let's say you have to backup one file that is 500 mb every night. a normal file copy would copy the entire file even if a few bytes have changed. deltacopy, on the other hand, would only copy the part of file that has actually been modified. this reduces the data transfer to just a small fraction of 500 mb saving time and network bandwidth.in technical terms, deltacopy is a "windows friendly" wrapper around the rsync program, currently maintained by wayne davison. "rsync" is primarily designed for unix/linux/bsd systems. although ports are available for windows, they typically require downloading cygwin libraries and manual configuration.
