There's no really easy way to do this.  People typically will have
cron make a copy of the html directory on a daily or weekly basis.

Also, another problem is that the RRD files, to maintain constant
size, for older data consolidate the data, so after X days, N
measurements are min, max or averaged into one measurement.

A CGI could be set up to view the older data, but no CGI exists
yet and it would show data with the lower resolution.

Best,
