im looking for some disk imaging software or backup that has the capability to only "update" the drive so to speak. basically so it doesn't take as long, like only add files that werent previously there and update files that have been changed. does anyone know of a good software for this that is freeware? i tried to use XXClone, and the first time to 100% clone it took 55 minutes for 80GB which is expected, but it has an option to use "/hyper" which they say only copies files that are new and the ones that have been edited. immediately after cloning it the first time i did it again with the "/hyper" activated, and it seems to go faster at first, but it starts to copy my movie files, which were not touched and not edited, along with all the other files that have not changed. i suppose i could do a raid mirror, but i don't want both drives to be running all the time when not necessary, i want to be able to hook up my backed up drive in time of failure only, and im only going to backup monthly or so.
