we have two Master Clustered Servers using Microsoft Cluster Service and having four media server everything is working smoothly, now want to impleent DR site that may have one master server that will be add to the existing Cluster Domain because both sites are locally connected on fiber, media servers on the DR site will be connected to another robot and will backup DR servers, so i just wanted to know that may i have to buy some other licenses for netbackup or i can use the existing licenses. topology daigram is attached for reference.
