If my memory serves me right you have the bpclimagelist on the clients :

And bplist - it return files where backup exists. The command is very picky about it qualifiers.

NBU Client doesn't know about successful and unsuccessful backup jobs, they are only told what backup images exists.
If you want all the details you have to query the Netbackup Master server.
