However, for a 30-day RPO, you need a longer retention period. BigQuery offers table snapshots that are storage-efficient (only store changes/deltas, not full copies) and can be retained for 30 days.
Regional - to minimize cost, scheduled backups - to enable 30 days RPO (time travel only gives you 7 days)
Regional datasets are *cheaper* than *multi-regional*, which helps minimize cost. Scheduled queries can automate daily or hourly snapshots, ensuring you always have backup data within the 30-day RPO window. Time-suffixed tables allow for granular restoration to a specific date. This is a manual but cost-effective backup strategy.
