(Assuming that you don't mind requiring ftp access...)

One of fmirror's stated design goals is to use as little RAM as
possible, and it has a much nicer inclusion/exclusion semantics than
mirror, but I couldn't get it to work here.  It kept dying with socket
problems.  This was a while back, though, so it might work now.  If it
hadn't been for that show-stopper, I would have switched.  It's syntax
made it really easy to specify things like "I want a mirror of
unstable and frozen, but only the {disks,binary}-{i386,all} stuff.  To
do the same thing in mirror syntax is a much bigger hassle.

Another tool, mirrordir on the other hand claims to make a minimal set
of changes.  It doesn't download files, devices, etc. just because
their permissions have changed, it handles these modifications itself.
It's biggest failing (as far as I can see), is that it has really
limited inclusion/exclusion mechanisms.  For example, it looks like
only one exclude-regexp is supported.

Oh, and anyone else notice that mirror's in non-free?  I was
surprised.
