how to backup my nba live?

If I use a new roster or any other patch,will the rewards in my nba live disappear or be changed?
And can somebody teach me how to backup it?I really want my own nba live.thanks!

Durantula_MVP, However,the free space of my hard disk isnt big enough to copy the whole nba live 05,so,could you tell me another way?I just want to save/backup the rewards in the "my nba live".thanks

If you don't have a space, you can't backup your game.

Durantula_MVP, but i can backup some important files,not the whole game.

If it's just your saved files you want to backup, then all you need to worry about is the NBA Live 2005 folder that's in your My Documents folder (the one that contains the saves, settings, screenshots etc folders).

Andrew, ok,it's very kind of you.thanks for your reply!
