Andrew, I think you can get by by using only ONE RRA. If you sample tha data at 5 minute intervals and store every sample for the 2 year period there will be no need to store additional average/max values.
> RRA:AVERAGE:0.5:1:210240 \ This will be the "raw" storage of all samples for 17520 hours (730 days) > RRA:AVERAGE:0.5:6:700 \ This will give you 30 minute averages for 350 hours > RRA:AVERAGE:0.5:24:775 \ ...and 2 hour averages for 1550 hours > RRA:AVERAGE:0.5:288:797 \ ...and 24 hour averages for 19128 hours (797 days) Only this last one will cover a longer period than the raw 5-minute step RRA. If you increase the 5-minute step RRA to cover 797 days (if that's what you need) you will only need that ONE RRA. If you store every sample for the required period you will be able to create both AVERAGE and MAX graphs for any period up to the total RRA storage period with any resolution up to the sample/storage interval. (Although a 2-year graph with 5-minute step size will be rather wide ;->) Creating MAX or MIN RRAs will only be required when you are using the consolidation functionality to store data lass often than the sample interval but still want to keep the MAX/MIN values.
