Iphone backup crisis! Huge emergency?

My dad accidentally backed up my iphone to his iphone (all my OLD photos from years ago) and it replaced everything and all his BUSINESS contacts by the thousands with nothing and deleted everything. How will he get everything back? Will he get fired?

You need to use a data recovery software for getting them back. Here is a good one.
