hi , if any one knows for a software that uploads file itself on local machine folder content update, i have been through worst of my nightmare.
i want to keep back up online as soon as i resave my file , it should also gets uplaoded to specified server, like in skydrive or mediamax or any other server.

As far as I know, there isn't any program that will monitor files in real-time and upload them to a server or back them up to somewhere, likely because anything that were to monitor all files in real-time would be a huge use of resources and would drop performance a lot. The best you'd get would be something that updated on a schedule of something like 4 times a day or even once a day as that is still going to save nearly everything in the case of a full system failure. All programs also offer an option to update out of schedule too from what I've seen.
