I have zimbra server 7.1.1 configured on CentOS 6. And I am planning to build a Cold-standby server for any exigencies. Now my idea is to build another host on hypervisor and keep cold-standby.
Now I have following questions and would like to see the zimbra Guru's comments
1] Since this is open source, is it a good idea to keep server Cold-standby?
2] How can i replicate the data, I am thinking that configuring twice a day
3] Would rsync /opt/zimbra directories keep them in sync?
4] Is there any other method available for syncing between cold-standby and Production server?
Any other suggestion is welcome.
