Maybe if I can help by formulating a question. (I am not addressing your other concerns)
Multiple tape drives:
Our old library had only one drive installed. I could have added
a second one, but I could not see how amanda would use it to advantage.
Can amanda use a second (or third...) drive?
Is there any benefit?
I think the end-game concern should be related to software support....Maybe the question needs to be asked if anyone has successfully used an existing AMANDA changer module with two tape drives in a single media changer and in a single AMANDA changer configuration... If so... I want to know about it...
I would presume (hopefully I am wrong) that people who have done this modified their changer module code locally and it has not been rolled into the AMANDA source.
