I stopped my MA and started it again and the new estimated spaces to transfer are different (I took a picture before the first attempt). Just want to make sure that’s what’s happening, and not that the backup is corrupted. Thanks.
I stopped and resumed MA 3 times. Each time the estimated space was less than the previous time. It looks as if MA does indeed store partially transferred data somewhere and then puts it all together in the end, or something to that effect.
