One way to backup you data on the outside of the firewall, and maintain security is to set up multiple masters, one inside and one outside, while still sharing a robot.

Since you can run Media Manager independent of NetBackup, I say set up two Media Manger servers, Server A as the robot control host and volume Database host, and the Server B as a slave owing a driver in the robot controlled by server A.

Now have NetBackup set up as a master on both nodes, now you have a master on both sides of your firewall, and still one storage of tapes. Now all you need are two ports to communicate through the firewall. One for VMD to manage tape assignments, and one for tldd, or tl8d or whatever to control The robot.

This reduces security holes, and makes backups and restores are easier and faster. For more security, delete the import bimary on the server on the outside of the firewall. I'm adding this link as a cross-reference to the other FAQ on backups through a firewall. How do I backup through a firewall?
