I have an interesting situation that I need some help with. A friend of mine who lives in Alaska has a Vista system with a 320g hd and also has two 160g hd's from his old system. I suggested that he install one of the 160's inside his new machine and get an USB or Esata external case for the other. Since he is remote and I am not that familiar with Vista, so what would be the best backup software to use? (preferably free). I use Seagate Manager with my machines and like the way it handles backups because once it does the initial backup it just does incremental/differential backups, i.e. it will replace a file that has changed but will save of copy of the replaced file in a History folder. I have used Sync Toy with XP machines and was unhappy with the results. Any ideas would be appreciated.
