While this is a feature not present yet, but on the TODO file of urpmi-proxy:

I've been thinking along these lines:

1) delete older versions of the same file in the same directories
2) give a configurable max size and delete the older files if the size is 
reached
3) give a configurable time limit and delete all files older than this one (in a 
cronjob)

that being said, there are a couple of things you can do:
A) do a find with a time limit and remove the older files
B) rsync with a mirror (with --delete option)
C) rsync with a mirror (but find some option to only delete the removed files 
and nothing else)

for A) i likely can make a quick shell script to do that, but i think rsyncing 
with could be the quickest way...

which would you prefer?
