Environment



Backup Exec 2010 R3

Backup Exec 2010 R3 Windows Remote Agents (RAWS)

Backup Exec 2010 R3 Ralus or Linux Agents


Cause



Backup Exec now uses stronger protocols to ensure secure communication between the media servers and remote agents, reducing the possibility that backup or restore operations can be compromised.  See Related Article Section below for more information.

When connecting to a remote computer from the media server, a trust relationship must be established.  To establish a trust relationship, the media server and remote computer exchange certificates so that each computer can confirm the identity of other for subsequent operations. Check the IP address for the remote computer to ensure that the remote computer is a trusted source before establishing the trust relationship. Verify the remote computer is a trusted source to establish the trust relationship with the media server.

The trust relationship between a media server and a remote computer is automatically established when the remote agent is push-installed from the media server. If the remote agent is installed using any of the following alternative deployment methods, the trust relationship is not established automatically and must be established manually:

 

  • Local installation of the agent on the remote computer from installation media. (This includes installation of the Remote Agent for Windows, the Remote Agent for Linux and Unix Servers (RALUS), and the Remote Agent for Macintosh Servers.)
  • Push-install of the remote agent from a computer that is not a media server or different media server
  • Deployment of the remote agent using Active Directory software package distribution
  • Deployment of the remote agent using third-party application deployment software
  • Deployment of the remote agent using scripts, batch files, or some other automated means

Solution



The trust relationship between the media server and a remote computer can be established manually in a number of ways:

 

A. Add the remote computer to Favorite Resources
