I am experimenting with data deduplication under Server 2012. A question I have, for which I have found no answer: What happens in a situation with identically named files that are for example an identical image, but at different resolutions? Is there any part of these files that is the same, bit-for-bit, chunk-for-chunk or because they have different resolution, is every bit of each one spared? Example: if I have three directories, each named the same, and each containing a psd file with the same name but there is a 72 dpi, a 300 dpi and a 1200 dpi version respectively, does any part of these images remain the same and therefore gets replaced with only a reference? If it were to delete any of the three entirely how would I know it didn't delete the best (highest-resolution) version and keep the crappy one?
