Hi again
9.2.4 on RHEL 6
I have a backup that runs by cronjob every day which is basically this:
00 19 * * * /backup_scripts/locsng_backup.sh > /cron/locsng_backup.out 2>&1
View /backup_scripts/locsng_backup.sh:
# carry out schema only backup of the db database
/pg_dumpall -l db -U postgres -s > /backups/pg_db_schema_backups/db_ci_schema_dump$date_of_backup.sql 2>&1
# carry out backup of db database
/pg_dump -Fc db -U postgres > /backups/pg_db_db_backups/db_ci_backup$date_of_backup
# carry out cluster wide metadata backup
/pg_dumpall -g > /backups/pg_cluster_dump/cluster_ci_medadata$date_of_backup.sql
Is there a best practise way of how to monitor this sort of backup?
- my initial ideas are:
1. Check by cron if /cron/locsng_backup.out > 24 hours old (of course this will not work if cron fails) and if so
notifythe DBA by email?
2. As part of the script check if cron/locsng_backup.out > 0 bytes in size (of course this will not work if cron fails)
andif so notify the DBA by email?
3. Does pg_dump, pg_dumpall return an error code if it is unsuccessful and can be trapped in same way and then used to
notifythe DBA by email?
Thanks in advance
