How to Install BackupPC on Fedora CoreOS

Introduction

BackupPC is a high-performance, enterprise-grade system for backing up Linux, Unix, and Windows servers to a server's disk. Fedora CoreOS is a minimalistic operating system designed for containers and Kubernetes deployments. In this tutorial, you'll learn how to install BackupPC on Fedora CoreOS.

Prerequisites

Before we begin, ensure that you have:

A Fedora CoreOS instance running
A user account with sudo privileges

Installing BackupPC on Fedora CoreOS

BackupPC is part of the official Fedora repositories, so it can be installed using the dnf package manager. Follow these steps:

Open a terminal on your Fedora CoreOS instance and connect to it as a user with sudo privileges.
Update the package repository and packages to the latest versions:
```
sudo dnf update -y
```
Install BackupPC and its dependencies. These packages will help you to keep your system secure and up-to-date:
```
sudo dnf install backuppc -y
```

Now that BackupPC is installed, you need to configure it. BackupPC uses Apache as its web server, so you'll need to create a new virtual host configuration. Create a new file under the Apache conf directory:

sudo vim /etc/httpd/conf.d/backuppc.conf

Insert the following content into the file. Don't forget to replace the IP address with your Fedora CoreOS instance IP address:

Alias /backuppc /usr/share/backuppc/cgi-bin
<Directory /usr/share/backuppc/cgi-bin>
AllowOverride None
Require all granted
</Directory>
ScriptAlias /backuppc-admin /usr/share/backuppc/cgi-bin/BackupPC_Admin
<Directory /usr/share/backuppc/cgi-bin>
AllowOverride None
Require all granted
</Directory>

Restart Apache to apply the new configuration:
```
sudo systemctl restart httpd
```

Finally, you need to configure BackupPC itself. The configuration is located in the /etc/backuppc directory. Open the config.pl file and customize its settings:

sudo vim /etc/backuppc/config.pl

Customize the following configuration settings:

$Conf{ServerName}       = 'localhost'; # Replace with your server's hostname
$Conf{CgiURL}           = '/backuppc'; # Keep the default value
$Conf{CgiAdminUsers}    = 'admin';     # Add your username as an admin
$Conf{PingPath}         = '/usr/bin/fping'; # Keep the default value
$Conf{BackupFilesExclude} = {
   '/tmp' => [ '*.log', '*.temp', '*.swp' ],
}; # Define the files you want to exclude from your backups

Once you've finished customizing the config.pl file, save it and restart BackupPC to apply the changes:
```
sudo systemctl restart backuppc
```

Conclusion

By following these instructions, you can install BackupPC on Fedora CoreOS and configure it to your preferences. BackupPC is a powerful and dependable backup system that will help you to protect your data.
