When installing the Agent software on Linux machines that you want to protect, use the following guidance. After installation is complete, configure the Agent as described in the topic Configuring the Rapid Recovery Agent on a Linux machine.
The method for installing and removing the Agent software on Linux machines has changed. As of release 6.0.1, the following factors apply:
Because the various supported Linux distributions use different package managers for online installation, the procedure for installing, upgrading, or removing Agent on any supported Linux OS depends on the package manager used. The package managers, and the Linux distributions they support, are described in the following table.
|Package Manager||Linux Distribution|
|yum||Linux distributions based on Red Hat Enterprise Linux (RHEL), including RHEL, CentOS, and Oracle Linux.|
|zypper||SUSE Linux Enterprise Server (SLES) versions 11, 12|
|apt||Linux distributions based on Debian, including Debian 7 or 8, and Ubuntu 12.04 and later|
As a one-time setup step for each Linux machine, you must configure your local software repository to point to the location where the package manager obtains Dell Rapid Recovery installation files.
After you configure a software repository on your Linux machine, the package manager is able to retrieve and install the packages needed for installation or removal of Rapid Recovery Agent software and related components, such as aamount (now called local mount), aavdisk (now called rapidrecovery-vdisk), and Mono (an open source, Ecma standard-compliant, .NET Framework-compatible tool set used for porting the Agent software to Linux platforms).
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.

Previous versions of the AppAssure Agent software must be completely removed from a Linux machine before installing the Rapid Recovery Agent version and protecting the Linux machine using the Rapid Recovery Core. This is true for online or offline installations. Removing AppAssure Agent employs the use of shell scripts. The uninstall instructions differ, depending on the Linux distribution you are using. For more information on uninstalling AppAssure Agent from a Linux machine, see Uninstalling the AppAssure Agent software from a Linux machine.
If installing Rapid Recovery Agent on a Linux machine that has never had AppAssure Agent installed, determine the appropriate package manager from the preceding table. Then follow the appropriate installation procedure.
After configuring the newly installed Agent software on a Linux machine, you must restart the machine. Restarting ensures that the proper kernel driver version is used to protect your machine.
Thus, the installation process when upgrading from AppAssure to Rapid Recovery involves:
The instructions for installing the Agent software on a Linux machine differ slightly depending on the Linux distribution you are using. For more information about preparing for and installing the Agent software for a Linux machine connected to the Internet, see the appropriate topic. You can choose from the following sections:
See the following important information before you begin installation of Agent software.
You must download the distribution-specific 32-bit or 64-bit installer on every Linux machine that you want to protect. You can download the installers from the Dell Data Protection | Rapid Recovery License Portal at https://licenseportal.com. For more information, see the Dell Data Protection | Rapid Recovery License PortalUser Guide.
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, or wheel. For information on protecting a machine, see the section “Protecting a Machine” in the Dell Data Protection | Rapid Recovery 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:
