If I understand your question, the answer is no - not by default. Rrd aggregates / summarizes historical samples at windows you define. You MAY be able to get what you're after by tweaking: Dump Interval, Throughput Granularity, Dump Hours, Dump Days, and Dump Months in the rrd config. Once you have this set to store the raw data (unsummarized) for the time period you want, you can use the Arbitrary Graphs interface to pull it out.
Be careful. If you want to see historical data at 1min granularity for .. 30 days? 60 days? Longer? That's a LOT of samples. I do something similar with Openview NNM: I keep the 5 min samples in raw form for... 6 months or so and export summarized data for 2 years. Just keeping Octets TX/RX on an interface makes for some "big" files after 6 months. rrd will want to store this info for every host by default - which means a LOT of data. You may have to spend some time tweaking the rrd configs to get what you want. If you simply want gross interface I/O for that period, maybe another tool would be a better fit? Just something to consider.
