[SOLVED] Yet Another Backup Script for Community Version

Postby blason » Wed Nov 28, 2012 1:27 am

OK - I am facing issue while stopping the services. I belive this was already covered up but my log shows

Setting date & version Marker into /opt/zimbra/DATE_VERSION.txt

Doing a hotsync of /opt/zimbra/ to /opt/Backup/tmp/fakebackup/

Disabling the Zimbra crontab...

Stopping the Zimbra server...

It seems the server was not able to stop the services properly. Does any one have fix for this? This happening almost every night.

[SOLVED] Yet Another Backup Script for Community Version

[quote user="heinzg"]Hi All
I have written the following script to suit my backup needs (it is actually quite a simple script...). I want to publish it here so you can have a good :D and maybe help improve on it and add functionality to it.
I admit some of the ideas come from existing scripts and ideas from forums.
I will maintain a current working version of the script here: Home*-*Open Source Office Lösungen
The Script Download now available again!
Script features:



  • Backups with or without strong encryption!

  • Optional Off-site copying of archives after creation

  • MD5 checksums for integrity checks of archives

  • Weekly backup rotation - 1 Full & 6 Diff's per rotation

  • Email report on Full backup

  • Email notifications on errors

  • Backup file lists (attached to weekly full backup report)

  • Installer & Setup option for quick deployment (install needed software and setup env e.g. ssh pki auth and cronjob helper)



Here is the code up to date code:



#!/bin/bash

## *** Info ***

# USAGE: -h or --help for help & usage.

# -f or --full for Full backup.

# -d or --diff for Diff backup.

# -V or --version for version info.

# --INSTALL for script install and setup.

#

# This is a backup script for the FOSS version of Zimbra mail server.

# The script is free and open source and for use by anyone who can find a use for it.

#

# What this script does:

# 1. Makes daily off-line backups, at a service downtime of ~
# 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 sofrware (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. Recover option

# 2. Better documentation

This is failing only for Diff Backup however works perfectly fine with Full backup. Any clue why?

Hi Team,
Just curious to know if the same script has ever been tried with ZCS v8.0? Was the backup and restore successful? Are we safe to use it in production environment?
