How to Install BackupPC on OpenBSD

This tutorial will guide you through the installation process of BackupPC on OpenBSD.

Prerequisites

Before you begin, make sure you have the following:

• OpenBSD installed and updated to the latest version.
• Superuser, or root, access.

Install BackupPC

1. Install the necessary packages with the following command:

   $ sudo pkg_add -i apache-2.4.48p1 rsync-3.2.3p2 perl-5.32.1p1 p5-Apache-Session-1.94p1 p5-Compress-Zlib-2.093p2 p5-CGI-4.50p1 p5-XML-Simple-2.25p2
   

   This will install Apache, rsync, and the necessary Perl modules.

2. Download BackupPC from the official website by running the following command:

   $ sudo ftp https://github.com/backuppc/backuppc/releases/download/4.4.0/BackupPC-4.4.0.tar.gz
   

   This will download the latest stable release of BackupPC.

3. Extract the BackupPC archive by running the following command:

   $ sudo tar -xzf BackupPC-4.4.0.tar.gz
   

   This will extract the BackupPC files to a directory called "BackupPC-4.4.0".

4. Move the BackupPC directory to the Apache document root by running the following command:

   $ sudo mv BackupPC-4.4.0 /var/www/htdocs/backuppc
   

   This will move the BackupPC files to the Apache document root directory.

5. Create a symbolic link to the BackupPC directory by running the following command:

   $ sudo ln -s /var/www/htdocs/backuppc/cgi-bin/BackupPC_Admin /var/www/cgi-bin/BackupPC_Admin
   

   This will create a symbolic link to the BackupPC_Admin file.

6. Set the appropriate permissions for the BackupPC directory by running the following command:

   $ sudo chown -R _www:_www /var/www/htdocs/backuppc
   

   This will change the owner and group of the BackupPC directory to "_www".

7. Edit the Apache configuration file by running the following command:

   $ sudo vi /etc/httpd.conf
   

   Add the following lines to the file:

   ScriptAlias /backuppc/cgi-bin/ /var/www/htdocs/backuppc/cgi-bin/
   <Directory /var/www/htdocs/backuppc>
   Options ExecCGI FollowSymLinks
   AllowOverride None
   Require all granted
   </Directory>
   

   This will configure Apache to recognize the BackupPC directory.

8. Start the Apache server by running the following command:

   $ sudo rcctl start httpd
   

   This will start the Apache server.

9. Configure BackupPC by editing the configuration files located in /usr/local/backuppc/conf/:

   • config.pl: This file contains the main BackupPC configuration options.
   • hosts: This file contains the list of hosts to be backed up.
   • pc: This file contains the individual configuration options for each host.

   Please refer to the BackupPC documentation for more information on configuring BackupPC.
