MySQL Backup Setup Script

Overview

This repository contains a bash script (setup_mysql_backup.sh) that automates the process of setting up MySQL database backups. The script creates or updates a backup script (my_sql_backup.sh) and configures it to run automatically using cron jobs.

Features

• Interactive setup process
• Configures MySQL binary logging
• Creates a backup script for full and incremental backups
• Supports daily or weekly backup schedules
• Allows custom backup times
• Updates existing backup scripts with new settings

Requirements

• Bash shell
• MySQL server
• Sudo privileges (for modifying MySQL configuration)

Usage

1. Clone this repository:

   git clone https://github.com/datagram1/mysql_incremental_backup.git
   cd mysql_incremental_backup
   

2. Make the script executable:

   chmod +x setup_mysql_backup.sh
   

3. Run the script:

   sudo ./setup_mysql_backup.sh
   

4. Follow the prompts to enter:

   • MySQL username
   • MySQL password
   • Backup directory path
   • Backup frequency (Daily/Weekly)
   • Day of the week for backups (if weekly)
   • Backup time (HH:MM in 24-hour format)

How It Works

1. The script first prompts for necessary information.
2. It then checks for and creates (if necessary) the my_sql_backup.sh script.
3. The MySQL configuration file is checked and updated to enable binary logging.
4. A cron job is set up to run the backup script according to the specified schedule.

Customization

The my_sql_backup.sh script created by this setup performs both full and incremental backups. You can modify this script to add additional functionality, such as:

• Compression of backup files
• Uploading backups to remote storage
• Backup rotation or deletion of old backups
