If you have earlier Historian data to include, you can use Historian Agent to backfill it to CONNECT.
To Backfill Historian data to CONNECT:
-
Select Backfill in the sidebar. The Backfill tab opens.
-
Confirm that the Replication Status is Active. If publishing is not active, see Start and stop transferring data to CONNECT to activate replication to CONNECT.
-
In the Time interval start field, type a start date or select the calendar icon and choose a start data using your mouse.
-
In the Time interval end field, type an end date or select the calendar icon and choose a start date using your mouse.
-
Select Start. Historian Agent begins backfilling your data. The Last backfill result field displays a progress bar, percentage, an estimate of time remaining, and the data remaining in blocks and bytes.
Note: A backfill job is a one time procedure. If you insert Value, Time, Quality (VTQ) data during a backfill job or after the backfill was completed, you need to redo the backfill in order to pick up the inserted VTQ data.
