Adáptalo a tus necesidades...este es el oficial q zimbra propone para
hacer el backup local..algo tan sencillo como detener el zimbra completo
y hacer un rsyn con determinados parámetros....esto lo añades como tarea
en el cron cada 15 dias a ejecutar a medianoche,para no afectar el
servicio en jornada crítica y listo...yo además hago un rsyn de los
directorios de los usuarios con los correos cada 3 dias...

# Zimbra Backup Script
# Requires ncftp to run
# 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!

services down
# Comment out the following line if you want to try single cold-sync only
rsync -avHK --delete /opt/zimbra/ /backup/zimbra
# 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.
