Analysis

Overview

The regular backup of the project creates two backup CDs that can restore fully the project in case of data loss.

Task requirements

• Test if the previous backup contains all needed information for restoring
  • Trac - wiki pages, settings, user accounts.
  • Svn - data, settings, user accounts.
  • Apache configurations
  • Postgres databases.
  • Testlink setup
• Modify the script if needed
• Execute the script
• Write the image on TWO dvds
• Make sure the copies are kept in different locations.

Task result

Backup media that is capable of restoring the whole project infrastructure.

Implementation idea

You can use SCS_BACKUP_R1 as similar consistency check is performed there.

How to demo

Explain what is done and where the media can be found.

Design

• Check if the previous back up contains all needed information for restore in the implementation phase.
• Because of its importance the postgres database must be set up to make periodical back ups
  • add following in the crontab

    c# m h  dom mon dow   command
    0 3 * * sun sh /home/scs/backup/backup.sh
    0 9 * * *   sh /home/scs/backup/psql_backup.sh
    

• Create following script psql_backup.sh that backs up postgres database:

  #!/bin/bash
  pg_dumpall -U scs -c -d > "/home/scs/backup/postgres/`date +%Y-%m-%d`.psql"
  gzip "/home/scs/backup/postgres/`date +%Y-%m-%d`.psql"
  

• Create script that backs up the build server in sophie:/home/build/backup/backup.sh (the function below creates recursive copy of the .hudson directory excluding the workspace directory):

  #!/bin/bash
  dirname="/home/build/backup/`date +%Y-%m-%d`"
  isofile="`date +%Y-%m-%d`.iso"
  mkdir $dirname
  mkdir $dirname/.hudson/
  
  copy() {
     for file in `ls "$1$2"`
     do
        if [ $file = 'Sophie' ]
        then 
           file="Sophie 2.0"
        fi
        if [ `echo "$1$2$file" | grep /sophie2/ | wc -l` -eq 0 ]
        then
           if [ -d "$1$2$file" ]
           then
              mkdir "$dirname$2$file"
              copy "$1" "$2$file/"
           else
              cp "$1$2$file" "$dirname$2$file"
           fi
        else 
        mkdir "$1$2$file" 
        fi
     done
  }
  
  
  copy /home/build   /.hudson/
  
  tar -cvvf $dirname.tar $dirname
  gzip $dirname.tar
  rm -Rf $dirname
  

• Execute the scripts to create two back up DVD's.
• They should be stored separately.
