Is this first Windows based contender to RSYNC?
If you are working in the IT industry and have ever had to deal with large singular files or very large datasets, then the chances are that you have come across a Linux based program called RSYNC. RSYNC is small utility that was developed by two engineers (Andrew Tridgell and Paul Mackerras) and announced back in 1996. The tool is used to copy files between two systems over an SSH or stunnel.
