The iTunes or iCloud backup file is not a common file, they are not readable. So even you find the backup file, you can't get the content out of it, let alone restore to your iPhone. Well, there is another thing you need to notice. Don't sync your iPhone with iTunes after you find the data loss on your iPhone. Because iTunes only updates the backup file every time you sync with it, not to build a new backup file. So if you have synced your iPhone again, the backup file will be overwritten by the content on your iPhone, and the lost data will go forever.
