Trouble getting SQL backups to run of over private backup lan
I am having an issue whereby we have the Symantec Netbackup Appliance 5520 configured as Master & Media server, which has connectivity to the production LAN and also the Private backup LAN. I have configured the backups to use the dedicated private back up network, but on some systems, this does not seem to work correctly and data goes over the production LAN.
Master/Media has a hostname on the production LAN eg nnbumaster 10.10.x.x, which is also registered in DNS and a totally separate IP and hostane for the backup LAN eg nbumaster-bk 192.168.x.x (backup LAN information is configured in host file on master/media to reference host and vice versa, but not registered in DNS).
Policies are configured to backup client client1 IP 10.10.x.x using the backup LAN hostname and IP as specified in the host files eg. client1-bk IP 192.168.x.x.
Flat files windows backups are routing fine using this method, but SQL backup are talking over the production LAN and backing over this LAN, even though host file entries have been configured the same as the other working systems.
Can anyone advise if using the appliance as master & media is supported any are there any issues, since this something new that I am working on, but surely the principles are the same as a non appliance based Netbackup environment. We are running the latest version of Netbackup 7.5 and 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 when doing restore since client1 is the actual hostname, but in terms of the backups images, these are accessible under the backup LAN hostname client1-bk.
Anyone assistance would be helpful.
