Topic: Crash bandicoot save problem

I let my sister play on a alternative save file and I quit out of the game when she was done. So when I launched it my progress (around 70%) was overided by her save (around 45%) I think its couse I didn't change which one was my auto save. Is there any way to get my progress back (maybe a backup?)

Btw don't say "just play the game again" unless there literally is no way to get it back
