iphone backup question

Unique question I can't seem to find any answer for. So my mom has 2 iPhones one for work and one for personal. She has backed up her personal phone to her computer multiple times but never her work phone. So today she plugged in the work phone to pull the pics off of it on to her computer and as per default iTunes lunched. So rather then click on start as new iPhone (this was the first time this phone was plugged into her computer) she accidentally clicked on restore from backup. Well you can guess now her work phone has all her stuff from her personal phone. Is there anything she can do to revert the phone back or is she out of luck?

 

That's what I thought. After talking to her no luck so now she is juts going to restore the phone and start over. Lesson learned and she is going to set up iCloud right away.
