For successfully and safely running of a Website, there are many points which need to be considered. But one which require more attention is a backup of your website files and database. If you have a full backup of your website/blog you can again recover your website in minutes, if your website has been hacked or compromised.
So, it is always advisable to take regular backup of your website. In this tutorial I will tell you how to backup your all websites/blogs or any particular website using a Cron Job in cPanel. A website can be WordPress, Joomla, Drupal, HTML, or any other which you have hosted.
Every hosting company gives your backup facility using their backup wizard but none of them take 100% guarantee to restore your website when required, so taking manual backup yourself is a good option and choice. Logging into your hosting control panel and taking manual backup can become a tough job if you are taking backups on hourly or daily basis.
Thus to solve this problem and making an automatic backup process in cPanel, we can use Cron jobs.

Prerequisite for Backup Cron Job
I. Go to root (parent directory) of your hosting and create a folder called backup or whatever you want. Here for this tutorial I have created “backup_t2b” folder to take backup of Tech2Blog.com.
II. Create another folder called “script” and create a blank file in it called bck.sh. Now edit this blank file and paste below code in it and save it (.sh is extension for script file).
# Backup Script by Tech2Blog.com
tar cfz ~/backup_t2b/bck_$NOW.tar.gz ~/public_html/yourblog.com
You can also copy above code in notepad file and can upload it to your hosting using ftp or control panel. The above code will save your backup data in backup folder which you have created and will save it according to date in zip format.
At place of “yourblog.com” enter your domain name. You can also take full backup of every website in your hosting account by using below modified script.
# Backup Script by Tech2Blog.com
tar cfz ~/backup_t2b/bck_$NOW.tar.gz ~/public_html
Use above script only if you have unlimited web space in your hosting account. Some of good hosting provide which gives unlimited space are Bluehost and Hostgator.
Note: Don’t forget to give execute permission to this script file. You can set your script permission to 0755.
