Backfilling replication set business class from archive

When data is purged, it is removed from the rowstore but not automatically removed from Data Lake or Columnar.
  • Data Lake: Purged data remains unless the data is explicitly cleared from the Data Lake table. In some cases, you may need to clear the table and reload it.
  • Columnar: Purged data remains unless a replication set business class is reset. When the replication set business class is reset, all Columnar records are deleted, and the next replication reloads only the active records from the rowstore.

In both scenarios, when you reset the Columnar replication set or clear the Data Lake after a purge, you can run the backfill action to reload archived data into a replication set business class. This action is available for all output types, and you must run it after a reset followed by a full replication. Only data purged before the reset is backfilled.

You can backfill a replication set business class only when these conditions are met:
  • The business class is archivable.
  • EnableArchiving and EnableArchivable parameters are enabled.
  • The business class is active and has both create and update stamps.
  • The flatten columnar hierarchy is not used.
  • No pending condition changes that require replication.
  • The replication set has been reset.
  • A full replication has been performed following the reset of the replication set.
  1. Open the replication set business class to backfill.
  2. Select More Actions > Backfill Archive Data.
  3. To verify that the data is backfilled, confirm that the replication file contains the non-columnar records that are purged before the reset, and that the purged data is reloaded to the columnar list for columnar records.
