Restore or Resynchronize Historian Archive Files

Under certain circumstances, you may want to restore tag and alarm and event data to Historian. This may be after an unplanned shutdown, or you may need to retrieve data from an old, inactive archive. You can restore only time-based archives.

Warning: Never restore an archive to a production Historian server without a current archive already online.

CAUTION: Restoring an archive is a resource-intensive operation and should be scheduled for non-peak usage times.

If the Archive files in the mirror environment are not synchronized, manually synchronize the archive files from one node to another node by using the Resync Archive option.
