    This may be of help to you :-

    Hot backup question on open source?

    Do a search for disaster recovery as it has been covered quite a few times. Also it would be helpful if you were to update your profile with the output from
    Code:
    su - zimbra
    zmcontrol -v

    Yes you can but you would need to stop ZCS first so that the services are in a consistent state.

    Facts:
    -The DR Server will be all the time offline, and will iclude all mail boxes of users
    -The online and the DR have different operation OS RHEL5 64bit and Cento5
    64bit
    - The production allocated on separate LVM the DR on a filesystem under /
    - Both are used as internal server (Intranet) no-routable for outside
