This would have to be a semi automated process as many users don't really know much about system files etc. But the user should also have some control over the process so that they could label those files they feel are important to them, for example game and program files with registation codes. Also the ability to back up the registry separately.
Each color would give the files labelled with that color a specified priority, so when backing up on limited space the highest priority colors would be backed up first. A closing script could be written to the back up when a specified aount of disc space was allowed, thus alowing for incremental back ups of the most important and highest priority files.
