I have a shared folder where files are saved and/or updated in different sub folders using a third party application. I am looking for an open source program that will let me try to do an differential backup to another shared folder at preset times.
For windows most people use Robocopy, which is part of the windows server resource kit. unfourtunately its not OSS, but it is free and easy to obtain. http://burpee.smccme.edu/studenthowtos/robocopy.htm
