For image backups, I have used Acronis True Image Home 2010 for Windows XP Pro and Vista. It won't backup a Linux partition, yet I would install a new Linux after major releases. Acronis has compression and archive splitting. It'll make a backup partition to put your image on or some other media such as DVD, USB HDDs, and another SATA hard drive. The Arconis 2010 is good for Vista. It works with Windows 7, but the taskbar seems to crash.
I have my music on DVD, and external hard drive. That's the only thing valuable on PC.
