Thanks for the great and simple script. I made a few edits to allow for an archive directory and rsync to a remote server. I only made the edits to the diff_backup and msgdiff_backup functions. I also added a timestamp variable before the calls so the filename would remain consistent throughout the backup, archive and sync.

#!/bin/bash

# This script will do various backups of Zimbra depending on wich you choose,
# most of them are cold backups except the msg backup wich hot copies the 'store'
# folder for possible individual mail retrival. Be sure to change the variables below
# to point to where you got the zimbra folder and where you want it to be backed up to.
#
# This script must be run as root or a user with equal privileges or it will not work.
#
# Usage: ZimBackup.sh full	- For full backup (Cold)
#	 ZimBackup.sh diff	- For diffrential backup (Cold)
#	 ZimBackup.sh msgfull	- For complete message backup (Hot)
#	 ZimBackup.sh msgdiff	- For diffrential message backup (Hot)
#
# When you run this script via crontab be sure to add '> /dev/null 2>&1' at the end
# of the script like below or the tar command will fail for no apparent reason.
# 00 12 * * * ZimBackup.sh full > /dev/null 2>&1
