Installing Symantec Backup Exec Agent for Linux

Symantec Backup Exec Linux/Unix agent is called RALUS which stands for Remote Agent for Linux and Unix Servers. I obtained my RALUS installation from official Symantec CDs. If you don’t have them you probably can download them from Symantec web site. Here is the sequence:

  1. Mount CD or iso image to your Linux host.
  2. Run ./installralus script and follow instructions. I use defaults. The only thing you should enter is Media Server IP address. Installation script add itself to rc*.d levels automatically.
  3. After installations is completed create backup user, add it to beoper group and set its password: # useradd backup -c “User for Symantec Backup Exec”;  # usermod -G beoper backup; # passwd backup.
  4. Start BE agent manually for the first time: # /etc/init.d/VRTSralus.init start

That’s it. Now you can see your server under Linux/Unix Servers section when creating backup job.

Add #1: If agent doesn’t start and you get an error with libstdc++.so.5 missing in /var/VRTSralus/beremote.service.log then install compat-libstdc++-33.

Add #2: If you have active firewall then you need to open additional ports. For me it was tcp 10000-10200. It’s 10000 plus port range you can find on media server in Tools->Options->Network and Security tab. For CentOS firewall rule would be:

-A RH-Firewall-1-INPUT -m tcp -p tcp -s media_server_ip –dport 10000:10200 -j ACCEPT

Add #3: In case you also write firewall rules to OUTPUT chain then open output tcp 10000:

-A RH-Firewall-1-OUTPUT -m tcp -p tcp -d media_server_ip –dport 10000 -j ACCEPT

If you don’t have RH-Firewall-1-OUTPUT add also:

:RH-Firewall-1-OUTPUT – [0:0]
-A OUTPUT -j RH-Firewall-1-OUTPUT

I leave possibility of me being wrong, but SBE documentation says:

Symantec recommends having port 10000 open and available on the Backup Exec media
server as well as on the remote systems.

Additional connections from the media server to the Remote Agent will be initiated on any available port.

I understand that as both agent and media server may connect to each other’s 10000 port and additional 10001:10200 connections are initiated from medias server.
