The driving force is the Mgt team is familiar with NetBackup and Other Open system software that does backup. They do not understand mainframe.
I have been unsuccessful in explaining it is MORE THAN BACKUP on the mainframe. And we cannot lose HSM Data unlike NetBackup. So that is the process driving the discussion. I am concerned I cannot anticipate how much spinning disk they would need on the storage array to replace a tape appliance for tape datasets. And HSM is our biggest consumer.
