Time travel allow BigQuery customers to query data that was updated or deleted, restore a dataset or table covering by default the last seven days. You can configure it at:
- project-level
- dataset-level BigQuery provides a fail-safe period. During the fail-safe period, deleted data is automatically retained for an additional seven days after the time travel window, so that the data is available for emergency recovery.
- You can only recover data by contacting customer care.
