For each new software release, Quest creates Agent repository packages for use on Linux machines. You must use an appropriate package manager (yum, zypper, or apt) to work with these packages. Download the appropriate package for the Linux distribution and version you want to protect.
Linux Agent packages are available for download on the Support website, QorePortal, and the Rapid Recovery License Portal . The Linux repository packages for each distribution include the release number, for clarity.
Each repository package creates a local software repository on your Linux machine, which can retrieve the files necessary to install or remove Rapid Recovery Agent.
When installing the Rapid Recovery Agent software on Linux machines that you want to protect, use the following prerequisites and guidance:
If AppAssure Agent software is currently installed on a Linux machine and you want to upgrade it to Rapid Recovery Agent to take advantage of new features, then note the following:
The following items are prerequisites for deploying Agent to Linux machines when you select Deploy Agent Software from the Protect drop-down menu. This action pushes the repository package to the selected Linux machine.
netstat -antp | grep ssh.
AppAssure Agent software used installer shell scripts to install or remove the Agent software from Linux machines. Rapid Recovery Agent is installed or removed on Linux machines using a package manager utility (such as yum, zypper or apt). The following factors apply:
NOTE: The local software repository is not related to the DVM storage repository in which Rapid Recovery backup data is saved.
(rapidrecovery-repo) locally on the Linux machine you want to protect. The software repository is used for staging files for the relevant package managers.
For each package manager, you can run the appropriate command at the command line to determine if it is configured to download Rapid Recovery packages. These commands are listed in the following table.

After configuring the newly installed Agent software on a Linux machine, you must restart the machine. Restarting ensures that the proper kernel module version is used to protect your machine.
Previous versions of the AppAssure Agent software must be removed from a Linux machine before installing the Rapid Recovery Agent version and protecting the Linux machine using the Rapid Recovery Core. This requirement applies to both online and offline installations. For more information, see Uninstalling the AppAssure Agent software from a Linux machine.
Thus, the installation process when upgrading from AppAssure to Rapid Recovery involves:
See the following important information before you begin installation of Agent software.
When you upgrade from one version of Rapid Recovery Agent to another, you must first remove the local software repository. During the installation process, a new local repository is created with the appropriate installation files. Steps are included in the topic Installing or upgrading Rapid Recovery Agent on a Linux machine specific to upgrading.
Thus, the installation process when upgrading versions of Rapid Recovery involves:
After installing Rapid Recovery Agent, configure the Agent software as described in the topic Configuring the Rapid Recovery Agent on a Linux machine.
Caution: After configuring the newly installed Agent software on a Linux machine, restart the machine. Restarting ensures that the proper kernel module version is used to protect your machine.
You must download the distribution-specific 32-bit (x86) or 64-bit installer on every Linux machine that you want to protect. You can download the installers from the Rapid Recovery License Portalat https://licenseportal.com.
Linux uses the Pluggable Authentication Module (PAM) to manage security. Once a user is authenticated through libpam, the user is only authorized to protect the machine if the user is in one of the following groups: sudo, admin, recovery, root, or wheel. For information on protecting a machine, see the section “Protecting a Machine” in the Rapid Recovery 6.3 User Guide.
There are several files required to support the Rapid Recovery Agent software on a Linux machine. For all supported Linux distributions, these files are located in the following directories:
