Monument scans your photos and analyzes the file data (file name, size, resolution, pixels, bytes, etc.) and assigns it a unique value. Based on this criteria, Monument will not back up photos that are exactly the same.
Note: Edited and unedited versions of the same photos are both backed up
Note: The same photo downloaded on different devices often have very minor
changes that make them unique. In this case, all copies will be backed up.
