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);

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

postgres=# select pg_stop_backup('false');

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