//MYSQL backup shell, create config.txt in the path using sample. 
//bin/config.txt.sample file


# Configurations for MySQL backup script
# Replace with the desired backup folder path
backup_folder="/path/to/backup/folder"
# Replace with the number of days to retain backups
backup_retention_days=1
# Replace with your actual database credentials
username="your_mysql_username"
password="your_mysql_password"
database="your_database_name"


//bin/mysql_backup.sh file

#!/bin/bash
# Load configuration from config.txt local
source "$(dirname "${BASH_SOURCE[0]}")/config.txt"

#load config in server
#CWD=$(pwd)
#source "${CWD}/config.txt"

# Function to perform MySQL dump
perform_backup() {
    timestamp=$(date +%Y%m%d_%H%M%S)
    backup_file="${backup_folder}/${database}_${timestamp}.sql"
    env MYSQL_PWD="${password}" mysqldump -u "${username}" "${database}" > "${backup_file}"
    echo "Backup created: ${backup_file}"
}
# Perform backup
perform_backup
# Clean up old backup files
find "${backup_folder}" -name "${database}_*.sql" -mtime "+${backup_retention_days}" -exec rm {} \;
echo "Old backups cleaned up"
