Script para backup do Zimbra FOSS

Segue abaixo um script que adaptei para realizar o backup do Zimbra FOSS utilizando rsync e enviando através de NFS para um servidor de backup, ao final é enviado um email informando os dados que foram recolhidos.
Para 70GB em uma rede 1Gb o backup está levando 1:16 sendo 26 minutos com os serviços desligados.
É só criar o script e adicionar ao Cron.


#!/bin/bash

 # Zimbra Backup Script
 # This script is intended to run from the crontab as root
 # Date outputs and su vs sudo corrections by other contributors, thanks, sorry I don't have names to attribute!
 # Free to use and free of any warranty!  Daniel W. Martin, 5 Dec 2008
 # Modified by Patrick Sarnighausen, 20 Dec 2010
 #              changed ftp to rsync through nfs


 # Outputs the time the backup started, for log/tracking purposes
 echo Horario de inicio do Backup = $(date +%T) > /mnt/nfsbackup/"Backup-`date +%F`.txt"

 before="$(date +%s)"

 # Live sync before stopping Zimbra to minimize sync time with the services down
 # Comment out the following line if you want to try single cold-sync only
 rsync -avogtHK --delete /opt/zimbra/ /mnt/nfsbackup/zimbrabkp/

 # which is the same as: /opt/zimbra /backup
 # Including --delete option gets rid of files in the dest folder that don't exist at the src
 # this prevents logfile/extraneous bloat from building up overtime.

 # Now we need to shut down Zimbra to rsync any files that were/are locked
 # whilst backing up when the server was up and running.
