Like a windows machine, if it's a installed game, it will save it's game to it's install directory or in My Documents.

I have astroware casino (blackjack is kind of cool sometimes), it creates a folder in My documents, so I use PIM backup to backup all my contacts and select files, like my save games, when I do a new build, I just install the apps/games, then restore the files, and exactly where I was before with all my personal data.
