Обсуждение: [NOVICE] backup task target

Hi

How do I know if my full database is being backed up?

I have a script already in place that runs a nightly backup of a database called okay_db that runs this command:

/usr/lib/postgresql/8.4/bin/pg_dump -h 10.11.7.5 --username postgres okay_db --blobs --file ' + db + ' --format=custom --verbose --no-password'

It seems you're running PostgreSQL 8.4, that's way past EOL. If I were you, I'll consider upgrading.
If you just need to know if the backup process has terminated without errors, check pg_dump return value == 0. However, this does not assure you that your backup is "good".
There was a thread about a similar discussion some days ago,
http://www.postgresql-archive.org/How-Can-I-check-PostgreSQL-backup-is-successfully-or-not-td5946486.html

In general, AFAIK, the only way where you can be 100% sure that your backup is OK, so it can be used for recovery, is to pg_restore the file you just obtained into a test database whose schema is identical to the one you're backing up.

In PGAdmin III, okay_db2 appears to be under the main database called okay_db as well. How do I know which one is getting backed up? The whole database or just one into the server database?

So in pgAdminIII you can see all the 2 databases under Server/Databases, right?
As for the command you report in the OP, the one being dumped is okay_db. To dump the whole cluster (so all databases) you should use pg_dumpall, or issue a pg_dump for every database you need to backup.

HTH.
Cheers,
Moreno.

Sorry for the terminology not sure if I'm being clear as this is not my field of expertise
