If using pg_backup/pg_restore, then something like this is perfectly
adequate:
pg_backup ... $DB 2> backup_$(date +"%F_%T").log || mail -s "ERROR: backup
failed at $(date +\"%F %T\")" [email protected]
pg_restore --exit-on-error ... $DB 2> restore_$(date +"%F_%T").log || mail
-s "ERROR: restore failed at $(date +\"%F %T\")" [email protected]
Then you know to check the log file to see what happened.
My business users don't trust that, so I created a simple, fast, imperfect
script which I run at the same time as the backup:
BEGIN;
SELECT COUNT(*) FROM table_1;
SELECT COUNT(*) FROM table_2;
...
SELECT COUNT(*) FROM table_N;
COMMIT;
Run the same script on the restored database. The two log files have
always been identical.
