Each tape will be different depending on what media is written to! Media
Lists I think may show you what is written to the tape .... But Netbackup
will only chuck data onto the tape until it sees it is full

Yes, I know. I'm not looking for an exact number. I don't know how LTO tapes
exactly work, but I suppose that the tape is written now until a certain
"position". If the tape is 609 meter long, it might be written up to 550
meters, which would be about 90%. Or is that assumption completely off?
