The following script is a modified version of one that can found on the Zimbra Forum here - http://www.zimbra.com/forums/administrators/15275-solved-yet-another-backup-script-community-version.html. It performs a full (offline) backup of your whole Zimbra installation. I've...

  • Changed some of the logging (added timestamps, reduced verbosity)
  • Added FTP option so that backup's can be FTP'ed off

See Zimbra Backup for a bit of guidance on how to run, and see Zimbra FOSS User Backup for how to perform an online, user only backup.

#
# What this script does:
# 1. Makes daily off-line backups, at a service downtime of ~ < 2 min.
# 2. Weekly backup cycle - 1 full backup & 6 diffs.
# 3. Predefined archive sizes, for writing backups to CD or DVD media...
# 4. Backup archive compression.
# 5. Backup archive encryption.
# 6. Backup archive integrity checks and md5 checksums creation.
# 7. Automated DR - Off-site copy of backup archives via ssh.
# 8. Install and setup function for needed software (Ubuntu Systems only)
# 9. Weekly eMail report & eMail on error - including CC address.
#
# This script makes use of following tools:
# apt-get, cron, dar, dpkg, mailx, md5sum, rsync, ssh, uuencode, wget, zimbra mta.
#
# We have opted to use a pre-sync directory to save on "down time", but this 
# causes one to have huge additional space usage.
# But hard drives are cheep today!
#
# What is still to come or needs work on:
# 1. Recovery option
# 2. Better documentation

##------- CONFIG -------#
# Edit this part of the script to fit your needs.

#--- Directories ---#
# Please add the trailing "/" to directories!
ZM_HOME=/opt/zimbra/			# where zimbra lives
SYNC_DIR=/tmp/fakebackup/		# intermediate dir for hot/cold syncs. must have at least as much free space as ZM_HOME consumes
ARCHIVEDIR=/Backup/zimbra_dars/		# where to store final backups
TO_MEDIA_DIR=/Backup/burn/

#--- PROGRAM OPTIONS ---# 
RSYNC_OPTS="-aHK --delete --exclude=*.pid" # leave these unless you are sure you need something else

#--- ARCHIVE NAMES ---#
BACKUPNAME="ZimbraBackup"		# what you want your backups called
FULL_PREFIX="FULL"			# prefix used for full backups
DIFF_PREFIX="DIFF"			# prefix used for differential backups
BACKUPDATE=`date +%Y%m%d`		# date format used in archive names
# BACKUPWEEK=`date +%W`  		# Week prefix used for backup weekly rotation and naming
# VJS - Commented out above, and added below to allow Weekly baseline to be any day of week.
#          Needs full set of tests to be run, including archiving old weeks data, etc.
BACKUPWEEKFILE="/opt/zimbra/backup.week"

esac
BACKUPWEEK=`cat $BACKUPWEEKFILE`        # Week prefix used for backup weekly rotation and naming

#--- ARCHIVE SIZE ---#
ARCHIVESIZE="4395M"			# storage media size, for full-backup archiving
# VJS - Uncomment next line for testing multi-DAR scenario on small mail store.
#ARCHIVESIZE="50M"			# storage media size, for full-backup archiving
COMPRESS="9"				# valid answers are 1 - 9 ( 9 = best )

#--- Encryption Options ---#
# !! !!! !!! CRYPT is a legacy option and should best not be used for future compatibility !!! !!! !!
CRYPT="no"				# valid answers are "yes" or "no" BEST IS LEFT AS IS
PASSDIR=/etc/`basename $0`/ 		# the directory the encryption hash is stored in. 
PASSFILE="noread"			# the file containing the password hash

#--- Log Settings ---#
EMAIL="admin@domain.com"		# the address to send logs to
# VJS - Added CC email to avoid errors sending report
EMAILCC="admin2@domain.com"		# another address to send to, blank for none
LOG="/var/log/zim_backup.log"		# log location
# VJS - Added chewitt suggestion for optional listing on report email
ATTACHLIST="no"				# attach backup file or not?
# VJS - Added FILTERLIST to remove all except changed or removed files from the listing
FILTERLIST="yes"  			# Answer "yes" or "no" - "no" lists everything. "yes" filters out unchanged files.

#--- SSH REMOTE DR COPY ---#
# This option will secure copy your archives to a remote server via 'scp'
DRCP="no"				# valid answers are "yes" or "no" 
SSHUSER="you"				# recommend creating a user on the remote machine just for transferring backups	
SSHKEY="rsa"				# recommended answers are "rsa" or "dsa" but "rsa1" is also valid.
REMOTEHOST="remote.server.fqdn"		# can use IP too
REMOTEDIR="/tmp/"			# where you want your backups saved.

#--- FTP REMOTE DR COPY ---#
# SSS - The options allows FTP'ing to a remote FTP server(!)
DRFTP="yes"				# Yes to enable, anything else not to
FTPSERVER="ftp.domain.local"
FTPUSER="backup-user"

# Built in hacks to fix common problems
#Hack to start Stats, even run zmlogprocess if needed
STATHACK="yes" 				# valid answers are "yes" or "no"
