Installing PC/Server Backup CentOS

Installation procedure

To add the Acronis Backup modules to Linux kernel, setup program needs the following Linux packages:

  • Package for building kernel modules. Package version must match kernel version.
  • GNU Compiler Collection (GCC) compiler system. GCC version must be the one with which the kernel was compiled.
  • Make tool.

Are the required packages already installed?

  1. Run the following command to find out the kernel version and the required GCC version:
    cat /proc/version
  2. Run the following command to check whether the Make tool and the GCC compiler are installed:
    make -v

    gcc –v
    Compare the version of gcc with information from cat /proc/version command
  3. Check whether the appropriate version of the packages for building kernel modules is installed:
    In Red Hat Enterprise Linux, CentOS, and Fedora, run the following command:
    yum list installed | grep kernel-devel

    In Ubuntu, run the following commands:
    dpkg --get-selections | grep linux-headers

    dpkg --get-selections | grep linux-image
    In either case, ensure that the package versions are the same as in Linux version in step 1.


The following table lists how to install the required packages in various Linux distributions.
