Keeping and up-to-date mirror

[AmericanAqualung]

Hi,
I've just been setting up a mirror for our linux cluster here at Haverford (the nodes don't have open internet access) using Debmirror following the great guide here:
https://help.ubuntu.com/community/Debmirror

My only question is, does anyone know how the mirror's packages stay up-to-date? Will it do this automatically when I run apt-get updates/etc on the mirror, do I need to reexecute the script, ...?

Thanks,
Andy O'Hara

I am bumping this thread because I have the same, exact question. The documentation does not mention how to keep the mirror up to date.

Can anyone shed some light?

Regards
