'her' is the definition.

'backing put a pound on for' is the wordplay.
'backing' shows that the letters should be reversed in order.
'put' indicates putting letters inside.
'a pound' becomes 'L' (the pound sign is based on an L).
'on for' becomes 'aon' (I can't justify this - if you can you should believe this answer much more).
'l' inserted inside 'aon' is 'alon'.
'alon' back-to-front is 'NOLA'.
