This guide explains how to prepare your server and install the Acronis Backup Agent for Swiss Backup on AlmaLinux 9.

Install the Acronis CyberProtect Agent

1. System requirements

• Use an account with root privileges.
• Internet access required for uploads and downloads.
• Available disk space: approximately 2 GB.

2. System Preparation

1. Switch to the root user:

   # Switch to root user
   sudo -i

2. Update the DNF metadata cache:

   # Refresh DNF metadata cache
   dnf -y makecache

3. Check the current kernel and GCC versions:

   # Check current kernel and GCC version
   cat /proc/version

   If the kernel version does not match the available kernel-devel package, an update will be necessary in the next step.

4. Install the build tool (make):

   # Install make utility
   dnf install -y make
   # Verify installation
   make -v | head -n 1

5. Install the GCC compiler:

   # Install GCC compiler
   dnf install -y gcc
   # Verify version (should match the one in /proc/version)
   gcc -dumpfullversion

6. Install the latest kernel and its headers (kernel-devel):

   # List available versions
   dnf list kernel kernel-devel --showduplicates | sort -r
   # Install latest kernel and headers
   dnf install -y kernel kernel-devel

7. Restart the server to load the new kernel:

   # Reboot the system
   systemctl reboot

   After the restart, reconnect and switch back to root (sudo -i).

8. Confirm that all required tools are present:

   # Final environment check
   uname -r
   rpm -qa | grep ^kernel-devel
   make -v | head -n 1
   gcc -dumpfullversion
   perl -v | head -n 2
