Backup vCenter Server High Availability nodes

Using Veeam Backup to protect VCHA

The vCenterServer Appliance (VCSA) is becoming more and more important. Many vSphere-related services rely deeply on the availability of vCenter. So it was a logic move to make vCenter more available by having an active, a passive and a witness node of vCenter in your cluster. In case the active appliance breaks, the passive appliance will take over.

I’ve been experimenting with VCHA for a while. Although I’m not yet satisfied with the failover time (5-10 minutes), I think it is a move into the right direction. I wouldn’t call it “high” availability right now – maybe “elevated” availability. But nevertheless the failover time might be alright for many environments today and it is used for production. That raises an important question:

How to backup a vCenter High Availability node?

If you have a standalone VC you’ll just make a backup or replica and you’re finished. But VCHA consists of 3 components and before backing up you’ll need to find out which one is the active node, because VMware only supports VADP-based backups (VMware vStorage API for Data Protection) of the active node. There’s no point in backing up the passive node or the witness. Keep in mind that active and passive node may have switched roles since last backup!

vSphere Web Client vs. vSphere Client

Ein Argument, das viele Kunden vom Upgrade auf vSphere 6.5 abhält, ist der Verlust des vSphere-Clients (C# Client). Der auf Adobe Flash basierende Web-Client wurde nie richtig angenommen. Auch wenn einige Funktionen nur im Web-Client verfügbar sind, erledigen vSphere-Admins 95% ihrer Tätigkeiten im klassischen C#-Client. (Ich muss gestehen, ich gehöre auch dazu).

Dabei wird oft das beste Argument zum Upgrade übersehen: Der HTML5 vSphere-Client. Ursprünglich als Fling gestartet, ist er nun auch fest in vSphere 6.5 integriert. Er benötigt kein Flash mehr und überzeugt auch optisch durch die klaren Linien der Project-Clarity UI.

Runecast Analyzer – Getting started Guide part 2

Part 2 – How to update your Runecast Appliance

In the first section of this article-series I’ve shown how to deploy and setup Runecast Analyzer. Thank you all for the positive responses. In this section I’ll show how to update the appliance.

Once an update is available, Runecast Analyzer will show a notification in the upper right corner. An exclamation mark will appear beneath the link symbol.

This only works if you decide to grant Runecast Analyzer access to the internet. If you prefer to lockdown the appliance from external communication, it is possible to update with offline packages. I will first describe online updates (with internet connection enabled) and then offline updates. Continue reading “Runecast Analyzer – Getting started Guide part 2”
