We have PI OPC HDA interface (Version configured, set the HR for 1 day.


While trying to recover the data gap through another History recovery Instance, we moved the existing tags to this new History recovery instance.


Data was recovered for the history period.


After recovering the older data , tags were moved to the original istance. As the history recovery parameter is set to 1 day, we assumed that the data should backfill acutomatically for the period during which history recovery was being performed.


But after checking we found that, Data was not backfilled automatically.


Please note - Interface was not restarted


Can anyone guide us on how the history recovery works in this case?
