Zimbra physical host crashed, left with NG Backup only

Post by BharathS »

Hello,

We have been running the following version for several years and today suddenly the server ran into a issue and we are being told it cannot be booted up normally and we have to salvage any data as backup from recovery mode and rebuild the server OS.

Version: zcs-NETWORK-8.8.8_GA_2009.UBUNTU14_64.20180322150747
OS: Ubuntu 14

currently we have NG Backup located at /opt/zimbra/ng_backup

I see the steps below, but does this restore require same version of zimbra and compatible ubuntu as the original or i can go with latest version of zimbra and OS and continue to restore from the NG backup done by older version of zimbra? the "/path/to/thhe/old/store" is /opt/zimbra/store?
The Recovery Process
Install Zimbra on a new server and configure the Server and Global settings.
Install Zimbra NG Modules on the new server.
Mount the Zimbra NG Modules Store folder of the old server on the new one. If this is not available, you use the last External Backup available or the latest remote backup.
Begin an External Restore on the new server using the following CLI command:
zxsuite backup doExternalRestore /path/to/the/old/store

The External Restore operation will immediatly create the domains, accounts and distribution lists, so as soon as the first part of the Restore is completed (check your Zimbra NG Modules Notifications) the system will be ready to be used by your users. Emails and other mailbox items will be restored afterwards.

NG backups are operating system and Zimbra version independent.

You can build a new Zimbra 9.0.0 server on Ubuntu 20 and run the external restore command against the file tree containing the backups from an 8.8.8 system that ran on RHEL6 for example.

Check out https://zimbra.github.io/zimbra-9/admin ... ith-backup for more details on the procedure.

Hope that helps,
Mark

Thank you, Appreciate your help, I could get the latest version of zimbra but up on activating the license it says its already activated, we don't have zimbra support either, is there any way to work with Zimbra to detach the old server from using the license so I can activate this new server using the same perpetual license?

Please assist. Thank you

I'm pretty sure if you have a perpetual license for 8.8.8 you need a current support contract for anything later.

By definition, a Perpetual license is keyed to the specific version of Zimbra you are running.

It’s the Support contract that gets you the right to upgrade to newer versions and open support cases.

You can reinstate Support, but you have to “buy back” support coverage from when it first expired, plus a 20% reinstatement fee. (This is no different than SonicWall and lots of other vendors).

Your VAR, indeed any Zimbra VAR in your territory, can help get you pricing.

Hope that helps,
Mark
