When working with Cyber Recovery starting release 19.13 and also with CyberSense starting release 8.2, you will have to configure the interface links between the CyberSense server(s) to the PowerProtect DD systems before you can analyze and copy. The interface link feature, also called "Multi Link" provides CyberSense the ability to load balance network traffic when reading data from the DD system(s) during analyze jobs.
It's mandatory to configure a DDBoost user on each CyberSense server you have for every DD system it's going to read files from, the DDBoost protocol is used to check that the connection exists and that it's stable, while Cyber Recovery will manage that and display the connectivity status.
If a DD system has more than one network interface, it's recommended to configure the DDBoost user for each network interface.
