Install and verify Relax-and-Recover for Linux BMR backups

Beginning with version 8.83 of the 64-bit Linux Agent, the Linux Agent can create Bare Metal Restore (BMR) backups for restoring entire Linux systems.

For BMR backup support with Linux Agent 8.90 or later, Relax-and-Recover (http://relax-and-recover.org/) must be installed on the Linux system. The required Relax-and-Recover (ReaR) version depends on the Linux version on the system. For more information, see Bare Metal Restore Requirements in the Linux Agent release notes.

If the required Relax-and-Recover version is installed on a Linux system, you can enable BMR backups when you install the Agent on the system. See Install the Linux Agent. You can also enable BMR backups by running a script after the Agent is installed. You must also run this script if you reinstall Relax-and-Recover or change its installation path after enabling BMR backups with the Linux Agent. See Register the Linux Agent with Relax-and-Recover and enable BMR backups.

When you enable Linux Agent BMR backups, Relax-and-Recover is configured for use with the Agent. If Relax-and-Recover is installed on a server for another use, you can install a second copy of the tool in a different location to avoid overwriting existing settings. When installing the Linux Agent, you can enter the Relax-and-Recover location for the Agent to use.

If you uninstall Relax-and-Recover after enabling BMR backups for a Linux Agent, non-BMR backups will continue to work.

To install and verify Relax-and-Recover for Linux BMR backups:

  1. Download and install Relax-and-Recover on the Linux system.

    For the required Relax-and-Recover version, see Bare Metal Restore Requirements in the Linux Agent release notes. For the required Relax-and-Recover version, see Bare Metal Restore Requirements in the Linux Agent release notes.

    For installation instructions, see Relax-and-Recover documentation: https://relax-and-recover.org/rear-user-guide/basics/getting-started.html#installation

  2. Change to the folder where Relax-and-Recover (rear) is installed (/usr/sbin/rear, by default). Check the installed ReaR version by running the following command:

    rear -V

  3. Verify that the installation was successful by running the following command:

    rear -D -v mkrescue

    If the installation was successful, a rescue .iso file is created in /var/lib/rear/output.

    If a rescue .iso file was not created, check the log to determine whether a dependency is missing. By default, the log is located in /var/log/rear. For Relax-and-Recover support, go to http://relax-and-recover.org/support/.
