This is a Node.js application that performs automatic backups of a MySQL database using the mysqldump command. The backups are saved as SQL files in a "backups" folder.

• Automatic backup of a MySQL database at regular intervals (default: every hour)
• Backup files are saved as SQL files in a designated "backups" folder
• The "backups" folder is automatically created if it does not exist
• The backup process logs information and error messages to the console

Before running the application, make sure you have the following:

• Node.js installed on your machine
• A MySQL database with connection credentials
• MySQL command-line tools installed (to use the mysqldump command)

1. Clone this repository to your local machine or download the source code.
2. Install the dependencies by running the following command in the project directory: npm install
3. Create a .env file in the project directory and set the following environment variables: DB_HOST=<MySQL host> DB_USER=<MySQL username> DB_PASSWORD=<MySQL password> DB_DATABASE=<MySQL database name>
4. Replace <MySQL host>, <MySQL username>, <MySQL password>, and <MySQL database name> with your own database connection details
5. Run the application using the following command: node index.js or npm start
6. The backup process will start, and you will see log messages indicating the progress and status of each backup operation.

• If you want to change the backup interval, modify the interval value in the setInterval function call in startBackup method of the DatabaseBackup class (specified in milliseconds).
• To specify a different backup folder path, modify the backupFolder property in the DatabaseBackup class constructor.
