【Azure Redis 缓存】Azure Cache for Redis 服务的导出RDB文件无法在自建的Redis服务中导入

问题描述

使用微软云的Redis服务，导出它的RDB文件后，想把数据恢复到本地自建的Redis服务中，发现出现如下错误:

问题解答

自建或从其他未经过特殊处理的Redis RDB文件，可以导入到Azure Redis服务中。但Azure Redis 导出的RDB文件会经过一些特殊处理，如适配Windows版Redis，导致它并不能直接导入本地的Redis中。所以遇见了以上错误。

如要进行转移数据，可以通过程序从Azure中读取所有的Redis Key 然后写入到本地自建的Redis服务中。
