How to set up Backups

notifications

To get notified about the backups via email, a/the shell script may send emails via "mailx" - i.e Nail. => see http://klenwell.com/press/2009/03/ubuntu-email-with-nail/

Btw. postfix may work as well

=> ToDo: Install mail program

dump of the GeoNode DB - on CedeusDB

• create a shell script that contains the pgdump instructions - see /home/ssteinig/pgdbbackup.sh on CedeusDB
• test if script or script execution actually works. A simple script for testing may perhaps be this (/home/ssteinig/touchy.sh)

#!/bin/bash 
touch /home/ssteinig/ftw.text

• create a cron-tab entry for user ssteinig with "crontab -e"

  then add entry such as "00 01 * * * sh /home/ssteinig/pgdbbackup.sh" to run the script daily at 1:00 am

  => when using the user "postgres" to do the db dump

  • check if postgres user has a password assigned already (use ALTER... to do so: http://wiki.geosteiniger.cl/mediawiki-1.22.7/index.php/Setting_up_geonode#Some_PostgreSQL_commands )
  • create a .pgpass file to provide the password: http://wiki.postgresql.org/wiki/Pgpass

• check also if the cron is running: "sudo service cron status" otherwise start it...
• to see what the cron tab contains use "crontab -l"

=> ToDo: check how to open an ftp connection and place the file there... or retrieve it using "wget"?

Example geonodegisdb93backup.sh

#!/bin/bash
logfile="/home/ssteinig/geonode_db_backups/pgsql.log"
backup_dir="/home/ssteinig/geonode_db_backups"
touch $logfile

echo "Starting backup of databases " >> $logfile
dateinfo=`date '+%Y-%m-%d %H:%M:%S'`
timeslot=`date '+%Y%m%d-%H%M'`
/usr/bin/vacuumdb -z -h localhost -U postgres geonodegisdb93  >/dev/null 2>&1
/usr/bin/pg_dump -U postgres -i -F c -b geonodegisdb93 -h 127.0.0.1 -f $backup_dir/geonodegisdb93-backup-$timeslot.backup
echo "Backup and Vacuum complete on $dateinfo for database: geonodegisdb93 " >> $logfile
echo "Done backup of databases " >> $logfile
# sstein: email notification not used at the moment
# tail -16 /home/ssteinig/geonode_db_backups/pgsql.log | mailx blabla@blub.cl
