It has been my "habit" to use True Image 9.0(build 3854) to backup my hard drives at least twice a month (to an external hard drive). I'm trying out Diskeeper 11.0, to keep my drives defragged. It has an auto-defrag mode. --------------- Is it OK to leave auto-defrag on, while Acronis operates; or should auto-defrag be disabled prior to starting Acronis Imaging? --------- Any advantage to upgrading to Acronis 10., given that 9.0 works just fine on my systems? Advice anyone?
