Zimbra Cold backup script by Brendan Horan

I don't need a hot backup solution for Zimbra I do try and sleep at night...

So I wrote the following script that will do the following :

stop zimba
tar the /opt zimbra
check the tar ball against /opt/zimbra * encrypt the tar ball
Email out the results.

Edit the following to suit your install :

BKDIR=/backup
ZMHOME=/opt/zimbra
TARTL=/
GPGUSR=zimbra
LLOC=/var/log
DESTINIATION@EMAIL

#!/bin/bash

BKDIR=/backup
ZMHOME=/opt/zimbra
TARTL=/
GPGUSR=zimbra
LLOC=/var/log/backups

DATE=`date +%Y-%m-%d`
ZMBVER=`su - zimbra -c '/opt/zimbra/bin/zmcontrol -v | awk '\''{print $2}'\'''`


function loghd() {
  echo "Starting Zimbra Full Backup" > $LLOC/ZM-FB-$DATE.log
  echo "Backup started on `date +%c`" >> $LLOC/ZM-FB-$DATE.log
  echo "--------------------------------------------" >> $LLOC/ZM-FB-$DATE.log
}

function zmstart() {
