I am trying to implement a back up system that will automatically sync with a new machine that falls within my specified criteria. An example of what I want would be any new server booting on a specific ip range would automatically download the files from my host server. I currently use Rsync for my back ups with a cron job to automate them. I have no ideas as to any tools or different possible ways to make this idea possible. Any suggestions or advice would be greatly appreciated.
