I have about 8000 RRD files that I periodically need to backfill with data from other RRD files (think of a redundant measuring system). Right now, I take the "bad" RRD file, dump it, search through the XML file for the time periods I know are wrong, find any NaN values, and replace them with the values fetched for the same time out of the "good" RRD file.
With 8000 RRD files, this takes about 24 hours to do (the dump files are enormous, bordering on 10MB for some of the larger RRD files). Given that RRD files have a fixed file length, a fixed time period, and a fixed step, I'm wondering if anyone has a utility that will just let you overwrite a value in a specific time slot with another one? I don't care about the interpolation or calculations or anything. The data for a specific row is a known good value and "belongs" in that spot. Does anyone know of such a utility?
