The archive_timeout setting only indicates the time at which a new WAL archive is forced, no matther how much data has been written. If a WAL file fills up before the timeout is reached, it will fire the archive_command immediately and the timeout "timer" is reset. For example, we have a primary database instance where we see the archive_command fire every 1-2 minutes during peak, but our archive_timeout is set to 15 minutes. This ensures that the secondary database instance is getting updated even when there's not enough write traffic to fill up a WAL file. --Matthew Wood -- View this message in context: http://www.nabble.com/PITR-archive_timeout-Command-tp24788681p24923536.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
