Advice for dated archives

Summary: Looking for a smooth way to allow rsyncing of mail and news
to generate cumulative archives, but cut off a specified
date, and begin a new archive that contains nothing of the
That might have sounded kind of confusing, but here's my setup: I
routinely rsync my ~/Mail ~/News (news is downloaded usenet) to
cumulative archives so that as expiration/expunge etc occur in ~/Mail
~/News I have the current working(trimmed down) set but also a large
archive of everthing since (whenever). /some/archive/Mail
As you may imagine the archives eventually grow unusably large. I'd
like to figure out a cool accurate way to continue this setup but
generate a new set of archives (keeping the old) with dated names.
Trouble is how to sync the current trimmed down set with the new
archive, so that none of the messages in current ~/Mail(News) that
are already in the previous archive, get rsynced to the new one. So
I have a clean break with no duplication.
Something similar to the `newer' option to find command would be nice.
So that one day I could just tell rsync to move stuff to the new
archive but not if its older than DATE.
Any ideas how to accomplish this with the least huffing and puffing?
I did try some experiments with --compare-dest=DIR but didn't really
see how to accomplish the above goal with that.
