Hey rafeedeen,
Hope you have already solve your problem and get back your data from the backup files. If you can't find the deleted data from your backup files, you can also try your luck using third party recovery software. This kind of recovery software can scan your iPhone or iPad to find the lost/deleted data for you and recover to your computer. You can search the "iPhone data recovery" on google or other search engine and you will get many results about it. You can just have a try. Good Luck!
