Hello @SSchmidt
The data we are writing to the tape is not stored on the MA at all. It is going to write random data in chunk sizes to the tape that has no relation to anything.
In regards to settings the only one you would edit is block size and you can read more about it here:

I would recommend just using the default if i were you.
If you are having performance problems with your Aux copy jobs you might want to look into multiplexing for the tape library. Please read more here:
