Tyc03,
If your query is about the backup after your laptop format, then I may have the answer.
I am fairly certain that the iTunes architecture is the same for both Mac and PC, so if you have previously backed up your iPod Touch, that same backup would reside in the iTunes folder. I hope you did copy out, or backed up this iTunes folder before formatting your PC, otherwise, it is gone forever.
Your apps,
if they are legit, and purchased from iTunes AppStore, are all redownloadable, all you need to do is sign in to your iTunes account, and click-to-purchase the same apps again. iTunes will then come back saying that you have already purchased the app, and ask if you want to download it again. Click Yes to that. If your apps/games are all obtained via illegal means, a.k.a pirated, then I'm glad they are gone.
On a Mac, it is practically a worryless experience, since Time Machine will have done its daily backups, and a simple restore from Time Machine would reinstate these apps back again to its original location.
