How do I create a new backup file from a backup extract?

I recently factory reset my iPhone 11 Pro Max but backed up everything before hand and then updated the phone to the latest iOS and now the backup will not work with the phone but it's not corrupted. Everything Apple suggested over the phone I'd already tried and Apple store were just as unhelpful. This backup is important as it has numerous photos and notes that hold sentimental value. I have found a few programmes that allow you extract the data from the backup which it finds no problem but I now want to put the extracted data back onto the phone in the form of a backup so it's fresh. Is there anyway of doing this as I have everything even down to the settings etc. but Google isn't providing me with much hope, only how I can extract the data from the backup, not how I can then put it all back on the phone.
