Macrium Reflect Free v8.0.7783
I create new Differential images weekly and, for the first time today I saw that the created Diff image is smaller than the previous Diff image of 1-week ago? I have been using my computer every day and I understood that Differential images always increased in size as time went on due to more changes happening relative to the original 'Full' backup. There have been app updates as well as new user files created.
To be sure it was not a one-off anomaly I created a second Diff image and it was the same? I checked the MR logs in case I had made a mistake but I hadn't. See photo of my image records.
I did not think this was possible since there have been more changes in the 7-day period in-between compared with the Full image.
Has anyone else had this happen? Can anyone explain how this might have happened?
