I am a photographer and archive my images on a NAS (LaCie Networkspace), but as this is a single point of failure I also back my images up to an external harddrive. However, when I am away from home I archive my images straight to the external hard drive.
I would like to be able to keep these devices in sync to ensure that al images are on both drives.
Looking at the "Favourite Mac software" question, I saw Carbon Copy Cloner mentioned, which unfortunately only works with HFS+ formatted drives, so I can rule that out. I have also tried LaCie's SilverKeeper software in the past, but could not get this to work correctly. As it seemed to think that there were too many errors and just stopped working each time I tried to sync.
Can anyone recommend some reliable and intuitive software for this task?
