Create Synchronicity (Version: 5.2.1 tested for this review) is a very capable backup tool, it can synchronize and mirror folder structures. Creating a profile comes first along with choosing source and destination folders. The type of backup or synchronization can then be chosen and file types included or excluded, with regex support, if necessary. ‘Propagate Updates’ will differentiate between files updated and only those added or deleted. The Strict file time comparison check forces Create Synchronicity to check modified dates to the second so as to not miss often updated files.
Right clicking on the profile name brings up options
