Redis作为一个内存数据库，数据是以内存为载体存储的，那么一旦Redis服务器进程退出，服务器中的数据也会消失。为了解决这个问题，Redis提供了持久化机制，也就是把内存中的数据保存到磁盘当中，避免数据意外丢失。
Redis提供了两种持久化方案：RDB持久化和AOF持久化，一个是快照的方式，一个是

Redis的持久化功能在一定程度上保证了数据的安全性，即便是服务器宕机的情况下，也可以保证数据的丢失非常少。通常，为了避免服务的单点故障，会把数据复制到多个副本放在不同的服务器上，且这些拥有数据副本的服务器可以用于处理客户端的读请求，扩展整体的性能，一旦涉及到了分布式部署，就一定会考虑到数据一致性问
