Can you start a new game and keep your old save?

[Rim Carrey]

I beat the game and want to do the story again with a new save. Will this delete my old saves?

[Carolynne]

If you make a backup of your savefiles then you can still have them.

You don't have to do any of that, just start a new game and save it under a different slot in save options in game.
