What Is MySQL Database
A database is a structured collection of data, ranging from a simple shopping list to a vast corporate network, that can be managed using a database management system like MySQL Server, allowing for the addition, access, and processing of data stored in a computer. This makes database management systems a crucial component in computing, whether used as standalone utilities or as part of other applications, due to their ability to handle large amounts of data.
MySQL is a relational database management system (RDBMS) based on SQL, first released in 1998. It has become the world's most popular open-source database, used in various applications such as data warehousing, e-commerce, and Web databases, due to its fast performance, high reliability, ease of use, and cost savings.
The Best MySQL Database Recovery Software (Recommended)
MySQL database files typically have extensions like FRM, MYD, and MYI, with *.frm containing table definitions, *.myi being MyISAM index files, and *.myd holding table data. These files can be lost due to various reasons such as accidental deletion, formatting, partition loss, system crashes, or even virus infections, despite best efforts to prevent it.
If you're facing a MySQL data loss issue without a backup, our advice is to try data recovery software, specifically Deep Data Recovery, which can handle various data loss situations and recover the MySQL database file. It has several highlights that make it a reliable choice.

How to Recover MySQL from Binlog
The prerequisite for recovering data from Binlog is that the MySQL Binlog must be turned on. If the Binlog log is not turned on, ignore this method. You can check the MySQL configuration file if Binlog is enabled and the log location is generally in the /var/lib/mysql directory.
Step 1. log in to MySQL and use the command to view Binlog.
- # cat /etc/my.cnf
- # mysql -uroot -p
- mysql> show variables like'log_bin%';
- # ll /home/programs/mysql-5.6.26/data/mysql-bin*
Step 2. Find the wrong statement in Binlog.
The execution time of the error statement can be found in the Binlog, and the logs can be restored. Alternatively, you can skip restoring the logs and directly restore the entire Binlog. Next, open the SQL file and delete the error statement.
- # sudo mysqlbinlog --base64-output=DECODE-ROWS -v -d ids --start-datetime '2016-10-11 15:22:53' mysql-bin.000001 > /home/stack/data.sql
Step 3. Recover MySQL from Binlog
You can use the MySQL Binlog command to directly restore the Binlog log to a SQL script, and you can specify a start and end time for the restoration.
If multiple Binlog files are generated from the last backup, export them to SQL and import them into the database in order from smallest to largest, starting from the last backup time. This is recommended to be done at the same time as the backup to ensure consistency.
- # sudo mysqlbinlog --base64-output=DECODE-ROWS -v -d ids --start-datetime '2016-10-11 15:22:53' mysql-bin.000001 > /home/stack/data.sql
Step 4. Recover data to MySQL
When restoring data, you may encounter repeated data errors. To resolve this issue, use the -f parameter to ignore the errors. This will allow the restoration process to continue without being halted by the repeated errors.
- # mysql -uroot -p -f ids < data.sq
Conclusion
If you need to recover data from a MySQL database, there are two recommended methods. If you have enabled Binlog, Method 2 is suggested. Alternatively, if you don't have a backup, Method 1 is recommended. Additionally, Qiling data recovery software can also recover FRM, MYD, and MYI files, among others.
