+This is a simple cron job set up for backing up PostgreSQL databases to local disk.
+
+It consists of two files:
+
+1) pg_backup.sh - backup script doing the actual work
+
+- The backupdir must be created manually (mkdir pg_backups)
+- The backupdir owner must be changed to postgres (chown postgres pg_backups)
+- Script must be made executable (chmod 755 pg_backup.sh)
+- Script must be invoked by postgres user
+
+2) pg_backup.cron - crontab file invoking the script every day at 23:00
+
+- Crontab can be loaded with crontab command: crontab pg_backup.cron
+- Active cron jobs can viewed with: crontab -l
+- Cron jobs can be terminated with: crontab -r
