Sync toy for external drive back up

    Question

  • I want to use this to back up photos from one external drive to another external drive.

    I want the source drive (left drive) to be compared to target (back up drive) (right drive) and any new images or changes to images on source drive to be copied or updated on back up drive. 

    Where confusion comes in is the target drive (drive backing up to) has photos on it that are not on source drive.  Want to make sure those images are not removed from the target drive.  If I chose "contribute" will that add new and make changes but not remove images on back up drive that are not on source drive (drive BEING backed up).
