Presentation

The goal of this simple BASH script is to automate the backup of Web virtual hosts on a Web Server using a minimal set of tools.

Features

• Backup one or multiple vhosts and compress the files in a Zip archive ;
• Set a custom backup location ;
• Set a custom name for the backups ;
• Send E-Mail at the end of each step ;
• Automatically delete backups older than a custom number of days ;

The code is made so that it is easy to read and understand and can be adapted to specific use-cases.

Dependencies

• The cron job scheduler ;
• The zip CLI tool ;
• A mail transfer agent such as exim4 or sendmail ;

Installation

1. Clone this repository in you home directory
2. Move web_backup_script.sh to a dedicated directory (for example, in a .script directory, in your home directory) ;
3. Edit the file to replace the placeholders with the wanted values:

In VARIABLES, replace at:

<webdir>, <backupdir>, <recipient_email>, <keep_day>, <webfiles1> and <webfiles2>

In BACKUP CREATION & COMPRESSION, replace at:

"yourStrongPassword" with your password ;

4. Give this file execution permissions:

$ chmod 700 /path/to/the/.script/web_backup_script.sh && chown root:root /path/to/the/.script/web_backup_script.sh

5. Edit /etc/crontab and at the end, add:

00 0    1 * *   root    sh /path/to/the/.script/web_backup_script.sh

This will execute the script on the first of each month at 0:00.

# sh /path/to/the/.script/web_backup_script.sh
