approximative size for a binary mirror?

[Mihamina Rakotomandimby]

Hi all,

I would like to locally mirror:

- oneiric main restricted universe multiverse
- oneiric-updates main restricted universe multiverse
- oneiric-security main restricted universe multiverse

According to your experience, how much space should I clear?
Only for binary. "deb-src" will pull from official mirrors per-need.

I have about 100GB free on a box, if more is needed I should consider 
buying an external USB drive.

I want to locally mirror because of bandwidth concerns (numbers of 
machines to keep up to date and limited internet bandwidth), using 
apt-mirror (I'd choosed it over debmirror).

Thank you for your help.
