Step-1: Choose operating system and complete prerequisites
Prior to deploying a Centralized Data Collector, it is important to determine which operating system to use for the Data Collector. The choices are Windows or Linux.
Things to consider include:
The data protection vendors and subsystems from which you plan to collect data using the Centralized Data Collector. If you use the Data Collector to collect from other subsystems and applications, the operating system you select might need to be considered.
Have you restricted remote access to NetBackup for just non-privileged users? (The Windows Data Collector requires root access for WMI.) If you are using the latest versions of NetBackup and Flex appliances that can be configured for Multifactor Authentication and restrict remote access to non-privileged users, it is preferable to choose the Linux OS for your Centralized Data Collector, or opt for a Distributed Data Collector, as detailed in Chapter 2: Distributed Data Collector on a NetBackup Primary Server .
