Shell Script to Backup your website

Often times, you need an automated script to take backup of your web application and database hosted on your Linux server. Instead of executing many commands, combine those commands into one shell script file. In this blog, we have given a shell script that will be useful to you.

This is a shell script. You have to save this as backup.sh and run this on your server.

#!/bin/bash

# options
backup_path="/var/www/BACKUP_FOLDER_PATH"
date=$(date +"%Y-%m-%d_%H-%M")

# Set default file permissions
cd $backup_path
mkdir $date

#Take website code backup
tar cvzf $backup_path/$date/MY_WEBSITE_CONTENT.tar.gz /var/www/MY_WEBSITE_PATH/

#DB Backup
user="ROOT_OR EQUIVALENT_USER_NAME"
password="PASSWORD_GOES_HERE"
host="MYSQL_HOST_NAME"
db_name="MY_WEBSITE_DATABASE_NAME" 
mysqldump --user=$user --password=$password --host=$host $db_name >$backup_path/$date/$db_name.sql

#combine .sql and website content into one tar ball
tar cvzf $date.tar.gz $date

# clean up folder
rm -rf $date

What will this script do?

This script will make a temporary folder with the name of date and time in your specified backup path. It will zip the website content using tar command. Then it will take backup of database and save it with .sql file extension. After this, the script will again zip the folder created above, containing code and database. After zipping, it will delete the temporary folder created.

After execution of this script, your website will be backed up and available as a .tar.gz file

What next?

You can either download the zip file from a file transfer software.
