I am having an issue whereby we have the Symantec Backup Exec 2012 SP4 running on Windows Server 2008 R2 configured as only Media server, which has connectivity to the organization production LAN with (configured with static IP, net mask, gateway and DNS) and also the Private backup LAN (configured with separate IP and net mask). I have configured the all backups network property tab to use the dedicated private back up network and the specific IPV4 subnet, but on some systems, this does not seem to work correctly and data seems to goes over the production LAN. On the media server, under Network Adaptor Advanced Settings was manually set to Backup LAN as first priority followed by Production LAN below.
Media server has a hostname on the production LAN eg xxxnbkp01 with 10.101.x.x, which is also registered in production DNS and a totally separate private IP and hostname for the backup LAN eg xxxnbkp01-bk 10.10.1.x (backup LAN information is configured in host file on media server/client servers OS to reference host and vice versa, but not registered in DNS).
Backup policies are configured to backup clients running Windows Server 2012, serverX IP 10.101.x.x using the backup LAN hostname and IP as specified in the host files eg. client1-bk IP 192.168.x.x.
We are running the latest version of Backup Exec 2012 SP4 and anyone could do with guidance on how others may have implemented a totally dedicated private backup network. Also are there any issues encountered on best practices that need to be followed in using backup LAN. Anyone assistance would be helpful.
