如何共享PolarDB集群的备份集

当您需要将数据库备份提供给其他团队或合作伙伴进行数据分析、开发测试或数据迁移时，传统方式往往涉及复杂耗时的数据导出与传输。PolarDB的共享备份集功能简化了这一流程，它基于阿里云资源共享服务，允许您安全地将指定备份集授权给其他阿里云账号使用。接收方可利用该共享备份集快速恢复数据至其名下集群，极大提升了跨账号数据协作的效率与安全性。

PolarDB集群的数据备份是指在某个时间点上对集群的全量数据进行备份，生成一个备份集（快照）。该备份过程采用ROW（Redirect-on-Write）快照机制，直接存储在PolarDB集群的分布式存储系统上。在保存备份时，数据并未被真正复制。而当数据块发生修改时，系统会将历史版本的数据块保留给快照，同时生成一个新的数据块被原数据引用（Redirect）。本文将详细介绍创建备份、删除备份以及在数...
