Yeah, that's the funky part... the e-mails state which tape was written to but because nothing was written to tape and the e-mails are still marked as a success, they have no idea how to handle it.
I just logged on and looked at it through the application itself and to be honest I don't understand what happened either. Two of our backup to tape jobs didn't write anything to tape but claim success. They even identify the vbk as a file to backup but 0 files & 0 directories get written. Very strange.
We'll sort out the application access here but perhaps I will have to open a SR to figure out what happened with these two tape jobs.
