Take backup of zimbra server

To take backup of Zimbra server use following steps:

1. Use "df -h" to check space occupied by all files stored in /opt. Verify that enough space is free on destination drive. Note that same set of files may occupy different space on a different file-system (ext3 to ext4)
2. Rsync /opt/zimbra to backup folder. This rsync should be done without stopping Zimbra. This is intended to reduce overall backup down-time

   rsync -vtrp --delete --sparse /opt/zimbra /backup/zimbra-yyyy-mm-dd

3. Stop running zimbra server by running 'zmcontrol stop' as user zimbra
4. Verify that all Zimbra processes have stopped using 'ps -U zimbra -u zimbra'
5. Again rsync /opt/zimbra to backup folder. This time backup would be consistent / stable.
6. Start zimbra again by using 'zmcontrol start' command as zimbra user

Restoring Zimbra from full file level backup

To restore Zimbra from full file level backup to the following:

mv /opt/zimbra /opt/old-zimbra
rsync <backup> /opt/zimbra   #mv or cp instead of rsync as appropriate
chown -R zimbra:zimbra /opt/zimbra
/opt/zimbra/libexec/zmfixperms

After this download the same version of Zimbra that was installed. It is important to remember the version number or not delete the installation directory. Again do './install.sh' of same version.

Do not use './install.sh -u' because all data would be lost.
