difference between saved copy and banked copy

Hi there,
I am reading ARM architecture manual v7, part B.
In the discretion of system register banks on page 1144, it refers SPs with a term as "banked copy"; while for the SPSRs, it uses "saved copy".
Is there a difference? I mean on the implementation of the micro-architecture.
Thanks in advance!
