how do we tabulise the EMMDB?

This is the same person who asked for Interview questions...

Think you don't, as you then will be messing with the internal workings of netbackup.

If you want to do reporting use OpsCenter, the built-in reports in the Console or the commands maybe in some scripts.

I have moved this discussion to NetBackup forum as RealTime has been discontinued. Please try to rephrase your question? I have no idea what you are asking.
