What is the difference between an incremental and differential image?

An incremental image contains all changes that have been done since the latest incremental or full image was created. If one full image and several incremental were created, all of these images must be saved in the same folder in order to be able to restore the data. If one of incremental images or full image is deleted, there is no way to restore the set, since all images are dependent on each other.

A differential image contains all changes that have been done after the full image creation. To restore a differential image, Acronis True Image must match the differential image with the original image.
