[cisco-voip] CUCM Cluster Redundancy

[Rob Dawson]

You would have to replicate it using something like Veeam or similar which isn’t supported. The subs will provide “mostly” normal operation until you can rebuild the pub node. I would invest more thought into a solid backup, recovery, and test plan.

Have a look at this - http://docwiki.cisco.com/wiki/Unified_Communications_VMWare_Requirements

Hi All,
          I have a UC cluster V10.5 on 2 UCS Blade servers having 1 Pub and 4 Subs, and I’d like to ask if there is any need or benefit from having a cold standby virtual machine for the Pub server (a replicated VM for the Pub which is turned off to backup Pub functionality in case of Pub failure), and also if the license will be valid on this cold standby VM for the Pub so that if the main Pub fails and we turned on the cold standby Pub VM everything will be fine and the operation continues normally.

Waiting your feedback.


Best Regards
