Data Transfers · Scheduling transfers
Why does a scheduled transfer appear many times in the list?
Short answer: Every scheduled run is listed as its own entry so you can see the history. Remove old runs one at a time, or use Clear completed — which also stops schedules whose original entry has finished.
Each scheduled run is added as its own entry, so the list doubles as a history: you can see when each run happened, how much it moved and whether it succeeded — much like a list of past backups.
To tidy up, select an old run and click Remove, or use Clear completed to remove every finished, failed and cancelled entry at once. Be aware that Clear completed also removes a schedule's original entry and stops that schedule.
