I am trying to backup two portable harddrives. One being with me and the other being at a safe location. Every once I a while I want to connect both to my pc and have the one that was at another location to sync so they are both on the same version. I just want to copy the diff and it has to run in Windows Vista.
It is actually for my dad so the easier to use the better. It can be a bit more complicated if I have to set it up once :)
