Partial mirroring

[Kormos 'Morc' Gábor]

     Hi Everyone,

   This is probably off topic here and discussed in depth in the past, 
in which case please direct me to the right list/forum/Wiki/whatever: 
I'd like to set up a local mirror for my servers, but I only want to 
mirror the releases that we're running, not the complete archive. What 
is the best way to do this? I tried to find solutions and I came across 
apt-mirror, reprepro, debmirror and mirrorkit, but no page under the 
*ubuntu.com domain that covers this topic, only full mirroring.

   Thanks,

   Morc.
