I wrote a script a while ago to archive my .rrds to a backup directory.
I'll attach this below.
Works great for me, but naturally, YMMV. Perhaps you can use it.

        Round Robin Databases (.rrd) are created and/or updated every
        five minutes by MRTG/RRDtool. This is where our circuit usage
        data is stored.

        $0 copies the rrd files from their
        home at /var/www/html/mrtg/rrdfiles/ to /usr/local/etc/archive/
        and these files are then tarballed, gzip-ed, and deleted.

        $0 is run daily via cron.daily and
        automagically removes rrd tarballs older than 1 week.
