  2. Around 31:45 Chris Winter says Snapmirror Sync shouldn’t be applied to the same problems as async Snapmirror, that it’s a totally different use case. Can you clarify? Both do basically the same job (replicating data to another site), but one updates periodically and one updates on each I/O. So how do they apply to totally different use cases? I mean obviously you apply SMSync to applications that require zero RPO, but other than that how is it used differently?

    • My understanding is that SMSync gives you an exact replica up to the second, which is useful for applications that need to consume data as soon as it is written in different sites, whereas async is more of a DR replication use case. And with future releases, we’ll see additional functionality added.

      Does that answer your question?

      • Hm. I hadn’t thought about the use case of an “active consumer” at the destination. I’m not really sure that’s applicable, but maybe that’s the kind of “totally different use case” Chris had in mind?

        I thought SMSync was just intended for the standard DR replication use case, but used for RPO=0 cases, when lost data (for changes between async updates) was unacceptable.

        Thanks, Justin! Love your blog, BTW. Lots of fantastic info.
