@Pico You've already demonstrated you're not familiar with the purpose and function of VSS, thus you're reasoning for circumventing it are not really valid Learn about something before you give advice on it, else you risk giving others bad information that will be of no use.
As far as
@I Walk MY Way's problem, what happens if the disk was freshly re-imaged, if the partitions on the disk were deleted entirely and then had the images restored? We can talk software all we want to, and the validity or lack thereof of incremental, but it won't be of any help until we determine that the disk itself is not the issue. I say, delete the disk's partitions and restore them to a clean disk. Of course make sure your images are backed up first, and that you've run verification checks on the images to make sure the images themselves are not bad.
