I have a new computer build where I have Win 7 Pro 64-bit installed on a SSD. Then I have a pair of 1TB drives that I setup as mirroring drives in Disc Management. I proceeded to setup my windows backup to the mirrored drive, but it is giving me the warning: When restoring a system image from this volume, the disks on your computer cannot be formatted to match the layout of the disks in the backup. To have full restore functionality, select a volume on basic disk as our backup location. I am not really sure I even need a backup for the SSD... it is a small 64GB drive strictly for the OS and surfing the net... minor games (wife card games, etc.)... and a few other minor things. I mirrored the 1TB drives because they are going to be our music server on our network for our laptops... as well as we planned to backup our laptops to the 1TB drive. I figured I would mirror the 1TB in case one crashed we would have the backup. A backup of the backup, so to speak. However, if I am having issues with not being able to setup windows backup on these from this computer, I assume I will run into the same issues with the laptop backups. Is there no way to use windows backup to a mirrored drive? I don't understand why that would be an issue. Thanks!
