Multiple pubs is not supported. The appropriate approach is to use some type of VM backup and restore solution. This could be some scripts that you run on VMware that back up the vmx/vmdk files and zip them up, or it could be a solution such as Veeam. That way if everything goes to crap you can do a full cluster restore to a known good state.

Hi Nizar,
          This is what I’m asking about, the client suggested this approach and I was asking about the pros and cons for such approach.

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.
