i am also trying to learn the the netbackup and will appertiate if there is any simulator that you can share with me.
The earlier path that you have shared as a response to the same question raised years back is surrently not avaliable kindly help
AFAIK there is no simulator. However you can install a Master Server trial, for example in a Windows VM (steps for download are easily googleable).
Also you can "buy" Master Server instance on Amazon: https://aws.amazon.com/marketplace/pp/Veritas-Technologies-LLC-Veritas-NetBackup-for-AWS/B07N2F4PV7
However I recommend you to take part in an official NetBackup training. This is the product which is not very suitable for "self-study by clicking".
