Laura,
We, too, were fighting with the crummy built-in backup that Microsoft includes with Windows. I just demoed and then purchased Retrospect Single Server 6.5 for Windows. They have lots of versions available. You can check it out at
www.dantz.com We looked at Veritas Backup Exec, which is supposed to be very good, but then heard that it was a nightmare to set up. Retrospect sets up very easily.
Feel free to email me privately if you have specific questions that I could help you with.
