Hoping that this might prove useful for some.
It's a Windows DOS/batch script which will query all NetBackup clients and retrieve basic details such as version, and installation path, and OS type, etc.. and create a CSV file which can then be used/manipulated/filtered in MS Excel.
Save the script to its own folder, e.g.: D:\NBU-SCRIPTS\get-versions\get-versions.bat
The script does not modify or change NetBackup in anyway. It's simply a reporting/list type script.
Please read the script notes (inside the script) before using.
