I upgraded my PC From Windows 7 to Windows 10 and created a backup restore point. However, I saw that the incremental backup size was huge which makes sense since this is an entirely new Windows system.
In the interest of efficiency, is it a good idea to reset my backup database via the windows registry and start over from scratch? It seems a waste to keep a backup of an old Windows system that I will never go back to. I plan to keep the old backup on a spare hard drive for the time being until I'm sure I'll never need anything from the old backup files again. I assume though not sure that I am still able to restore from this old database in the unlikely event I need to.
