karma Posted August 10, 2009 Report Share Posted August 10, 2009 I've turned on compression and am using it for the first time. So, in this session I backed up two drives. Each one had some compression applied (apparently). Yet at the end it says "0% compression". Why? Is this an error? Did I actually gain any benefit?
