BigQuery 会自动跨 zones/regions 复制数据吗？
Does BigQuery automatically replicate data across zones/regions?
我正在通读 BigQuery 文档，但对下面引用的观点感到困惑。
来源：Google Doc
BigQuery transparently and automatically provides highly durable,
replicated storage in multiple locations and high availability with no
extra charge and no additional setup.

BigQuery does not automatically provide a backup or replica of your data in
another geographic region. You can create cross-region dataset copies
to enhance your disaster recovery strategy.
- BigQuery 是否自动复制 跨 zones/regions 的数据？
- 对于长期数据存储，给定 Big Table、Big Query 和 Regional Persistent Disk 选项，是最好使用 Regional Persistent Disk 跨不同地理位置自动复制数据？
- 是的，BigQuery 自动跨 zones/regions 复制数据。
的一部分
In either case, BigQuery automatically stores copies of your data in two different Google Cloud zones within the selected location.
但是当您阅读时，我认为您遗漏了一些信息。它提到了一个严重的区域失败。
什么是硬区域故障？正如Google Doc描述的那样，
Hard failure is an operational deficiency where hardware is destroyed. Hard failures are more severe than soft failures. Hard failure examples include damage from floods, terrorist attacks, earthquakes, and hurricanes.
例如，在 Asia-east1（台湾），地震发生相当频繁，如果您要在该地区创建数据集，您可能会考虑 cross-region dataset copies 加强您的灾难恢复策略。
- 我认为您可以将 table 数据导出到 GCS 以进行长期数据存储
因为还有一些storage classes。例如，
Archive Storage is the lowest-cost, highly durable storage service for data archiving, online backup, and disaster recovery.
