problem in making backup server

[arvinderpb]

Hello All,
I was making backup server for my production zimbra server with the help of

Scripts to sync to a remote Zimbra backup machine - Zimbra :: Wiki

I installed a new server for backup and given name backup.xxxxxx.com and my original server name is mail.xxxxxxx.com. newly server was working fine.
I go through all the steps given in above link and export my LDAP to a file e.g. on my production server.

openldap/sbin/slapcat -f /opt/zimbra/conf/slapd.conf -b "" -l /tmp/zimbra-ldap.ldif

After that I import the data in newly installed server with below commands.

rm -f openldap-data/*

openldap/sbin/slapadd -f /opt/zimbra/conf/slapd.conf -b "" -l /tmp/zimbra-ldap.ldif

Now when I start the zimbra server I got LDAP error e.g.

zimbra@backup:~/bin> zmcontrol start
Host backup.deepakfasteners.com
        Starting ldap...Done.
FAILED
Failed to start slapd.  Attempting debug start to determine error.
backend_startup_one: bi_db_open failed! (-1)

where is the problem??
