Secure copy via skip identical

Is there any way to ensure that Dopus does a secure copy? I usually copy again over what i have already copied. if it finds identical files, i choose "skip identical". is this option based on filename alone? the reason i ask is because it might be useful to have an option that skips identical based on filename AND filesize.

Skip Identical considers the name, date and size (but not actual file contents) when deciding if two files are the same.

cheers for the info. DOpus is truly the alpha and the omega! :smiley:
