In the back-up part a full partition/HDD backup would be great to have. This way we would be able not just only restore the important stuff, but if anything happens we can restore the whole windows.
I imagine the function this way:
1. You can create the backup in windows manually from the backup manager. You can save the files to DVD/BD/LAN/USB-storage or a specified folder (this shouldn't be the same place as where normal backups are stored).
2. If you want to restore you had to use the Recovery Disk to do it.
