It has been suggested by Terabyte Support that the cause of the differentials becoming large might be files somehow being moved.
Several file change monitoring tools have been suggested. I'm not familiar with any of these tools. If, in fact, the only "change" to files is moving, would any of these tools detect and or report that? Just something to maybe think about. I have no idea what the answer is.
Download FolderChangesView from Nirsoft, turn on logging, and move a file.
The file will be reported as a delete in the old location, and a create in the new location.
It won't record what a system level optimize does, but the best way to test that scenario is to not optimize before creating an image, and see if it makes a difference (using the built-in Windows optimizer, and a third-party optimize tool on my system showed minimal differences).
Download Process Monitor from Sysinternals, and set up a filter for "dfrgui.exe" (Microsoft® Drive Optimizer), and run an optimize.
Speculation is not troubleshooting.
