ICal Server in a Cluster

Question

Hi Community,
I would use iCal Server in 10.8. For my redundancy i would like to run it in a Cluster.
What's the best way to use the Calendar-Data  for both Sever?
I was found a Administration Guid for 10.6 but is no more actually for 10.8 Server.
I saw iCal use PostgreSQL for his Data?
May i should cone it?
Thanks for your help
Oliver

Hi,
This is not a supported configuration of Calendar Server as it exists in OS X Server. It's also a pretty advanced setup, with lots of moving parts and sharp edges.
That said, here's a document that outlines this configuration, for use with the open source distribution of Calendar Server  (which is the same as what ships with OS X Server):
http://trac.calendarserver.org/browser/CalendarServer/trunk/doc/Admin/MultiServe rDeployment.rst
If you want to experiment with this, I would recommend the following pre-requisites:
* practice backing up and restoring your configuration and data
* a test environment that you periodically refresh with your latest backup
* a rigorous approach, emphasizing things like checklists, step validation, and monitoring

In addition this is likely to get broken each time you update Apple's software - both OS X itself and especially Server.app
It is a shame Apple have gone backwards in terms of 'high-availability' features such as clustering and failover. This is an area that Apple could easily make themselves leaders in and differentiate themselves from numerous different (but admittedly workable) solutions used by other suppliers.
