cwRsync

cwRsync is a repackaging of the Rsync Windows application that comes with a client GUI (Graphical User Interface) and was developed to help advanced computer users perform fast remote file backup operations and also synchronize various sets of data in a convenient manner.

The original Rsync application makes use of its own Rsync algorithm that provides its users with a quick way of synchronizing multiple files at once. The way it does that is that it sends only the file differences between the recipients, without both file sets being available at one end before starting the operation.

This might sound downright impossible, since the diff calculations between multiple files requires local access to all of the documents most of the times.

Normally, Rsync makes use of the SSH cryptographic network protocol whenever it attempts communication. More so, no special privileges are required to install it on the target computer, but it requires that the host has a functional SSH system. It can also listen on a socket by being used in "daemon mode."

This "daemon mode" we mentioned above is more often used in the public distribution of files, despite the fact that access control and authentication are highly available.
