Due to a hardware crash I have to reinstall Zimbra (8.03 Opensource) - I've a "plain" file based backup which was basically just a rsync of /opt/zimbra.
So I did not use any migration tool or hot backup script so far. I can not just copy it to the new server since a few files might be missing. The rsync failed from time to time due to hardware problem which also killed my "normal" backup.

I'd highly appreciate info on which files are mandatory to recover all domains, mailboxes, users and settings. So far I ensured that I've a copy of "store" what else is needed and what is the strategy to get the system up and running again in this specific case.

Thanks in advance!!
