This is useful when: + +* You need to reprocess historical data without activating the regular DAG schedule +* The data source is not available for regular runs +* You want to avoid unnecessary computation and logs from scheduled triggers + +When you create a backfill on a paused DAG, only the backfill runs will execute—the DAG remains paused and will not be triggered by its regular schedule. + +**Via UI**: When creating a backfill for a paused DAG, you can: + +- **Check "Unpause on trigger"**: This will unpause the DAG before running the backfill (and regular schedules will resume) +- **Uncheck "Unpause on trigger"** (default): The backfill will run but the DAG stays paused Review Comment: Did you actually test this ?
