In this episode, we chat with technical writer Bob Binstock about mirroring databases in InterSystems products — specifically in InterSystems IRIS. Bob is a technical writer at InterSystems with lots of knowledge about topics like these, and he walks us through the concept of mirroring for high availability. You'll hear about primaries and backups, journal files, failovers, and more.

Today I'm chatting with Bob Binstock about high availability and mirroring databases. Bob has a pretty wide purview of expertise, being a Technical Writer here at InterSystems. And one of the areas he's worked quite a bit on is mirroring. In our discussion, we'll talk about some of the reasons that applications today really require ultra-high availability, and then how mirroring and InterSystems IRIS and other products help to address that issue.
Derek Robinson 00:01:22 Welcome to the podcast Bob Binstock, one of the Technical Writers here at InterSystems. Bob, how's it going?
Bob Binstock Good. How are you?
Derek Robinson 00:01:30 Good, thanks. So today we're going to be talking about mirroring and high availability, which is an important topic for people that have applications running on InterSystems products, or really any products I think, in the world today, and with the way that software development goes and application development goes. So, before getting into the specifics of that technology and those features, let's talk about the concept of high availability in the first place. What is high availability, and why is it important for application development and for really any applications running today?
Bob Binstock 00:01:57 Well, what you just said is actually very accurate because more and more, everybody needs their applications to be online 24-7, 365. We used to talk about mission- critical applications that couldn't afford any downtime. But the fact is that organizations in healthcare, government, financial services, manufacturing, all sorts of areas, live on the network now. So essentially everything they do is mission critical. I mean, it may not seem so critical to me that I can buy something on Amazon right now, but it is to them. Their business is in trouble if they have interruptions. So high availability basically means zero downtime, or as little as you can manage. And that's what InterSystems IRIS mirroring is for.
Derek Robinson 00:02:49 Right, right. So, yeah, the Amazon one's a great example because it matters to their business,
