Well Smartware software says 320GB. Fist attempt it took over 24 hours to complete. Is this normal, Seems long to me.
SmartWare, and Anywhere Backup before it, seem to be set for absolute minimum priority execution. They yield to just about everything else. While there are benefits to general use of the computer for this, it does make backups excruciatingly slow. It would be nice if you could adjust the priority. I suspect that the idea is to make them unobtrusive as possible if they are set up for full-time backup.
