I want to be able to backup a large list of files to another hard drive automatically every night. They are large ISO files that will change only occasionally. One copy of the file is on a Windows box, and the other copy is on a NAS. I like the idea of using Rsync, or DeltaCopy so if there are only a few changes it does not have copy over the entire file. However since the NAS is not capable of running the Rsync sever software I am uncertain how to do this. What’s the best way to automate this process and keep the bandwidth down to a minimum?
