Hello All,


We have a PI to PI Interface (no failover) sending data to a PI Collective. We found that the tags in this Point Source are updating only in Primary PI Server. The secondary PI Server is not receiving the real time data. Upon checking, we found the Buffering was not enabled for this Instance and hence we enabled it. After enabling it, the Secondary PI Server is also getting real time data for that Point Source. But, we could see that there had been a gap of around 6 months where the data is not present in the Secondary PI Server. We need that historical data to be present in the Secondary too. Please suggest the way forward on this? Do we need to backfill all the data into the Secondary for all the tags?
