Scenario :-

Setup a backup script to take daily, weekly and monthly backups to a remote windows server.  I wrote this bash script to meet the clients requirement and its worked  perfectly.  With some minor changes you can use the same script to setup daily ,weekly and monthly backup’s to the local linux server. I have setup separate scripts for daily, weekly and monthly backup’s. So that if somebody searching for the same scenario then they can understand the logic very easily.

Overview :-

1)  Created a folder ” backup ” in the remote windows server backup drive.

2) Created a user as follows

3)  Grant necessary  privileges  for this user to the backup directory as follows .

4 )   Mount the windows backup drive using /etc/fstab file follows ( with windows username and password )

//winserver/backup  /WIN_BACKUP  cifs  username=backup,password=pass 0 0

5)  Decided to run and setup  separate Daily , weekly and monthly backup scripts as follows

 

Crontab entries :-

#### Daily  backup at 03:01 am on  Monday to Satuarday
01 03  * * 1-6  /bin/bash /usr/local/scripts/daily_backup.sh > /dev/null 2>&1

##### Weekly  backukp – every  Sunday at 05:01 am
01 05  * * 0    /bin/bash /usr/local/scripts/weekly_backup.sh > /dev/null 2>&1

##### Monthly  backup – First day of every month at 06:01 am
01 06 1 * *  /bin/bash /usr/local/scripts/monthly_backup.sh > /dev/null 2>&1

 

Backup Script Files :-

 

1)   /usr/local/scripts/daily_backup.sh

#!/bin/bash
PATH=/usr/bin:/bin:/usr/sbin:/sbin
export PATH
## To find the day output will be like "Mon,Tue,Wed etc "
path=`date | awk '{print $1}'`
# Already created the folders Mon,Tue,Wed,..Sat inside /WIN_BACKUP/daily
# Backup scripts directory
rsync -avzub --copy-links /usr/local/scripts/   /WIN_BACKUP/daily/$path/scripts
# Backup website files 
rsync -avzub --copy-links  --exclude 'logs'  --exclude 'logs'  --exclude '*.tar'  --exclude '*.gz'  --exclude '*.zip' --exclude '*.sql'  /usr/local/www/   /WIN_BACKUP/daily/$path/UsrLocalWww

 

2)  /usr/local/scripts/weekly_backup.sh

#!/bin/bash PATH=/usr/bin:/bin:/usr/sbin:/sbin
export PATH
cd /WIN_BACKUP/website_weekly/
mkdir sun-`date +%Y%m%d`
cd sun-`date +%Y%m%d`
mkdir -p scripts
mkdir -p UsrLocalWww
# Backup scripts directory
rsync -avzub --copy-links /usr/local/scripts/    /WIN_BACKUP/website_weekly/sun-`date +%Y%m%d`/scripts
# Backup website files 
rsync -avzub --copy-links  --exclude 'logs'  --exclude 'logs'  --exclude '*.tar'  --exclude '*.gz'  --exclude '*.zip' --exclude '*.sql'  /usr/local/www/  /WIN_BACKUP/website_weekly/sun-`date +%Y%m%d`/UsrLocalWww

 

3) /usr/local/scripts/monthly_backup.sh

#!/bin/sh
PATH=/usr/bin:/bin:/usr/sbin:/sbin
export PATH
## To find the current month , out put will be " Jan, Feb, Mar etc " 
path=`date | awk '{print $2}'`
# Create the corresponding direcotries with current month
mkdir -p /WIN_BACKUP/website_monthly/$path/scripts
mkdir -p /WIN_BACKUP/website_monthly/$path/UsrLocalWww
# Backup scripts directory
rsync -Cavz /usr/local/scripts/   /WIN_BACKUP/website_monthly/$path/scripts
# Backup all websites
rsync -Cavz --exclude 'log'  --exclude 'logs'  --exclude '*.tar'  --exclude '*.gz'  --exclude '*.zip' --exclude '*.sql'  /usr/local/www/   /WIN_BACKUP/website_monthly/$path/UsrLocalWww

I took almost 1 day to complete this setup and now its running fine 🙂 . Hope that this documentation will  definitely help somebody, who is looking for the same setup.

For mysql daily,weekly and monthly backup setup check : MySql Backup Script

 

 

Scenario : –

1)      Take daily backup of linux server to local backup disk/secondary drive

2)      Copy the backup drive to the remote server.

( Using this method we can keep our data in 3 different places )

Setup Local Backup

1)      create a folder /backup

2)      rsync the necessary files to /backup

rsync -avzub /boot/   /backup/boot

rsync -avzub /usr/local/scripts/   /backup/User_local_scripts

rsync -avpuzb  –exclude ‘logs’ –copy-links –exclude ‘logs’  –exclude ‘*.tar’  –exclude ‘*.gz’ –exclude ‘*.zip’ –exclude ‘*.sql’ –exclude ‘log’  /usr/local/apache/htdocs    /backup/apache_htdocs

Copy the local backup to Remote server

Now all the necessary files are copied to /backup.  We need to copy this to a remote backup server for data redundancy .

I found Rdiff is a nice backup tool for copying folders overs a network.

Rdiff-backup:- is a very nice backup tool.We can copy one directory to another ,possibly over a network.The target directory ends up a copy of the source directory, but extra reverse diffs are stored in a special subdirectory of that target directory, so you can still recover files lost some time ago. The idea is to combine the best features of a mirror and an incremental backup. rdiff-backup also preserves subdirectories, hard links, dev files, permissions, uid/gid ownership, modification times, extended attributes, acls, and resource forks. Also, rdiff-backup can operate in a bandwidth efficient manner over a pipe, like rsync. Thus you can use rdiff-backup and ssh to securely back a hard drive up to a remote location, and only the differences will be transmitted. Finally, rdiff-backup is easy to use

1) Download rdiff  and install rdiff

yum install rdiff-backup ( easiest method )

Or you can download the tar and Install

Wget http://savannah.nongnu.org/download/rdiff-backup/rdiff-backup-1.2.8.tar.gz

2) tar –zxf rdiff-backup-1.2.8.tar.gz

3) cd rdiff-backup

4) ./configure

5) make

6) make install

7) Create a script to copy the directory to remote server.

vi  rdiff-backupTo-Remote.sh

#!/bin/bash

# hostname adminlogs.info

# this will copy the /backup folder to remoteserver /backup location

rdiff-backup /backup  remoteserverIP::/backup/adminlogs  > /dev/null 2>&1

8)  add this script to cron  ( execute the cron at 1:30 am  )

30  01 * * * bash  rdiff-backupTo-Remote.sh

NB :- You should allow password less login from the local server to remote server.

You can use the following  url to create the ssh password less login

http://adminlogs.info/2011/05/27/passwordless-login-ssh/

That’s it…You have successfully configured your backup script. You can relax , your data is safe and available in 3 disks 😉
