I like this thread

This is a good thread and pertinent to NetBackup administrators.
I have been asked to supply questions to hiring managers several times throughout my career.

This is a pretty telling question about basic NetBackup
8. What is the difference between a Volume Group and a Volume Pool?
15. How can we assign barcode rules?

But remember. The answers are only good when a followup question is used to get to more depth. A person could memorize the simple answers to the questions but the proff is in the followups and how the person being interviewed reacts.

I think this is an Linux

I think this is an Linux question.If you are untaring some file and you are not giving proper command at that time you will face this problem.
I think it is nothing to do with these Netbackup questions.

Thank you
