I have been foolish, or lucky, or both. I have never implemented any kind of personal regular backup for my data- or my operating systems. I will be receiving a new riMac this month. I will need to run either bootcamp or parallels on it to have access to Revit and AutoCAD. I will likely start with parallels and if I am happy with it, won't switch to bootcamp. But I have yet to see any good recommendations or topics on how people are backing up these split OS systems. Advice and recommendations appreciated!
