Hi Guillaume/team,
I set archive_mode = always in master and standby.
Archival to standby WAL directory completed when
·
standby server was restarted
·
pg_stop_backup was executed in master
But archival hangs when pg_stop_backup is executed in standby.
Could someone help to get this working?
postgres=# select pg_start_backup('test', true, false);
pg_start_backup

postgres=# select pg_stop_backup('f');

HINT: Check that your archive_command is executing properly. You can safely cancel this backup, but the database backup
will not be usable without all the WAL segments.

Hi team,
With non-exclusive backup method, trying backup from standby node.
But pg_stop_backup function returns “WAL archiving is not enabled…” and the logs are not archived to WAL directory configured.
Please check if I am missing anything in configuring this properly,
Server was restarted after setting the archiving params in postgresql.conf
Below is from version 14:
postgres=# select pg_start_backup('label', false, false);
pg_start_backup
-----------------
0/60000D8
(1 row)
postgres=# select pg_stop_backup('false');
NOTICE: WAL archiving is not enabled; you must ensure that all required WAL segments are
copied through other means to complete the backup

You're doing backups from the standby, and to allow archiving on the backups, archive_mode should be set to always.
