One Last Thing...
When in comes to backup software, I cannot over-state the two total advantages of using the Microsoft Backup utility that ships with Windows:
1) you don't have to upgrade to the latest version in order to perform a restore; and
2) it can re-create the backup job from the media itself.
Let's face it, if your computer crashes, you probably don't have the directory that stores all the details about your backup jobs, allowing you to tag the job, select the files and then asks you to insert the appropriate media, etc.
The version of Microsoft's backup the shipped with Vista will actually read a disc you created with MS-Backup back in the days of DOS-3.x.
I don't know why I ever went to anything else --which I did recently, and had to purchase an upgrade before it would even re-create the backup catalog for me.
Learn from my mistake and stick with MS.
