog files have been generated since the last backup (it is recommended to update the Binlog files simultaneously with the backup) up until the recovery point, export them to SQL and then import them into the database in chronological order, starting from the smallest file to the largest.

Run the following command: ```bash # sudo mysqlbinlog --base64-output=DECODE-ROWS -v -d ids --start-datetime '2016-10-11 15:22:53' mysql-bin.000001 > /home/stack/data.sql ``` This command decodes base64-encoded rows, outputs verbose information, reads the binary log file `mysql-bin.000001` for the `ids` database starting from the datetime '2016-10-11 15:22:53', and writes the output to the file `/home/stack/data.sql`.

Translation:

Step 4. Restore data to MySQL

When restoring data, there might be duplicate data errors. It is recommended to use the -f parameter to disregard them.

• # mysql -uroot -p -f ids < data.sql

Conclusion

That's all about the MySQL database. If you have enabled Binlog, Method 2, as referenced in Part 2, is recommended. If you have no backup available, Method 1, as referenced in Part 1, is suggested. Data recovery software can help restore FRM, MYD, MYI files, and more.
