    Question Disaster recovery

    Hi.

    I've been trying to migrate my Zimbra 5.0.6 installation to another server.

    I've stopped all ingoing and out going connections with a firewall and started a full backup which completes successfully:

    Code:
    [zimbra@hermes ~]$ zmbackupquery
    Label:   full-20080604.125739.559
    Type:    full
    Status:  completed
    Started: Wed, 2008/06/04 14:57:39.559 CEST
    Ended:   Wed, 2008/06/04 15:13:16.681 CEST
    Redo log sequence range: 1 .. 1
    Number of accounts: 24

    But I cannot restore from the backup on my other server, because it tells me it lacks files containing ldap stuff:

    Code:
    [zimbra@janus ~]$ zmrestoreldap -lb full-20080604.114538.110
    Stopping ldap...slapd not running
    done.
    Can't read /opt/zimbra/backup/sessions/full-20080604.114538.110/ldap/ldap.bak: No such file or directory at /opt/zimbra/bin/zmrestoreldap line 169.
    I can find out why the full backup doesn't include the ldap.bak file?

    Thanks

    On the old Zimbra server:

    Code:
    [zimbra@hermes ~]$ zmcontrol -v
    
    
    Release 5.0.6_GA_2314.RHEL4_20080522092131 CentOS4 NETWORK edition
    New Zimbra server:

    Code:
    [zimbra@janus ~]$ zmcontrol -v
    
    
    Release 5.0.6_GA_2313.RHEL5_64_20080522105815 RHEL5_64

    That's not quite a disaster recovery, it's a move to a new server and architecture: Network Edition: Moving from 32-bit to 64-bit Server - Zimbra :: Wiki

    So the above is not supposed to work?

    On a 32-bit the ldap.bak file isn't needed?

    If you mean the method you've used, no it's not supposed to work. As I've already said, that's not a disaster recovery - a disaster recovery would be a restore to the same operating system and architecture. If you wish to move to the hardware you've described then use the instructions in the wiki article.

    Sorry for keeping asking questions I just don't understand the limitations.

    Why isn't the ldap.bak part of the full backup, wouldn't it be needed for a 32bit system restore as well?

    I just want to make sure that if the new 64bit server ever dies/crashes and all I have is a full backup I'm not in trouble because I didn't get a LDAP dump as well as a full backup.

    We recently did this, and you will need to export ldap from the 32-bit server to an ldif to be able to import it into the 64-bit ldap server.

    But the wiki article to which Phoenix is pointing you is the only way to do what you want to do.

    Hope that helps,
    Mark
