在以下链接中https://cloud.google.com/sql/faq它说:
MySQL Second Generation instances: The most recent 7 automated backups, and all on-demand backups, are retained. They are charged at the backup storage rate. Binary logs use storage space (not backup space), and are charged as storage.
是否可以保存更长时间的自动备份?(无需手动操作)
答案1
每文档,不。要么按需备份,然后按照所需保留时间删除,要么将数据导出到平面文件。
