I have crossed the first step of setting up Zimbra on my mail server with a few Test Accounts. I must congratulate the Zimbra developers for putting together a fine suite. But, I find the Administrator's Guide available on the Zimbra homepage inadequate. What worries me next are these scenarios :

- How do I take backups of mails and other configuration settings ?
- How do I upgrade individual components of Zimbra ?
(The log file of clamav states that "Your ClamAV installation is OUTDATED!")
- If I have a disk crash and I had taken a copy of the folder /opt/zimbra how do I update the config files and other data files in a fresh installation ?

Any pointers are appreciated.
