rSync Script to backup ZeXtras backup to another server/location via SSH

[bugsysiegel]

Hi all,

I just had to register here, but I am not a new one to Zimbra and ZeXtras at all. I have started using Zimbra in 2005, when it was still in the infancy.

Anyway, I'm not here to tell my story, I'm here to give you one of my scripts - A VERY SIMPLE SCRIPT - which takes the ZeXtras backup your server is doing locally and transfers it over to another server via SSH/rSync ...

It's well commented, so I won't say more about it, however, I will answer all queries, so just keep asking. Here it is:

#!/bin/bash

# Zimbra Backup Script v0.0001
# Requires that you have ssh-keys: https://help.ubuntu.com/community/SSHHowto#Public%20key%20authentication
# This script is intended to run from the crontab as root
# Compiled from different resources by Oliver Bross - oliver@bross.eu

# the destination log file
BACKUPLOG="/var/log/rsync-backup.log"
# the destination directory for local backups
# example : DESTLOCAL=/opt/zimbra-backup/
DESTLOCAL=your-destination here
# the destination for remote backups
# example: DESTREMOTE="zimbrabackp.server.net:/Backup/zextras"
DESTREMOTE=and-the-destination-here

# Outputs the time the backup started, for log/tracking purposes
START=$(date +%s)
w
echo ZeXtras Remote rSync Backup > $BACKUPLOG
echo >> $BACKUPLOG
echo Time backup started : $(date +%a) $(date +%T). >> $BACKUPLOG

# Let's write few bits into the log file
echo >> $BACKUPLOG
echo Source : $DESTLOCAL >> $BACKUPLOG
echo Destination : $DESTREMOTE >> $BACKUPLOG
echo Backup Log : $BACKUPLOG >> $BACKUPLOG
echo >> $BACKUPLOG

# Am I root or not?
if [ x`whoami` != xroot ]; then
  echo Error: Must be run as root user
  exit 1
fi
 # exit 0

# backup the backup dir to remote
echo Syncing files started >> $BACKUPLOG
rsync -azrtqHK --delete $DESTLOCAL $DESTREMOTE >> $BACKUPLOG 2>&1
echo Syncing of files finished >> $BACKUPLOG
echo "(Any errors would be showsn abowe, if nothing shown, all went accoding to the plan!)" >> $BACKUPLOG
echo >> $BACKUPLOG

# Outputs the time the backup finished
FINISH=$(date +%s)
echo Time backup finished : $(date +%a) $(date +%T). >> $BACKUPLOG

# Lets see how log it all took
echo "Total Backup Time taken :  $(( ($FINISH-$START) / 60 )) minutes, $(( ($FINISH-$START) % 60 )) seconds" >> $BACKUPLOG
echo >> $BACKUPLOG

# Email some details over ... well, email the log file :-)
( echo "Subject: ZeXtras Remote rSync Backup results"; echo; cat $BACKUPLOG ) | /opt/zimbra/postfix/sbin/sendmail youremail@address.com

# end

ENJOY!

P.S.
just copy everything to whatever.sh file, change permissions to "X" and add schedule in the crontab file!

Hello bugsysiegel!

Welcome to the forums and thank you for your contribution, it's really appreciated!

Just couple more points:

1. do this first: https://www.digitalocean.com/communi...up-ssh-keys--2 ... what you don't want is for the server to wait for the password, the other server needs to accept incoming ssh connection without password ... that's just an example guide, there are plenty of others on the internet. If you struggle, just ask

2. don't forget to change the email address on the end of the script! You will receive an email with backup details and errors directly to your mailbox - fabulous!

Any questions, just ask.

awesome script

line 53 and 54 should be

# Email some details over ... well, email the log file :-)
( echo "Subject: ZeXtras Remote rSync Backup results"; echo; cat $BACKUPLOG ) | /usr/sbin/sendmail

vs

# Email some details over ... well, email the log file :-)
( echo "Subject: ZeXtras Remote rSync Backup results"; echo; cat $BACKUPLOG ) | /opt/zimbra/postfix/sbin/sendmail

for 8.7 zimbra correct path to sendmail other then that works great so far and appreciate the digital ocean link for ssh keys that was very useful

[root@zimbra ~]# ls -l /usr/sbin/sendmail
lrwxrwxrwx. 1 root root 21 Jul 29  2015 /usr/sbin/sendmail -> /etc/alternatives/mta
[root@zimbra ~]#

just in case anyone else has an error when trying to use with latest zimbra 8.7 save you some time
