I am using an evaluation version of Zimbra 4.5 Network Edition (zcs-NETWORK-4.5.4_GA_763.RHEL4_64). The OS is RHEL 4 64-bit edition.
As a part of evaluation, I tested the Disaster Recovery procedure as outlined in :
The 'DR' server was again a RHEL 4 64-bit box. At the end, I was able to restore the mails etc. for the users.
However, the command,
zmbackup -f -s mail.domain.com -a all
returns the following error:
Error occurred: authentication failed for zimbra
Interestingly, the backup allowed by the GUI mode is possible and completes successfully. But no CLI commands related to backup work- they all return the same error.
There are three issues which bother me and could narrow down the extent of the problem:
1) As per the Wiki, the backup files of the old server need to be copied on the new 'DR' server. Does this mean only /opt/zimbra/backup directory on the original server or some other files need to be backed up too?
2) The wiki mentions the following step:
Remove any old backup sessions because these sessions are no longer valid. Type rm -rf /opt/zimbra/redolog/* /opt/zimbra/backup/*
The presence of /opt/zimbra/redolog in above command is something which I can't understand. Does the folder have to be copied from old server? It's not at all mentioned in the Wiki.
3) The restoration of LDAP directory server is also not clear. It's mentioned that:
To restore the LDAP, type zmrestoreldap -lb <latest_label>.
If you are restoring large number of accounts, you may want to run this command with nohup so that the session does not terminate. Note: To find the LDAP session label to restore, type zmrestoreldap –lbs.
Now, here what does the 'latest label' mean. If the latest is an incremental backup, do we need to use that instead of an older full backup?
Thanks in advance for help!
