Howdy. Perhaps like most of you I'm using a Lacie external hard drive to back up the contents of my internal drive. I'm running Tiger 10.4.11 and using the software that came with the Lacie hard drive. What i would like to know is there any way that a back up can be made of hard drive contents that doesn't write the same contents as previously backed up? In other words not having multiples of the same documents etc. that have been backed up at different times if they are unchanged or have been updated?
