For what I was concerned, I had troubles with Amanda's balance in the following scenario: 1) I was using hardware compression 2) I was adding new DLE every days. After a few weeks adding DLE Amanda's load balancing became awfull. Then I ran Amanda with software compression once and everything went back to normal.
